T. history of our expedition is in several respects intimately connected with the name of my good friend, Prof. H. Moun. As stated in the Intro- duction to my popular account of the Expedition (“Farthest North”) it was after reading a newspaper article by Prof. Moun (in 1884) on the Jeanette relics that I got the first suggestion towards the planning of the expedition. Monn was one of the few who always believed in the practicability of this plan. He was one of the last friends to bid us farewell when we left Vardo in 1893, and by a strange coincidence he was also the first friend JoHANSEN and I met, when three years later we again went ashore, also at Vardo. This important volume is entirely Mouy’s work, and in now laying it before the scientific world I feel I could find no better opportunity of according him my special and cordial thanks for the valuable assistance he rendered the expedition in this and in other ways. At my request Professor H. Moun kindly took charge of the meteorological equipment of the expedition from the very beginning. In concert with me, he laid the plan of the meteorological work to be carried out during the voyage ; he ordered the instruments and tested them, and he gave Capt. Scort-Hansen the necessary instructions for making the observations, and pointed out how the whole meteorological work should be superintended. After the return of the expedition, he did me the great favour of under- taking to work up the voluminous and important meteorological material col- VI lected during the three years of the expedition. The results of his work, which has taken several years of his valuable time, are given in the present volume. I trust, however, that I do not go too far when I say that the contents of this volume will in several respects be an important step forward in our knowledge of the physical conditions of the atmosphere of our globe. The observations were taken in a hitherto entirely unknown region where the conditions are extreme, but they are at the same time exceptionally uniform, as we were moving the whole time slowly across an extensive and entirely ice-covered sea. I believe also that this volume will prove that the working up of our meteorological material could not easily have been placed in better hands. Captain Sieurp Scort-Hansen took charge of, and superintended, the meteorological work of the expedition during the whole voyage. I know that Prof. Monn, who has now followed this work from hour to hour and day to day, agrees with me that it has been carried out during the long and often hard time with an endurance and care which is more than admirable; in spite of the often very difficult and trying circumstances, there is hardly a gap in the series of observations. I have on two previous occasions in this report {Prefaces to Vols. I and II) gratefully acknowledged Scott-Hansen’s valuable services to the expedition; I could not send out this volume containing his many important observations without thanking him once more for his faithful work during the long polar day and the long, cold polar night. I also feel impelled to thank his two assistants, Captain Hsatmar JOHANSEN, and Mr. Bernuarp Norpaut, as well as the other members of the expedition, for their share in the meteorological work.

Scorr-Hansen for his valuable information con- cerning the observations themselves; to Miss Louise Moun, who made the main part of the computations; to Mr. A. Graarup, first meteorologist in the Norwegian Meteorological Institute, who made the harmonic-analysis calcula- tions; and to Miss J. Murr, who has revised my English manuscript. The proofs have been read by Miss Mohn, Mr. Graarud and Miss Muir. February, 1905. H. MOHN. ea Tey Se EP OE OM eee ered af Bir aie CONTENTS.

NOTE. “Blue sky” in the remarks below the Tables of Observations signifies “Water-sky” or reflection from open water. | Ne at atee Ree the meteorological observations given in the Tables above, Page 25 to 248, I have deduced the results set forth in the following chapters. These results comprise chiefly, the climatological elements and their diurnal and annual periods for that part of the circumpolar arctic ocean in which the Fram was drifting during the period October 1893 to August 1896. It is generally understood, that the determination of the mean values of the different climatological elements and their periods, requires a series of observations made during many years, and this is particularly true for the regions belonging to the cold zone. ‘The observations made during the voyage of the Fram only cover a space of time of not quite three years; but they are well made, with controlled instruments, many times each day, and what is of the utmost importance, in regions where the surface of the earth during the whole time was of a unique homogeneous nature, consisting of a level of frozen water with an uninterrupted free horizon. The distance from continents or islands was always considerable. The place of the Fram changed, it is true, not inconsiderably, particularly in longitude; so that the observations are far from being taken on the same spot, but the environs of the Fram were always so similar, that the factors having influence upon the climate may be regarded as a function mainly of the latitude and only slightly of the longitude, at least in respect of the diurnal variations of the climatological elements.

[NORW. POL. EXP. No. 17.] The accompanying diagram shows the position of the Fram in the differ- ent seasons according to the above given tables. The heavy black lines indicate the dark season or perpetual night, the parallel light lines the sunny season or perpetual day, and the small circles the equinoctial months March and September. The black circle shows the mean position for the dark season, the open circle the same for the sunny season, and the circle with a central point the same for the equinoctial months. The diagram shows at a glance the distance of the track of the Fram from Terra firma. WIND. DIRECTION. The number of the cases in which the wind had been observed blowing from one or other of the 32 points of the compass and of calms, was tabu- lated for each hour of observation and for each month separately. The num- bers belonging to the intermediate points N’E, NE’N, NE?*E etc. were distributed evenly, each with half their amount, among the adjacent 16 points N, NNE, NE ete.

This I have sought to obtain by collecting the numbers in the last table into the three following larger groups: 1, the dark season, comprising the months of October to February, during which the sun was altogether below the horizon, or — at the beginning and the end — only a short time above the horizon, but very low; 2, the sunny season, comprising the months of April to August, in which the sun was above the horizon during 24 hours; and 3, the equinoctial months March and September, in which there was regular day and night. The following 3 Tables give the numbers belonging to these 3 groups. WIND-FREQUENCY. DARK SEASON.

By means of Lambert’s formula I have computed from these numbers: 1, the N—, E—, S— and W— components of the winds’ direction for the different hours of observation, and their means for the day; 2, the deviations from the daily means, for each hour; 3, the difference N—S, and E—W; and from these, 4, the resultant direction (Dir.) and frequency (Res.) for each hour and for the daily means. The direction is given both in the usual quadrantal manner and also reckoned from North over East round the horizon. From the last numbers are deduced in the column , shift“ the shifting of the direction of the wind, a + meaning a shifting with the sun (veering), and a — against the sun (backing)}).

Sum of backing 389°, sum of veering 29°. The North component exceeds the South component continually from 7 a. m. to 8 p. m. The South component prevails continually over the North component from 8 p. m. to 7 a. m. The East component prevails over the West component continually from Midnight or 1 a. m. to Noon or 1 p. m., and the West component prevails conti- nually over the East component from 1 p. m. to 1 a. m. The periodical winds make the prevailing wind of the dark season more northerly during the hours about noon, more southerly during the midnight-hours, more easterly during the first part of the day, more westerly after noon until midnight. In the sunny season the wind veers generally with the sun. It backs only from 2 a. m. to 4 a. m., from 8 a. m. to 10 a. m. and from 6 p. m. to 8 p. m. Total veering 416°, total backing 56°. The South component prevails over the North component continually from 11 p.m. tot p.m. The North component predominates continually from 1 p. m. to 11 p. m. The West component prevails over the East component continually from 5 a.m. to 5 p. m. and the East component prevails (with one exception at 8 p. m.) from 5 p. m. to 5 a. m. The periodical winds make the prevailing wind of the season more southerly during the night and forenoon, more northerly during the afternoon, more westerly during the day, and more easterly during the afternoon and night. In the equinoctial months the wind shifts generally with the sun during the night and morning, and against the sun from 10 a. m. to 10 p.m. Total veering 410° and total backing 410°. The North component prevails over the South component continually from 3 a.m. to { p. m., and the South component over the North from 1 p. m. to 38 a. m., except at 10 p. m. . The periodical winds make the prevailing wind of the months more northerly in the morning and more southerly in the latter half of the day, more easterly before noon and in the afternoon, more westerly during the night and about noon. The diurnal period of the winds’ direction is a phenomenon which still awaits an explanation. The observations made at the Fram’s station give the winds as NO. 17.| WIND. 279 Mant.

The tables given and the results which I have set forth may, I hope, be of value in a thorough discussion of the subject. The different direction of the shifting of the wind in the dark and in the sunny season, seems to be of importance for the solution of the problem. WIND-DIRECTION. ANNUAL PERIOD.

The winds have mostly a tendency to change their direction against the sun, the farther West the place of observation lies. The fuller discussion of this subject must be deferred until we can take into consideration the prevailing movement of the air in each month, and the distribution of air- pressure. 286 H. MOHN.

We see in the Tables of observations that the direction of the wind is either the same or changes, from one hour of observation to the next. The change goes either with the Sun (veering) or against the Sun (backing). Counting, for each month, the number of cases in which the wind direction from one hour of obser- vation to the next is (1) constant, (2) veering, and (8) backing, and reducing the number of cases to 100, we obtain the following Table.

The constancy or steadiness of the wind direction reaches almost 50 per cent. The veering with the sun is nearly as frequent as the backing against the sun. The veering and the backing are fairly evenly distributed in all months over the whole wind-rose. I have not been able to find any preponderating tendency in the veering or backing to keep distinctly to certain rhumbs of the compass. On the other hand the winds with the greatest steadiness show a remark- able correspondence with the prevailing winds. Taking out (1) the most fre- quent direction of the wind from the Table, pages 280 and 281, (2) the dominant wind-direction of the windward side of the wind-rose Table, pages 284 and 285, (3) the resultant wind from the Table given at the end of this chapter, and (4) the wind of the greatest (and sometimes next greatest) constancy, we obtain the following Table. 988 H.

The computation was made for the 3 years of the drift of the Fram, taking the average for each month, e. g. October mean for 1893, —94 and —95. As September presented no clear days, July only 4, and June and August only one, I have taken for these months the days which give a mean amount of cloud of about 5. The following Table shows for each month the sum of the clear and of the overcast days, and the respective means of the diurnal velocity of the wind. 294 H. MOHN. METEOROLOGY. [NORW. POL. EXP.

The greater velocity of the wind accompanies stronger ascending currents of air, causing the formation of clouds. A clear sky with a lower velocity of the wind belongs to an anticyclonic, a clouded sky with a higher velocity of the wind to a cyclonic condition of the atmosphere. of differences (smoothed) from the diurnal mean, The following Tables show the diurnal period of the velocity in the form No. 17.] WIND. 295 October 1893, 94, 95.

NO. 17.] WIND. 299 The days with sky overcast show the ordinary period very well, particularly November and March with ranges above one metre per second. The periods for the seasons give a better oversight. Plate II. (1 em. = 1 m.p.s.). In winter there is almost no period; in spring the range with sky clear is only one half of the range with sky overcast; in summer the range with sky clear is twice as great as with sky overcast; in autumn, September excluded, the range is much greater with sky overcast than with sky clear. In the dark season there is no distinct period with sky clear. The relatively con- siderable amount of range with sky overcast — as great as the range with sky overcast in the sunny season — is due to the ranges of October and November. Of the equinoctial months, March has a much greater range with sky overcast than with sky clear. September is not suited fora comparison in this respect. The above tables indicate that the range of the diurnal period of the velocity of the wind is greater with a greater velocity, and vice versa. A further study of this relation seemed to me desirable, and the results of such study are set forth in the following tables. From the tables giving the velocity of the wind for each hour of observation, the days on which the mean daily velocity (v) was less than 45 metres per second, and the days when it was above 4°5 m. p. s., were taken out. For the months of the drift of the Fram, the mean velocity for each of these two groups and for each alternate hour, the corresponding diurnal mean, and the difference between this mean and the bi-hourly means (d), were taken.

Pl. Il (1 cm. = 1 m. p.s.). With the weaker winds, we have in the winter and in the dark season the minimum about noon, and the maximum at 2 a.m. This is the reverse of the general rule. The range is rather small. In the other seasons we have the minimum about 4 a. m., and the maximum about noon, with a relatively small range. With the stronger winds, the period has the ordinary run, with a minimum about 2a.m. and a maximum about noon. We have in winter and in the dark season a range nearly as great as in the other parts of the year, and in winter even greater than in summer. The spring and the equinoctial months show the greatest range. This seems to indicate that the diurnal period of the velocity of the wind is vastly more influenced by the average velocity of the wind during the day than by the change of the radiation in the course of the 24 hours. We have seen that a smaller amount of cloud and a lower average velocity of the wind during 24 hours generally give a smaller range of the diurnal period of the velocity of the wind, and that a larger amount of cloud and a higher velocity of the wind give a greater range of the diurnal period of the velocity of the wind. We have intimated (p. 294) that the first-named conditions point to an anticyclonic, the last-named to a cyclonic state of the atmosphere. In order to verify this relation, I have calculated the mean values of the pressure of the air corresponding to the velocities of the wind 304 H. MOHN. METEOROLOGY. [NORW. POL.

We know that anticyclonic winds are as a rule the weaker, and cyclonic winds the stronger. The remarkable magnitude of the range of the diurnal period of the velocity of the wind in the dark season, has induced me to calculate the relative frequency of the different wind-directions in this season, separately for weaker and for stronger winds.

November, strongest E, weakest W. As will be seen further on, the dyna- mic wind-roses for the dark season give as the strongest winds NNW and SSE, and as the weakest wind EK; for the sunny season, strongest wind KE, weakest SSW; and for the equinoctial months, strongest winds NE, weakest E. The frequency of the fresher winds has a diurnal period of a character similar to that of the velocity of the wind in general, as will be seen from the following Table.

The highest observed velocity of the wind being only 18 metres per second, we find no storm proper along the route of the Fram. The following Table shows in the first row the mean number of calms, reduced to bihourly observations, for each month (Table, p. 307). Dividing these numbers respectively by the total number of observations made in the month (12 >< number of days in the month), and multiplying by 1000, we get the numbers in the second row.

Calm days; 1 mm. = 1 day) It is above the mean from August to the end of the year, and below the mean from January to July. Calms are very rare as compared with cases with wind. The proportion is 18 to 982, or 1 to 55. DYNAMIC WIND-ROSES. Taking, for each month, the sum of the numbers expressing the velocity of the wind in metres per second, for each direction of the wind (32 points), and dividing the sum by the corresponding number of observations, we get a series of numbers representing the mean velocity of each of the winds blowing from the various points of the compass, commonly called the dyna- mic wind-rose, or the wind-rose for the velocity of the different winds. In order to reduce the wind-directions to 16 points, I have taken for the intermediate points half the sum of the velocities and half the number of observations, and added these halves to the sum and to the number for the adjacent 16 points; I have then added the 3 velocity-numbers and the 3 observation-numbers (weights), and divided the first sum by the last. 4 The following Table shows the numbers thus obtained. 1 The exact reduction is not one half, but 0.5 sec. 111/,°, or 05098. The resulting error in the computed mean velocity is very small, the addition of 0°98 per cent affecting the denominator as well as the numerator. [NORW. POL. EXP. METEOROLOGY.

THE DIURNAL’ PERIOD. For the determination of the diurnal period of the pressure of the air, I have taken the regular readings of the barometer made each second or fourth hour given in the “Observations”, and the registrations of the baro- graph. The latter were controlled by, and reduced to, the corrected observa- tions made with the mercury barometer. The hours of the barograph were controlled and verified by simultaneous comparisons between the position of the pen of the barograph and the stand of the chronometer Honwii 639 (Vol. II, No. 6, XIX), from which the exact local hour was computed from Prof. GrELMuypEN’s astronomical tables in Vol. II, No. 6, H, p. 86. These comparisons were noted at the beginning and the end of the barograph-sheets for each week, and also in the meteorological Journal for almost every day. By these means it has been possible to find the exact time corresponding to each registered value of the pressure of the air. For each observed and duly corrected height of the mercury barometer, the corresponding height registered by the barograph was read off the sheets. The difference is the correction to be applied to the registered values. For each hour the registered value was read off from the barograph-sheets, and corrected to the true pressure by means of the corrections thus found. As these generally varied somewhat, their magnitude for each hour was taken from a linear interpolation from one hour of observation to the next. This interval is generally 4 hours. No. 17.] ATMOSPHERIC PRESSURE. 317 The barograph stood in the cabin. It was kept going from the 6th July, 1893, to the 10th August, 1896. The registrations have been reduced from the 1st August, 1893, to the 31st July, 1896. The hourly values of the pressure of the air thus found are given in the following tables for each month from August, 1893, to July, 1896. The day is reckoned from midnight to midnight. The tables give the mean pressure of each day as the mean of the 24-hourly values in the hori- zontal rows, and the monthly means for each hour as the means of the numbers in the vertical columns. ‘The mean for the whole month stands as the mean of the numbers in the vertical column headed Mean, or of the numbers in the horizontal row of means. The hourly means have been corrected in the usual way! for the change due to the variation from the beginning to the end of the month, and reduced to noon in order to render them representative of the true diurnal period. The corrected values are given in the tables as Corr. in the last horizontal row but one. The last horizontal row, headed D. f. m. (Difference from mean) gives the Difference, 1. e. hourly corr. mean minus monthly mean, for each of the 24 hours.

The angular constant A, lies about 160° (max. hour 75 20™ p.m.) exceptin September. Its range a, varies between 0.041 mm. and 0.167 mm. and has maxima in February, July and September, and minima in April, September and December. The 12-hours Period. The angle A, oscillates around 297° (max. hour 5»5™), The general rule, maximum at 10" and minimum at 44, is here nearly reversed. The value of a, has a regular annual period, with maxima in February and September, and minima in December and July. The July minimum is the lowest. This corresponds with the general rule, viz. one minimum at the time of the Sun’s perigee and one lower minimum at the apogee. The value of a, for the year, 0.022 mm., is rather large for the high latitude of 82°. 7.

The change in the geographical position of the Fram has, of course, also some influence upon the change in the pressure of the air from one year to another in the same month. The smoothed curve gives a maximum of pressure, 761.47 mm., in April, and a second maximum, 760.5 mm., in December. The lowest minimum, 758.09 mm., we find in July,and a somewhat higher minimum, 758.65 mm., in February. The mean for the year is 759.55 mm.

It is only when we come to the weighted and smoothed numbers for the seasons that we observe something of a general rule. The winter, summer and autumn show minima at about ENE and at W, and maxima at N and S. This is also the rule for the Dark Season and for the Sunny Season. The spring months have minima at NNW (and at S), and maxima at E and WSW. The two equinoctial months differ from each other. March has minima at NNW and at SSE, maxima at ENE and at WSW, while September has its minimum at SW, and maximum at NNW. It is difficult to draw conclusions from the baric wind-roses as to the position and move- ment of the barometrical minima and maxima in the polar sea. The frequency of the minima of pressure with the winds from W and NE seems to indicate that the tracks of the barometric depressions lie both North and South of the position of the Fram. This question I shall discuss later on from other points of view. WIND-ROSES FOR THE CHANGE OF PRESSURE. From the Tables of observation, the number of those cases have been taken out in which the wind-direction has been accompanied by a rise or fall of the barometer. The change of pressure is reckoned from the fore- going to the following observation. The numbers for the intermediate points of the compass have been equally distributed over the neighbouring 16 points. The resulting figures were divided, for each wind-direction, by their sum, so that the figures given in the following Table represent the percentage of cases with rising (+) and decreasing (—) pressure, their sum being 100. The maxima are printed in larger type. H. MOHN. METEOROLOGY. [NORW. POL. EXP.

For the determination of the diurnal period of the temperature of the air, I have taken the regular readings of the thermometer made each second or fourth hour given in the “observations”, and the registrations of the thermograph. The latter were con- trolled by, and reduced to, the former. In some cases the registered temperatures could serve to correct apparently erroneous readings of the thermometer. The hours of the thermograph were controlled and verified by simultaneous compar- isons between the position of the pen of the thermograph and the reading of the chronometer Hohwii 639 (Vol. II, No. 6, XIX), from which the exact local hour was computed by Prof. Geelmuyden’s astronomical tables in Vol. II, No. 6, HL, p. 86. The said comparisons were noted at the beginning and the end of the thermograph-sheets for each week, and also in the meteorological journal almost every day. By these means it has been possible to find the exact time for each registered temperature. On a tracing-paper, laid over the thermograph-sheet, the corrected temperatures observed by the mercury or spirit thermometers in the screen were marked with fine dots in their true place with reference to time and value. The tracing-paper was then moved upon the thermograph-sheet so that the thermograph-curve could interpolate the temperatures corresponding to the intermediate hours between the fixed 2- or 4-hourly thermometric observations. The thermograph was kept working from the middle of October, 1893, to June 27%, 1896. From that day up to the end of July, 1896, the temperature at the odd hours was interpolated from the readings of the thermometers at the even hours. (For July, 1896, every 4* hour.) : In some cases, when the screwing of the ice made the registering unreliable, or the thermograph could not be kept going, the intermediate hourly temperatures have been interpolated graphically between the regularly observed temperatures. Such values have been printed in special type. The hourly temperatures thus found are given in the following tables for the time during which the Fram was drifting in the ice, from the middle of October, 1893, to the end of July, 1896. For each day are also given the lowest and the highest temperature. The day is reckoned from midnight to midnight. The minimum and maximum temperatures given in the tables are mostly those observed with a minimum or maximum thermometer. 51 402 H. MOHN. METEOROLOGY. [NORW. POL. EXP. The spirit minimum thermometer and the mercury maximum thermometer were set every day at 8 a.m. and at 8 p.m. Immediately before setting the minimum thermometer, the top of the spirit column and the outer end of the index were read. The first of these readings, compared with the simultaneous corrected reading of the dry thermometer, gave the correction of the minimum thermometer. This correction was applied, and the lowest temperature thus found between midnight and midnight was taken as the day’s minimum. When observations with the minimum thermometer were wanting, the minimum adopted has been taken from the corrected thermograph-curve. When the minimum tempera- ture, found from the corrected reading of the minimum thermometer, was higher than the lowest temperature from the corrected thermograph-curve, the latter has been adopted. In some cases the lowest temperature was found at midnight. This minimum tempe- rature has been taken for both the preceding and the following 24 hours. The maximum thermometers proved to be remarkably correct when compared with the dry thermometer at rising temperatures. When the temperature was below TEMPERATURE OF THE AIR. C°. 1893. OCTOBER.

The mean for the whole month stands as the mean of the numbers in the vertical column headed Mean, or of the numbers in the hori- zontal row of means. The hourly means have been corrected in the usual way? for the change due to the variation from the beginning to the end of the month, and reduced to Noon, in order to render them representative of the true diurnal period.

The codrdinates of the minima and maxima have been computed by a parabolic formula. The Table gives, for the months during which the Fram was drifting in the ice (reckoned from the 14* October, 1893), the mean Latitude and Long- itude, the periodical diurnal Minima and Maxima with the corresponding time, in hours and tenths, and the periodical diurnal Range as the difference between the Maximum and Minimum.

In the months of October, November, December, January and February, when the sun is scarcely above, or altogether below, the horizon during the 24 hours — our dark season —, we meet with different forms of the diurnal period. Only in 4 instances, viz. October 1894, November 1894, February 1894 and 1895, do we find the higher temperatures during the day and the lower temperatures during the night, but in 11 instan- ces we have the daytime colder than the night. In December there is a highest maximum about midnight, and a second maximum in the afternoon. A comparison between the amount of the diurnal range and the correspond- ing amount of clouds, seems to indicate that greater cloudiness is combined with a smaller temperature-range and vice versa. A closer approximation to the normal diurnal period is gained by taking the means for 3 (or 2) years of the values of D. f. m. for every month. These means are given in the Table below. This Table also gives the “mean ordinate”, the amount and hour of the minimum and maximum, the diurnal range, and the mean latitude and longitude for the month.

The range is small, but distinctly defined both in amount and direction. (Pl. HII. 1 em. = 1°). The solar diurnal period of the temperature of the air vanishes in the dark season. The period shown by the observations during this time must be ascribed to other causes than the radiation from the sun.

The difference is greatest (8°2) in February, and least in December (0°4). With the weaker winds (Pl. V. 1 cm. = 1° C.) the temperature in winter, autumn and the dark season, has its minimum in the day and its maximum in the night, or the ordinary period is reversed. As already pointed out (p. 472), this reversal seems due to the prevalence of colder northerly winds during the day hours and milder southerly winds during the night hours. In spring, summer, the sunny season and the equinoctial months, we have the ordinary diurnal period. The range is greatest in April (1°12) and least in July (0°°22). With the stronger winds we generally have the ordinary period. In winter and the dark season the maximum occurs late in the afternoon, and the range is only from 0°17 to 0°12. The greatest range (0°70) is found in April. 61 482 H. MOHN. METEOROLOGY. [NORW. POL. EXP.

The summer time has the smallest range, the most constant temperature. We find the greatest range in the winter half-year, particularly in February, and at the equinoxes. December has a secondary minimum. The smallest range occurs in July. The time about the equinoxes is the most unsteady as regards the diurnal temperature; the time about the solstices is steadier, that about the summer solstice being the steadiest.

The monthly numbers of cases or days with rising and with falling diurnal temperatures are in the 4*2 and 5‘ columns. 1 2 3 4 | 5 Temperature Mean Temperature rising falling || of 1 and 2 rising falling + = + Days Days January 1894—96.. 3°61 PA) | 3°97 16 15 February —»— 5: 06 4 49 4 74 123 15°7 March —>— 3° 85 4 10 3° 97 16 15 April —>— 2: 64 2 51 2: 56 15 15 May —— 2: 10 1597 2 03 19 12 June —>— 1° 06 0° 98 1° 02 153 14-7 July —»— 2. 0° 59 0° 52 0° 56 14. 17 August 1894—95.. 0° 78 1° 06 0° 91 165 145 September —»— ., 2 02 2 68 2 35 15 15 October 18983—95.. 3° 14 3° 97 3° 55 16°4 146 November —»— ., 3° 89 3° 95 3 91 15'7 14:3 December —»— .. 3° 62 3° 45 3° 53 153 1557 Mean and Sum .... | 2: 70 2 71 2: 70 186°5 178°5 No. 11.] TEMPERATURE OF THE AIR. 489 The columns 1, 2 and 3 show a very decided annual period (PI. III. 1 mm. = 1° C.). The interdiurnal variability is greatest in the winter time; the maximum lies in February, and is lowest in July. The numbers form ‘a very regular curve. The mean rising for the year is a little lower than the falling. The time during which the temperature is rising, is longer than its time of falling; it rises more slowly than it falls.

The frequency of this period is greater in the summer and autumn than in the spring and winter. The frequency of the other periods decreases with the length of the period, at first, up to the period of 4 days, very evenly, then more slowly to the longest period of 6 days, the frequency or probability of which scarcely reaches 0-1 per month. 492 H. MOHN. METEOROLOGY. [NORW. POL. EXP. The mean length of a period of ascending temperature is 2:00 days, and of a period of descending temperatures 1°93 days. The temperature rises at a slower rate than that at which it falls. We have seen that in the year it rises on 186°5 days and falls on 178°5 days. The lengths of the ascending and descending temperature-periods have an annual period. The periods are shorter than the annual mean both of rise and fall, from May or June to September, and longer in the other part of the year. The whole length of a period comprising the rise and the fall of the temperature, is on an average 3°93 days. It is shorter from June to Sep- tember, and longer from October to May, being longest in December, 4°7 days, and shortest in August, 3°1 days. THERMAL WIND-ROSES.

The difference between the warmest and the coldest wind is least in the summer months, being only 0°7 in July, and greatest in March and November (Pie \iieeeteroms.—" i.) The southerly winds being the warmest, and the northerly winds the coldest in the winter, goes far to show that the 82"4 parallel of latitude is hardly influenced by the Siberian “cold pole”. The slight variation in the temperature of the different winds in summer seems to indicate only a slight thermic gradient polewards during that season. A comparison of the mean temperature during calms with the mean lowest temperature, the mean temperature of the coldest wind, and the mean temperature of the month, gives the following results. 496 H.

The column Diff. 1—4 shows that the temperature with calms is sometimes lower and sometimes higher than the mean temperature (p. 483) of the respective months. The mean result obtained is that the calms are colder than the month in winter (—4°41) and autumn (-—0°4), and warmer in spring (+0°3) and summer (+0°°7), colder in the dark season (—3°1), warmer in the sunny season (+-0°4), and warmer in the equinoctial months (+1°5). We have seen (p. 481) that the temperature is lower with the weaker winds and higher with the stronger winds, except in July and August. We have seen, (p. 472) that the temperature of the air in the dark season is on an average a little lower during the day than during the night. We have seen (p. 278) that at the same time, the north component of the wind’s frequency is greater than the southern component during the day, and less during the night. The mean direction of the wind (p. 276) is S 51° E, with which there is a corresponding temperature of —29°2. When the wind backs towards the north, the temperature falls, when it veers towards the south, the temperature rises. With ESE it is —31°3, with SE —29-°5, with NO. 17.] TEMPERATURE OF THE AIR. 497 SSE —28°9. The diurnal variation of the temperature is in perfect accord- ance with the diurnal change of the direction of the wind in the dark season. In the crow’s mest of the Fram, 32 metres above sea-level, observations of the temperature of the air were taken simultaneously with the temperature in the thermometer-screen below. These are given in the following Table. The observations were made about noon. The Table shows the difference between the temperature at the height of the crow’s nest and that in the screen, the wind’s direction and velocity in metres per second, and the amount of cloud at the same time. The observations made in the crow’s nest are perhaps not so reliable as those made in the screen; and the result of thew comparison is scarcely capable of being utilised for a correct determination of the variation of the temperature with altitude. Meanwhile the great excess of negative differences tends to show that in the colder months an inversion of temperature is a phenomenon of very common occurrence. Temperature of the Air. Day. Cloud.

From October, 1893, to March, 1894, we have observations for every fourth hour. From April, 1894, to July, 1896, the observations of the hair hygrometer and the corresponding observations of the temperature of the air have made it possible to give determinations of the tension of vapour for the night and morning hours not contained in the Tables of observation, and thus to give complete results for every alternate hour of the day. mm gh | 4h | gn | gh | 10h |Noon|| 2h | 4h | 6h | Bh | Mnt, || Monthly | see aril is | | {S930 Ocieheceae 105 105 1-04 1-09 0-95 0-98 || 1:08 oe November 0°67 0°60 0°56 0:56 0°57 0:62 || 060 +) Deraaihes - 0°42 0-40 0-40 O44 ort 0-40 || O44 1894 January ..... 0-22 0-24 0-22 0-20 0-24 0-22 || 0-21 Se Rebrinryo os ost 0:33 0:33 0°31 0:28 030 || Ot ERE Marchesa toc: 0:23 0-22 0:23 0:23 0-22 0:23 || 0-98 MM Aprile eyo: 057 | 063 | 063 | 0-70 | 0:77| 080) 082 | 080 | 0:77] 0-70 | 067 | o60|| 071 Bet Maal tected) 157| £72! 157| 1:72 | 1:69] 184] +87] 200] 1:90 | 1:96} 1:78 | 186 || 1:79 # A sane eae 345 | 354| 348 | 362] 358] 372 |) 368| 378 | 366 | 367| 357| 360] 364 = July eee 4o7| 494| 430 | 442 | 441 | 444] 449 | 448 | 440] 436] 492 | 493 |] 4:36 Se Ancuste eee 382 | 387| 388| 403| 398| 399 || 399| 402] 392| 389] 3:87] 380|| 3:92 — September... .|| 203 | 219} 242 | 218 | 292] 936 || 937 | 933 | 231 | 298] 216] 248 || 998 Sy Orahen ee 060 | 060 | 057} 060| 065 | 067 || 0-66 | 064} 063 | O61 | 0:60 | O61 || 062 — November... .|| 024 | 033 | 025 | 031 | 0:30| 0-31 | 031 | 032 | 0:33 | 034] 0:32] 033 || 0:30 — December... .|| 017] 047] 017 | 0:20) 020| 0-21 | 021 | 020] 019 | 019] 020] 017]| O19 500 H.

The difference is greatest in the colder months, about 3:4 from January to April, and least in September, which month has the greatest amount of cloud. The weaker winter winds and the fresher summer winds give no appre- ciable diurnal period of the cloudiness. The general rule is that the amount of cloud is greater during the day than during the night, and that the diurnal range is greater with the stronger winds than with the weaker. Pl.

We find an exception in the cirro-stratus cloud, which has a chief maximum in January, and only a secondary maximum in July. Stratus has the largest range, and cumulo- stratus comes next. The total frequency in the whole year ranges thus — stratus, cirro-stratus, cirrus, strato-cumulus, cirro-cumulus and cumulus. True cumulus clouds are rather scarce even in the summer, and it is a question whether this form really occurs after all in its typical form. The expedition started in 1893, and the International Cloud-Atlas was published in 1896. CLOUD MOTION.

These sums, divided by the whole number of observations made at the respective hour in the month, give a fraction repre- senting the probability of precipitation for that hour. The following Table gives the diurnal period of this probability in thousandths, or per mille.

The westerly winds are much less frequently attended with precipitation, and calms very seldom. Taking the number of cases in which precipitation has been observed with a certain wind in a month, and dividing this number with the number of cases in which this wind has been observed in the same space of time, we get a number which gives an expression for the probability of precipi- tation with that wind.

As may have been seen from the remarks below the Tables of observation, the snow was very often observed drifting from the ground and the observations of the snow-gauge were consequently erroneous. It is therefore of no use to discuss them. The observations made with the rain-gauge can scarcely be called satisfactory, as snow-falls occur in every month, and oftener than rain.

[NORW. POL. EXP. THE TEMPERATURE OF THE POLAR ICE. Professor Nansen has sent me the following note about the observations of the temperature of the drifting polar ice made during the drift of the Fram. “I considered it very desirable that the seasonal changes in the thickness of the ice covering the Polar Sea, as well as the seasonal changes in the temperature at various depths in the ice, should be systematically investigated during the years the expedition lasted. Such systematic investigations had not, to my knowledge, previously been made, and they might evidently give very valuable results, if only satisfactory methods for the observations could be found. For measurements of the thickness of the ice, long, specially-constructed augers were used, with diameters of 2 inches (5'1 cm.) and 4 inches (10°1 cm.). The difficulty of these investigations proved to be that ice-pressure on several occasions disturbed the ice, so that the investigations could not be carried on at the same place during the whole expedition; and as the ice-floes were often of different ages, their thickness might vary a good deal, even though they were flat and not disturbed by ice-pressure. We did not therefore succeed in getting a continuous series of observations of the growth of the same ice-floe during the whole drift of the Fram; but our observations, when properly worked up, will nevertheless give valuable information as to the formation of the ice and its relation to the temperature of the air. Observations of the Temperature of the Ice at Various Depths. For these observations I had ordered 3 “earth-thermometers” from Necrertr & Zampra, as described in their large illustrated catalogue, § 57 (p. 42. See also figs. 48, 49). The thermometers (one maximum thermometer, and one slow-action thermometer) were lowered into bore-holes in the ice; No. 17.| THE TEMPERATURE OF THE POLAR ICE. 541 but as they would easily stick fast there when left for some time, they were often difficult to recover, and had sometimes to be dug out.! During an operation of this kind, one of the thermometers was broken.? I did not therefore, on the whole, consider the above method satisfactory. After several experiments, I adopted the following method. The bulbs of some ordinary thermometers (Séderbergs sling-thermometers) used for meteorological observations were enclosed in thick lumps of paraffine-wax. These thermometers were mounted in suitable holes at the ends of round wooden rods (in a manner similar to that of bath-thermometers in their wooden mounting). The rods were at least 20 cm. longer than the bore-holes in which they were placed, in order to give a handle by which they could easily be hauled up. The rods at several places were ‘ Hat 0 surrounded by muffs or cuffs of reindeer-skin with thick hair in order to prevent vertical circulation of air in the bore-holes. One such muff was placed close above the thermometer, another at the surface of the ice, and if WU eit tet) the bore-holes were deep, one or two in between. The arrangement was as shown in the figure. In cold weather, Mhy DoGro Ges the reindeer-hair of these muffs might freeze fast to the sides of the holes, but by a little force the rods could be torn loose. The observations met with most diffi- LLP PAE | fA TL Use UE ho Si erin a ve { | ; tt culties during the warm season, when the temperature __ SS SSSSSSSSSSSSSSS Hl ' ' ’ of the ice was relatively high.

For each observation the rods were hauled 1 As the bore-holes had to be fairly narrow, the thermometers would easily }freeze fast, or the plastic or viscous ice would often, after a few days, close round the thermometer, especially during the summer. 2 I believe this was in March, 1894, but unfortunately I have not been able to find a mention of the accident in my, journals. 542 H. MOHN. METEOROLOGY. [NORW. POL. EXP. up, the temperature-reading was taken at once, and the rods were again put down. The depth of the observations was measured from the surface of the ice to the bulb of each thermometer. There was as a rule only very little snow round the holes, and that was much trampled down. I received the impression that the observations on the whole gave fairly trustworthy results, but one source of error is the brine contained in the ice, which was apt to fill the bottom of the holes, especially the deeper ones, even during the coldest season; during the summer all holes were filled with briny or saline water, the salinity of which, however, decreased inversely as the temperature. As this brine would come from the pores of the ice and run down to the bottom of the holes, it is possible that during winter-time, when the temperature of the ice increased from the surface downwards, brine from the upper, coldest layers of the ice might sink down to the bottom of the hole, where the temperature was much higher, and as the freezing point of this very saline brine would be lower than the temperature of the bottom of the hole, it might influence the latter, and the temperature-reading might become too low.! In the warm season, when the temperature of the ice near the surface was higher than that lower down, the brine would naturally be less saline, and consequently lighter in the upper layers than in the deeper, as the salinity of the brine varied with the temperature of the ice: the freezing point of the brine would always be the same as that of the ice. In the lowest layers of the ice, below the depth of the minimum temperature, the temperature-reading might naturally become too low in the above manner, even in the summer. Although wood conducts heat relatively slowly, it is possible that the temperature-readings from the small depths near the sur- face of the ice, may have been slightly influenced in this manner, especially during the summer, when the upper ends of the rods projecting above the surface of the ice were much warmed by the radiation of heat from the sun. A still greater source of error might be due to the fact that in small depths ! This disturbing influence of the brine might have been avoided by a water-tight iron tube, completely filling the bore-hole, and sufficiently strong to withstand the pressure of the plastie or viscous ice, but unfortunately we had no material for making such tubes, and moreover iron tubes might also have a disturbing influence upon the temperature-readings by conducting the heat. If tubes of this kind were to be used, I believe it would be better to make them of a material that conducted heat slowly, e. g. glass, if it were not too easily broken. No. 17.] THE TEMPERATURE OF THE POLAR ICE. 543 the heat-rays from the sun or the sky penetrating the ice and the melting water (filling the holes), would be absorbed by the dark wood enclosing the thermometers, and that thus the temperature-readings became too high. This may explain the fact that temperatures above zero centigrade were observed in depths near the surface of the ice during summer. The observations of the ice-temperatures were made by myself until the middle of April, 1894. As I then thought I had formed a fairly satisfactory method of making them, I asked Capt. S. Scorr Hansen to undertake them as a part of the regular meteorological observations. During 1894, and I believe until the summer of 1895, these observations were made on a flat ice-floe on the port side of the Fram. This floe was formed on a wide, open water-lane about October 27th, 1898.” Fridtjof Nansen. The thermometers used for the observations of the temperature of the ice had been compared with the standard thermometer of the Meteorological Institute before the starting of the expedition. During the drift of the Fram, they were several times compared with standards and with each other, and after the return of the expedition, the thermometers then remaining were compared with the standards of the Meteorological Institute. The corrections were found to vary somewhat with the time, and may be uncertain up to some tenths of a degree C. The circumstances did not always allow of the same thermometers being used in the same depth. The holes into which the rods with the thermometers were put down required frequent cleaning, and they very often had fluid water (brine) in their lower part, this being sometimes pumped out. The place of the thermometers was changed several times, new holes being bored on the same ice-floe or the whole system removed to a new floe. The thickness of the floe in which the thermometers stood, was not constant. The numbers noted are the following: 1894. January 27. 1:37 metre 3 February 19. 1°87 , Snow 4 cm. es March 10. 201 , ee sar z April On aoe oe Baer to kes 5 5 10552:28", *- #.. 28, 544 H. MOHN. METEOROLOGY. [NORW. POL. EXP. 1895.

They may give the temperature of the snow, in which the thermo- meters were imbedded or a temperature influenced by radiation from or towards the sky (or sun). From the middle of April, 1894, to the end of June of the same year, the ice-temperatures were observed at 8 a. m. and at 8 p. m. The mean is taken in the tables.

The following Table gives the monthly means for the different years of the observed temperatures for the air, the surface of the ice, and the various depths. In order to obtain the mean temperatures for the depths of 0-4, 0°8, 1:2, 16 and 2:0 metres, I have calculated the missing values for each month and year by means of the formula log t, = log t, —f-h, where ¢, is the temperature at the depth h, ¢, at the surface, and f a coeffi- cient (the logarithmic decrement). The formula gives values, whose difference from the observed values ranges from 0°6 for the winter-months to 0°1 for the summer months. The computed values are enclosed in brackets. 560 H. MOHN.

As the figures for the surface are rather uncertain, I have not made use of them in the following discussion. As it will be seen, the annual series of the temperatures for the different depths is far from being homogeneous. We have some months for 3 years, some for 2 years, and some for only one year. An attempt to reduce them to the means of 3 years proved a failure. Generally the temperature of the ice rises and falls with the temperature of the air, but I tried in yain to find any rational coefficient of reduction, and in some months — for instance February (and November) — the temperature of the air and the temperature of the ice go in opposite directions. I have therefore taken the monthly means as they stand, and computed the annual periods of the temperature at the different depths directly for them. The want of homogeneity in the figures for the different months is thereby to a certain extent eliminated, because all the 12 numbers enter into the determination of the constants expressing the annual period. The weakest months are August and September, but happily the mean temperatures of the air for these months in 1894 and 1895 do not deviate from their general mean more than 0°7. The formula for the annual period which I have used, is tm = M-+-a.sin(A + m) t,, being the mean temperature for the month, M the mean annual tempera- ture, a the half amplitude or range, A the phase-angle, and m the angle Zh 562 H.

The difference is greatest in December. The sur- face of the ice, being covered, except during a short time in summer, with snow, is protected from cooling by radiation upwards, and receives heat from the underlying warmer layers. The upper free surface of the snow radiates heat freely towards the sky and space, and loses heat in a greater proportion than does its lower surface in contact with the ice, and the resulting thermal state of the upper surface is the main factor for the determination of the temperature of the air. This radiation goes on throughout the year. During autumn and winter, and particularly in the dark season, the cooling by radia- tion of heat from the surface of the earth is greater than the warming effect of the radiation from the sun, or is the sole agent. In spring and summer the radiation from the sun prevails over the radiation from the earth and the temperature of the upper surface of the snow, and the temperature of the air rises more quickly than that of the surface of the ice, which is prevented by the snow-covering from receiving the full effect of the radiation of the sun. The fact that the surface of the ice has a higher temperature than the air, is thus in full accordance with the natural conditions of the arctic ocean. The theory! of the propagation of heat in a soil of constant thermo- metrical heat-conductivity down to great depths requires that the different depths have the same annual temperature as the surface, and that the loga- rithmic decrements of the annual ranges of the temperature in the different depths are constant, and equal to the constant retardation of the phase with ‘ J.

The first condition is not fulfilled in the case of the polar ice, as we see from the Table, p. 562, the mean annual temperature, M, being higher than that of the surface, and increasing with depth. Nor does the second condition agree with our facts, as will be seen further on. The Table on p. 562 shows that the phase-angle decreases with depth. This signifies that the greater the depth, the later do the annual minima and maxima of the temperature occur. This lag or retardation of the heat-wave is proportional to the depth.

The computed annual and monthly temperatures of the ice at the depth of 3 metres are shown in the Table on p. 562.

In August, September and October, the ice is warmer than the water, from November to July, the water warmer than the ice. The total effect is that the colder ice in the course of every year causes the water to freeze, and thus adds to the thickness of the ice. On the other hand it may be remarked, that the temperature of the air on the route of the Fram is normally, as we have already seen (p. 483), above 0° for 18 days, from the 6% to the 24 July. In the sunny season the radia- tion from the sun cannot raise the temperature of the surface consisting of frozen water above zero; and its power is consumed in melting snow and ice. The air with a temperature higher than zero is derived from warmer regions by winds. The maximum temperature of the surface is 0°. The melting and evaporation of the ice at the surface at this time of the year are reducing the thickness of the ice. The period of melting is short, and it is during this period that the evaporation is effectual. As soon as the snow has begun to cover the ice, the evaporation from the surface of the snow begins, the surface of the ice being protected against evaporation by the covering of snow. The reduction of the thickness of the ice from its upper surface may be assumed to be comparatively slight. The isopleths on Pl. X show the following march of the temperature of the ice in the course of the year. During the autumn and the winter the surface is constantly radiating heat into the atmosphere and space, and its temperature decreases. As the lower layers of the ice have a higher temperature, increasing with the depth, there is a current of heat from below upwards towards the surface. From the beginning of November, the underlying water is warmer than the lower surface of the ice, and the upward current is thereby increased. This excess of the temperature of the water increases during the cooling of the ice from above, and the heat from the water militates against the cooling, and prevents the ice from reaching such low temperatures as it would do in consequence of the cooling from above through a sheet of ice with a thickness equal to 568 H. MOHN. METEOROLOGY. [NORW. POL. EXP. the depth to which the annual periodic variation of the temperature of the surface could extend its influence. The colder under surface of the ice causes the water in contact with it to freeze, and the water lower down to reach its annual minimum of temperature in winter or spring. From January to March, the surface minimum of temperature is travelling downwards through the ice. In spring the temperature of the surface increases, owing to the fact that the absorption of heat from the radiation of the sun is greater than the loss of heat by radiation and evaporation. A wave of heat is propagated downwards, and raises the temperature of the ice. At the same time the current from the water sends heat from below. The retardation of the wave from the surface causes the isopleths to take a more vertical direction, the vertical thermal gradient diminishes, and the effect of the current from below, unlike that of the autumn, is to cause a decrease. ‘The rise of the tempera- ture in spring almost corresponds with the fall in the autumn. At the end of spring or the beginning of summer, the temperature is nearly the same, about —3°5, at all depths of the ice. During summer the higher temperature of the air and the surface sends a heat-wave downwards, raising the temperature in the uppermost strata to zero, and continuing its course, with a certain amount of lag, to the deeper layers, where the temperature, between 0° and — 1°, becomes higher than that of the underlying water, and contributes to raise the temperature of the water to its summer or autumn maximum. In August the temperature seems to be highest at the depth of 1:2 metres, and to decrease from this depth upwards and downwards. In September the temperature steadily increases with the depth, but decreases on the whole in all depths. At the end of October the lower surface of the ice is cooled down to the temperature of the water. The reason why the temperature of the ice does not accord with the theory for the temperature of the soil is, as we have seen, to be found in the fact that the ice has not a sufficient thickness, and that there is an almost constant source of heat beneath it in the polar water on which it floats. The ice-covering protects the water from losing heat by radiation and evaporation. The conversion of water into ice on the under surface of the ice goes on at a slow rate, the latent heat given out in freezing being considerable, but every NO. 17.] THE TEMPERATURE OF THE POLAR ICE. 569 year it more than counterbalances the loss of ice on the upper surface, and every year adds to the thickness of the ice. Prof. Nansen has informed me that his observations show that the thickness of the drifting ice increased with the more westerly position of the Fram. When the ice formed in the Polar Basin reaches the North Atlantic Ocean and the Greenland Sea, and comes in con- tact with the Gulf Stream, it melts and loses in thickness. The observations of the ice-temperatures instituted by Prof. Nansen, and carried out, in spite of many difficulties, under the supervision of Capt. Scorr- Hansen, have thus, I believe, led to the discovery of important facts and an extended insight into the work of Nature in the high polar regions. 72 570 H. MOHN. METEOROLOGY. [NORW. POL, EXP. THE DISTRIBUTION OF ATMOSPHERIC PRESSURE AND TEMPERATURE OF THE AIR AROUND THE NORTH POLE. As the Fram reached higher northern latitudes than any well-equipped meteorological expedition or station, and brought back a series of exceedingly well made observations covering a period of three years, from a region hitherto unvisited by man, I have felt it worth while to construct new charts, showing by means of isobars and isotherms the distribution of the atmospheric pressure and the temperature of the air over the arctic regions, utilising for this purpose, and for the regions around the North Pole, the results found from the observa- tions made by the officers and crew of the Fram. In order to connect these results with those found for lower latitudes, I have extended the charts to the 60% degree of latitude, and for this purpose have made use of the following publications.

Besides these printed publications, I have been able to utilise the observa- tions made by Capt. Sverprur’s Fram-Expedition at Hayes Sound and Jones Sound, in the years 1898 to 1902. The charts, Plates XI—XIUII, give the pressure at sea-level and the stan- dard gravity. As we have no means for reducing the barometer-observations of the Fram to monthly normals, the position of the ship being too far from any regular meteorological station with a long series of observations, I have been obliged to use the Fram-observations with a certain freedom in drawing the isobars, taking sometimes a kind of mean for 2 or 3 years, and making allowance for the direction of the wind in accordance with the baric wind-law. Great assistance in drawing the isobars in the interior arctic regions is given by the observations from the continents and their shores, and from the islands repeatedly visited by scientific expeditions. In all months we find the North Atlantic minimum of pressure more or less developed. With the exception of June, in which month it lies over Southern Greenland, we find it in Davis Strait, southwest or west of Iceland, over the Norwegian Sea, and in the colder months farther eastwards in the north of Russia and Siberia. On the other side we find the Pacific minimum south of Bering Strait and in Alaska. The divide between these two regions of lower pressure extends from North America generally to Eastern Siberia. Its existence and position has already been pointed out by Prof. Supan, who has given it the name of “Die arktische Windscheide” (The arctic wind-divide).t ! Perermanns Mitteilungen 1891, p. 191. 572 H. MOHN. METEOROLOGY. [NORW. POL. EXP. From September to March we have maxima of pressure in North America and Siberia, in all months most strongly developed in Asia. The two maxima are connected by a ridge of somewhat lower pressure, forming the wind-divide. This ridge is located between Bering Strait, and the North Pole. It is probable that it migrates from month to month, but the abscence of observa- tions in this region does not, it seems to me, allow any reasonable conclusions to be drawn as to its movements. In April the high pressure in Siberia gives way, and the maximum pressure is located on the American side. This state continues during May, and at the same time the summer minimum in Siberia is steadily increasing in depth. In June we find the highest pressure over arctic North America and at Spitzbergen. In July and August the maximum lies between Greenland and somewhat east of Spitzbergen. The Atlantic minimum of pressure extends, from September to April, from Greenland far eastwards into the inner Arctic Ocean. From May to August it is much more feebly developed, and in June it is only found in the western part of South Greenland. The contrast between the distribution of pressure in the cold and the warm part of the year is also to be seen in the magnitudes of the pressure- gradients. These are stronger in the winter months, and much more feeble in the summer months. The pressure at the North Pole seems to have its maximum, — about 764 mm. — in April, and minimum — 759 mm. — from June to September. This gives an annual range of only 5 mm. Along the route of the Fram, from the New Siberian Islands to the north of Spitzbergen, the isobars indicate in the winter months south-easterly to easterly, relatively strong, winds on the north side of the Atlantic depres- sion, and in the summer months feeble winds from varying directions. This agrees with our Wind-Tables on pp. 284, 285 and 315. For the construction of the Jsotherms (Pl. XIV-—XVI, for the year PI. XX, Sea-Level) I have employed the following publications: 1.

The above remarks about the drawing of the isobars must also be ap- plied to the drawing of the isotherms. I have found the distribution of the temperature in the neighbourhood of the North Pole, given in the charts, by means of sections (latitude = abscissa, temperature = ordinates), along different meridians, the pole in the middle, and the known temperatures from the con- tinents or other stations on each side. Through the points plotted in this way, I have drawn the curve that seemed most probable. As regards the greater part of the regions north of the parallel of 60 degrees, the charts I have constructed do not show much difference from the recent charts of isotherms with which we are acquainted. Concerning the temperature at, and in the vicinity of, the Pole, the Fram-observations are likely to afford a nearer approximation to the truth, than the observations from lower latitudes. I have set forth the reason for the drawing of the isotherms for the interior of Greenland, in the memoir, no. 10 of the above named publications. I regard the strong radiation of heat in the thin air at the high level of this region as the main cause of the low temperature.

NO. 17.] TEMPERATURE OF THE AIR AROUND THE NORTH POLE. 575 The calculated mean temperature for July at the Pole being above the melting-point of ice is probably only to be regarded as a result of computation. The chart gives only — 1°. The annual Range of the temperature is shown on the chart, Pl. X. Maximum 66°, in Siberia; then comes North America with 45°, the North Pole with 42°, and Greenland with 40°. Minimum on the Atlantic and Pacific oceans. The North Pole has a continental climate. The annual migration of the isotherm for 0° C. is shown on the two charts, Pl. XX, one for the movement in the first part of the year towards the Pole, and one for the movement in the latter part of the year from the Pole. July is represented on both charts. The open Atlantic Ocean shows a very small movement of the isotherm for 0° in the winter months. In order to draw the isabnormal lines resulting from the temperature- charts, I first computed the normal or mean temperature for the latitudes 60°, 65°, 70°, 75°, 80° and 85° by taking out from the original charts, drawn on a larger scale, the temperature for each of these parallels and for each 10° of longitude, and taking the mean for each parallel of the respective 36 values. The result of this computation is shown in the following Table. NORMAL TEMPERATURE FOR LATITUDES January February March September October November December For each 5% degree of latitude and respective 10‘ degree of longitude, the difference between the temperature of each point and the normal temper- ature of the parallel was taken and put down on charts for each month and 576 H.

The line for 0° is drawn more heavily than the others. The lines for positive thermal anomaly are continuous, those for negative anomaly, dotted. It follows from the definition of the isabnormal lines, that the zero-line must go through the Pole. In the vicinity of the Pole, the thermal anomaly is small. The interior of Greenland has negative anomaly in all months. The Norwegian Sea has upwards of + 25° in January and February. The great continents have positive anomaly in summer (Siberia + 6°), and negative anomaly in winter (Siberia — 25° in January). The region between Bering Strait and the Pole has negative anomaly in all months, but generally less than 5 degrees. To conclude I must remark that the results set forth in this chapter, and drawn from the Fram-observations, may be modified in several ways by future observations in the arctic regions. No. 17.] BAROMETRICAL DEPRESSIONS AND THEIR MOTION. 577 BAROMETRICAL DEPRESSIONS AND THEIR MOTION. The observations of the pressure of air, contained in pp. 26 to 248 of the journal, and still more clearly the barograph papers, show by the fall and rise that cyclonic weather-systems, barometrical depressions, or “Lows”, were passing through the regions of the Arctic Ocean visited by the Fram. The great distance between the Fram and any permanent or temporary meteorological station, makes it quite impossible to construct synoptic weather- charts by means of which we could find the position of cyclonic and anti- cyclonic systems, and study their depths or heights, their gradients, and their motions. What the observations show, for this purpose, is only the variation of the barometer and the change of the direction of the wind. These observa- tions I have used in the following manner, in order to find out something more about the motions of barometric depressions, than the above-mentioned results from the general change of the direction of the wind (p. 287) and from the baric wind-roses (p. 399) and the wind-roses for the change of pressure (p. 400) have been able to do. For the latitude, g = 82°, and the friction coefficient, k = 0-00007, we have the normal angle of deflection! of the wind’s direction from the direc- tion of the gradient, @ equal to 64°. A line drawn to the left of the wind’s direction (the back to the wind) forming an angle of 64° with that direction will approximately show the direction of the gradient and the bearing of the centre of the depression. For each passing depression, such lines, drawn from the ship’s position, will spread out so as to cover a sector, and their mean Qosing 1 tan Nao 73 578 H. MOHN. METEOROLOGY. [NORW. POL. EXP. direction will more or less distinctly indicate the bearing of the centre when it was nearest to the ship; while a line perpendicular to this bearing will indicate the direction of the track of the centre. If the wind changes to the oppo- site direction, and the sector covers about 180 degrees, then the centre passes the ship, and the amount of pressure in the centre at the same time may be ascer- tained. A useful test is to make the diverging gradient lines, reckoned from the ship’s position, successively shorter with falling barometer and longer with rising barometer; but this cannot be done in all cases, as the lowest pressure appar- ently sometimes occurs before or after the nearest approximation of the centre. The change of the direction of the wind, or of the corresponding gradient lines, may also be irregular, sometimes going opposite to the usual direction of change. Irregularities such as these, where the motion changes its direction, even to the direct opposite, and also its rate, and the pressure changes at the very centre of a depression, are phenomena with which we are well acquainted from our own cyclonic systems. From the curves registered by the barograph, I took out the cases in which a depression amounting to upwards of 10 millimetres was observed. For each such case I drew, by means of the observed directions of the wind, the gradient lines and the resulting bearing of the centre of the depression when nearest to the ship, and the direction of the track of the depression.1 In some cases it was impossible to discover any regular motion of the depres- sion. These cases are omitted in the following Table. The Table gives, for each case, (14) The number; (2) the year, month and days; (3) the duration of the passage in days, approximately; (4) the direction of the motion of the depres- sion, the point of the compass (true direction) towards which it moves; (5) the bearing of the nearest approach of the centre to the ship; (6) the lowest pressure observed — at sea level; and (7) the highest wind-velocity observed during the passage. ‘ The same method has been used by professor Hitpesranpsson in his discussion of the observations from Pitlekai.

The frequency of depressions has a clearly- defined annual period. It has its maximum (4 per month) in January and February, and its minimum (0°7 per month) in June. The mean duration of the passage of a depression does not vary much in the several months or seasons; it is about 4 days. In the course of 3 years we find 73 depressions with a fall or rise of the pressure of upwards of 10 mm., or about 24 per annum. Their passage has lasted 290 days, which gives 97 cyclonic days of the above-mentioned force. The lowest atmospheric pressure at the Fram’s station during the passage of a depression varies from 771°7 mm. to 7241 mm., both in February. The distribution is as follows: 582 H. MOHN. METEOROLOGY. [NORW. POL. EXP. Pressure Number less than 725 — 775 to 765 mm. 765 - 75> — 755 - 745 — 745 - 735 — 735 - 725 — The mean is 7470 mm. The winter shows a little higher average than the other seasons. This is caused by the relatively large proportion of comparatively high minima of pressure observed in the depressions of the winter months. As the lowest observed pressures in most cases are higher than the pressure at the centre of a passing depression, the figures in the Table are in- capable of showing even an approximate value for the mean or absolute pressure of air in the centres of depression. We can only say that it must be below 747 mm. The next Table contains 10 cases in which the centre of a depression has passed the Fram. In these cases the lowest pressure has been 765°7 in December, 1893 7592 - April, 7589 - April, 7452 - February, 7445 - January, 7343 - March, 7342 - February, 7282 - February, 7273 - July, 7260 - March, 1896 1895 1896 1895 1894 1896 1894 1895 1894. The mean of these pressures is 742°3 mm., and we may take 740 mm. as an approximate value of the mean minimum pressure in a cyclonic centre. The lowest pressure observed on board the Fram is 7241 mm., on the 224 February, 1896. lower.

BAROMETRICAL DEPRESSIONS AND THEIR MOTION. 583 The velocity of the wind observed during the passage of depressions is not great. The highest is 18 m. p.s. and the mean of the highest observed is 97 m.p.s. The average velocity of the wind during the drift of the Fram is 45 m. p.s. (p. 309). The highest velocities observed in the various months are shown in the Table on p. 306. Their average is, for 1893, 15:2 m. p.s. - 1894,123 — - 1895,120 — - 1896,126 —- and for the whole period, 12°7 m. p.s. Judging from these velocities of the wind, the track of the Fram cannot be regarded as a stormy one, a fact which seems rather strange when we take into consideration the level nature of the surface of the earth. The coast and islands belonging to the Arctic Ocean show higher velocities of the wind. In published Reports I have found the following registered maximum velocities: Pitlekai (Vega, Nordenskidld) . . . . 1879 28:2 m.p.s.

There is a preponderance of depressions on the westerly side. In the first winter, the tracks of cyclonic systems lie chiefly north of the Fram; in the second win- ter, they are more evenly distributed on all sides, though those on the western predominate; and in the last winter, the tracks south of the Fram are by far the most frequent. The respective mean latitudes of the Fram are 79°, 82° and 85°. This seems to indicate that the general mean direction of track in 82° N. Lat. is nearly due East, the same result as found above. 74 586 H. MOHN. METEOROLOGY. [NORW. POL. EXP. The rate of the propagation of the barometrical minima cannot be properly found from observations from a single place. In order to arrive al an opinion as to this rate in the Arctic Ocean, I have made the following computations, requesting that they may be looked upon as mere experiment. The curve representing the values of the pressure in a regular barome- trical depression takes a sinusoid form in the vertical section through the axis. This may be represented by parts of similar parabolas, one with a vertical axis upwards through the centre, and two congruent pieces of parab- olas with vertical axis downwards, one at the front and one at the end of the depression. The parabolas meet on each side of the centre in symme- trical points situated at half the height of the total depression and at a distance from the centre of half the radius of the depression. In these points occurs the maximum dip of the curve or of the gradient, and also the maxi- mum of the velocity (v) of the wind. The abscissae (a), reckoned horizontally, are measured in degrees of meridian, and the ordinates (y) in millimetres. We have then in the parabola cies 2y d : = px?; + = = => Yy = pe’; a 2px = the gradient G, and x G" From the equations? 5 G sin a = 2wv sin pcos «= ke we get tan @ = ZEN ane 20 gv sin @ fu sin @ log u = 608768 9 = [8'67545] sett Taking the latitude g = 82° and the friction coefficient & = 0:00007 we get a = 64°. The mean pressure (b) being 750 mm., and the mean minimum pressure about 740 mm., I take for the maximum wind-velocity y = 10 mm. The mean temperature of the 73 depressions is —24°5. The velocity of the wind, the mean maximum, taken from the table on p. 306, equals 9°7 m. p.s. ' Zeitschrift der dsterreichischen Gesellschaft fiir Meteorologie. Bd. XII, 1877, p. 52. NO. 17.] BAROMETRICAL DEPRESSIONS AND THEIR MOTION. 587 From these data we get G = 1:82 mm. per meridian degree, and # = 11:00 meridian degrees or 1222 kilometres. The diameter of the depression is 4a or 4889 kilometres. Generally the centre passes on one side of the Fram, and the depression travels only along a chord of its circumference. Con- sidering this circumference to be circular, and the distance of the chord equal to a, the length of the chord is 4x X sin 60° or 0866 4a or 3°464a, or “4933 kilometres. This chord is traversed in 4 days, or 96 hours. The rate of propagation is 4233: 96 or 44 kilometres an hour, or 12:2 metres per second. Taking separately the 10 cases in which the centre has passed the Fram, we get a rate of 54 kilometres an hour, or 15 metres per second (b = 751°6 mm.; y = 7516—7423 = 93 mm.; t= — 25°3; v=89m.p.s.; G = 1675; w =11°10. Duration = 38 days). In our European depressions, we frequently have a rate of 40 km. per hour (11 m. p.s.), and 90 km. an hour (25 m. p. s.) has been found several times. In North America we have on an average 12°8 m. p. s., on the North Atlantic Ocean 81 m. p.s., and in Europe 75 m. p.s. In Europe, the mean rate is greatest — 9 to 10 m. p. s. — between Iceland and Norway, and least — 6 m. p. s. — in Finland. The above-calculated rates for the Arctic Ocean — 12 to 15 m. p. s. — are of the same order as those found by means of synoptic charts in other parts of the globe. 588 H. MOHN. METEOROLOGY. [NORW. POL. EXP. THE DIURNAL AND ANNUAL PERIODS OF THE METEOROLOGICAL ELEMENTS IN THE ARCTIC CIRCUMPOLAR SEA. We have seen that the diurnal and annual periods of the meteorological elements described above exhibit some features known from other parts of the world, but also some features which seem peculiar to high latitudes and to the low, flat ice-desert in which the Fram was drifting. In order to obtain a better insight into the processes going on in the lower atmosphere in these regions, pre- viously unexplored, processes resulting in the periods, I have found it appro- priate to put together the following considerations. The main factor in these processes is the radiation from the sun. In order to find an expression for the force and effect of this radiation, I have made the following computations for each mean month of the drift of the Fram (mean of 3 or 2 years). The mean latitude, g, for each month has been taken from the Table on p. 471; it is the mean latitude at noon. The declination, 6, of the sun’s centre, is the mean of the declinations at mean local noon, computed from the Tables of the Nautical Almanac. The altitude, a, of the sun’s centre is at noon a=d6- (90°—q) at midnight « = d—(90°—¢) The hour-angle, ¢, of the sun’s centre, when the upper limb of the sun is on the horizon, is found by the equation cos €—sin p.sin 0 cos (= cos m.cos 6 No. 17.

The depression of the sun’s centre is r++, 7 being the sun’s semi-diameter, and @ the horizontal refraction. I have assumed that 7 equals 16’ and @ equals 40’, according to the low temperature (in the dark season — 30°C) prevailing during the drift of the Fram. Hence 7 + 9 = 56’ and, for logarithmical calculation, 2 s U a i ee (pe sin =sec m sec d sin (Ae pie) sin SS For the corresponding azimuth of the sun’s centre a, we have sin @ = sinft.cos d.cosec € =sin¢. cos 0. cosec 90° 56’. When the sun is below the horizon, and the depression of its centre is less than about 16°, we have more or less of the sky illuminated by the sun. This is the Zwilight. The highest point of the line of demarcation between the twilight and the shadow of the earth lies in the vertical of the sun. Let Ca = Cb=Cc be the radius of the earth (R) and © CS a ray from the sun’s centre through the centre of the earth, © a another ray which would be tangent to the earth in @ if there were no refraction in the atmosphere. The ray from the sun’s upper limb would be tangent in the point b, the angle aCb being equal to the semi-diameter (r) of the sun. The ray from the upper limb of the sun will be deflected by the horizontal astronomical refraction (g) so as to touch the earth in a point c, the angle b Ce being equal to g. From the point c the ray pursues its way through the atmosphere and becomes deflected by the terrestrial refraction from the direction of the tangent cd, so as to meet that highest layer of the atmos- 590 H.

MOHN. METEOROLOGY. [NORW. POL. EXP. We see from this Table that the visible radiation from the sun reaching the surface of the earth in the dark season, is only indirect, or brought about by means of the sky or the twilight, and that it is inconsiderable, particu- larly in December, even at noon; while there is no radiation from this source reaching the surface of the earth at midnight. In the equinoctial months, at noon, we have both the direct radiation of the sun, and that of the sky or twiligth, but at midnight only the radiation from the latter. In the sunny season we have to do with both kinds of radiation, at mid- night as well as at noon. The difference between the amount of the total radiation at noon and at midnight, or the diurnal range of the radiation, on a unit of horizontal sur- face, has an annual period with a minimum in December and a maximum in the summer months. The fact that the maximum in our Table is to be found in August and not earlier, is due to the relatively lower mean latitude of the Fram in August. The diurnal variation of the radiation is the chief factor that determines the diurnal periods of the various meteorological elements. The principal meteorological effect of the radiation from above, is the heating of the atmosphere and the surface of the earth. This surface consists, in the present case, during the whole year, chiefly of frozen water, snow and ice, and only in the summer months partly of melted water. The energy of the radiation is mainly exerted in warming and evaporating ice, and in sum- mer in melting and evaporating ice, and partly warming and evaporating the melted ice. On the other hand, radiation of heat from the surface of the earth into space, the sky and the clouds, is always going on. The radiation from the sun and sky, and the radiation from the earth, have the greatest effect when the sky is clear. The effect of both radiations upon the surface of the earth is checked by clouds. With an overcast sky the radiation from above is screened off, more or less, from the earth, and the radiation from below is radiated back to the surface of the earth. The radiation from the sun tends to warm the surface of the earth, and the radiation from the surface to lower its temperature. Which of these No. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 597 radiations prevails over the other, and whether the resulting effect is to warm or to cool the surface of the earth, and to cause the temperature of the air to rise or to fall, are questions dependent chiefly upon the altitude of the sun. That the radiation from the twilight has an appreciable heating power seems to be distinctly proved by the observations from the Fram. We have found the annual minimum temperature of the air to occur as early as the end of January or the beginning of February (p. 483, and note, p. 484), though the sun appears above the horizon as late as about the beginning of March. In the mean time, the twilight is rapidly increasing in duration and extent (Table, pp. 594, 595), and seems to act as a heat-twilight (Warme-Dimme- rung), as Dove has called it. The diurnal period of the velocity of the wind (pp. 292 and 293, PI. I) comes out very distinctly in the different seasons, with a minimum in the night and a maximum a little past noon, in accordance with the general rule found elsewhere in the lower strata of the air. The range is small, only a fraction of one metre per second. This phenomenon is generally explained by the Espy-Képpen theory. This theory requires 1st that the velocity of the wind increases from the surface of the earth upwards, Q"ly the presence of ascensional and descensional currents in the atmosphere, and 3Uy that these currents be more strongly developed in the day-time than in the night. We know that the diurnal period of the wind’s velocity is generally well developed on land stations in latitudes where the sun shines during the day, and feebly, or not at all, on the sea. In the former case we have the more or less rugged surface of the earth acting as a resistance to the wind, and causing the lower air to move more slowly than the higher layers, and present- ing different conditions in adjacent patches of the surface for absorption of 598 H. MOHN. METEOROLOGY. [NORW. POL. EXP. the rays of the sun and atmosphere, and for radiation unto the sky, thus for the heating or cooling causing convectional currents. In the latter case we have a more or less smooth surface of the same quality throughout, reflecting the heat-rays and consuming their power by evaporation, without being able to produce differences of heating sufficiently strong to cause convectional currents comparable in strength with those on land. The conditions under which the Fram was drifting across the arctic polar sea are in many respects different from those of ordinary meteorological stations. On a large scale, the surface of the earth is a level surface like the sea, the horizon is free, and no mountains or hills disturb the uniformity of the level. But on a small scale this surface is not at all level; it is rugged in the extreme, and presents hillocks and furrows, elevations and depressions, while the pressure-ridges form a network extending in every direction. And the physical nature of the surface, like that of the sea, is of a particular homogeneity, consisting as it does of frozen water in the form of snow or ice, and only in the middle of summer partly covered with liquid water. The rugged surface of the ice acts as a resistance, causing the lowest layers of the air to move more slowly than the higher layers. The condi- tions for an increasing velocity of the wind with elevation were amply full- filled in the case of the Fram. No direct measurements of the velocity of the wind were made with the anemometer at different heights, but Professor NanseEn’s experience, as he has told me, was that the wind at the crow’s nest, some 32 metres above the water-line (Vol. I. Pl. II) was always much stronger than at the height of a couple of metres above the surface of the ice. The conditions for creating ascensional and descensional motions in the air above the polar ice are the same as on land. (1) The radiation from the sun or the sky heats the surface, but the amount of this heating depends on the absorbing power of the surface. This power varies in snow, ice and water. The absorbing power of the snow may vary with its degree of freshness, compactness, or purity; that of the ice with its degree of roughness, transparency, or purity; and that of the water with its degree of agitation or saltness. The effect of the radiation also depends upon the inclination to the horizon of the respective surface-element. The sunny side receives more heat from the sun or the atmosphere than the opposite or shady side. Under these circumstances, different parts or adjacent NO. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 599 patches of the surface become differently heated, and we have as a result convectional ascending and descending currents. A higher temperature is followed by a greater evaporation, and the greater lightness of the air produced by the aqueous vapours adds to the ascending power of the warmer parts of the air. The radiation upwards from the surface may also be locally different and create differences of cooling. But the general cooling of the surface by radiation tends to make the air above it heavier, sinking and stagnant. The calms are more frequent in all seasons in the night than in the day (pp. 307, 308; Pl. I). (2) When there is a wind, the obstructions presented by the rugged surface of the ice will force the air-current to rise on the windward side, and to descend more or less directly on the leeward side. The stronger the wind, the greater will be the effect of the ruggedness in creating ascensional and descensional motions of the lower air. All kinds of radiation are generally checked by clouds covering the sky, and this check increases with the amount of cloud. When the sun is above the horizon, detached clouds may sometimes increase the radiation of heat from the sky. The radiation from the sun and the atmosphere has a diurnal period with a maximum at noon and a minimum at midnight or during the night. The convectional currents in the lower air caused by this radiation must have the same diurnal period, and the result is the diurnal period of the velocity of the wind. The descensional currents bring the upper air with its greater velocity down, and the ascensional currents carry the more slowly moving lower air up from the surface of the earth. The higher the sun, the more rapid is the convection; and the fresher the wind, the more does the effect of the obstructions increase the force of the ascensional and descensional currents. The lower the sun, the more does the radiation from the surface of the earth tend to make the lower layers of the air quiet. The Tables on pp. 292 and 293, and PI. I, show that the diurnal period of the velocity of the wind comes out as on land-stations with a maximum near or a little after noon, and a minimum in the early morning hours. The period is the same as that of the radiation from the sun and sky. The range (max.—min.) has an annual period. It is lowest in December, rises to a maximum in May, falls to a second minimum in July, and rises again to a 600 H. MOHN. METEOROLOGY. [NORW. POL. EXP. maximum in September and October. This period is not in accordance with the annual period of the radiation from the sun and sky. I would here insert the following remark. The observations from the Fram embrace a comparatively short space of time, and the results drawn from them regarding the periods of the meteorological elements may in several instances be less trustworthy than if there had been a longer series of observa- tions at our disposal. It will not do, therefore, to draw far-reaching conclu- sions as to the connection between the different phenomena, and between those phenomena and their probable causes. Regarding the velocity of the wind it must be borne in mind as a fact in favour of the observations, that they have always been made with the same anemometer, and are not estimated wind-forces!. 1 The diurnal period of the force of the wind resulting from the CHatLEeNcer observa- tions (CHatLtencer Report, Vol. II, p. 25) is derived from the wind’s force estimated according to the Beaufort scale. Dr. Bucnan says: “With respect to the open sea, it is evident from the mean curve for the five oceans that the diurnal variation is very small, there being apparently two indistinctly marked maxima about midday and midnight respectively .... It seems probable that the line representing the true diurnal variation in the velocity of the wind is practically a uniform straight line, with the single exception of a small rise about midday, not quite amounting to a mile per hour.” The observations from the Norwegian North-Atlantic Expedition 1876—1878 (Vol. IL. Meteorology, pp. 125 to 128) which were made with hand-anemometer (in 1877 and 1878, the same instrument as that used on board the Fram) give as means for the three summers 1876—78 (88 days) in the Norwegian Sea the following result, Jv being the difference from the diurnal mean (in metres per second, smoothed): Hour Av Hour Dv 10am. +008 | 6pm +009 Noon +016 | 8 — + 0°04 2pm +015 10 — + 0:04 4 — +014 Midnight — 0°04 The diurnal period comes out very distinctly with a maximum from noon to 4 p.m, and a minimum from 4 to 5 a.m. This is the same period as that which we have found from the Fram. It does not seem improbable that the resistance presented by the waves may add to the small force of convectional currents in producing the period found. Dr. Jotrvs Hann remarks (Lehrbuch der Meteorologie, p. 390, note 7): “The nocturnal maximum of the force of the wind found at sea by ships under canvas has also been ascribed to the circumstance that the sails during the night get wet and draw better.” In the night an observer is certainly often inclined to note a higher wind force with the same velocity, than during the day, the colder air being felt more strongly at night than the warmer air is felt during the day. Results from measured wind velocities may be considered much more reliable than results from estimated wind-forces. NO. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 601 It is evident that other factors besides the radiation are instrumental in modifying the range of the diurnal period of the velocity of the wind. The most prominent factors seem to be the amount of cloud and the absolute velocity of the wind. Comparing the range (pp. 297 and 298) with a clear sky and with an overcast sky, we find that the first is less than the second in all those months in which, in the first column of the table, we have the arguments 0 and 10. In the months June to September we have no quite clear days, and the range with overcast days comes out smaller than.on half-clear days. Hence the cloudiness does not seem to have any appreciably lowering in- fluence upon the range, except in the summer months. This indicates a difference between the nature of the summer clouds and the clouds of the other seasons. The amount of cloud (p. 518; Pl. VIII) is greatest — above 8 — in the four months, June to September, and consider- ably greater than in the other months. This almost holds good for the probability of precipitation (p. 528; Pl. IX) and for the number of days with rain (p. 582). The tension or quantity of aqueous vapour has its maximum in the summer months (p. 502; Pl. VI). These facts seem to indicate that the summer clouds are thicker and denser than the clouds of the other seasons. If this be true, then the clouds must intercept the radiation from the sun in the summer months in a greater proportion than at the other seasons, and thereby cause a diminished range of the diurnal period of the velocity of the wind.! The Table on p. 302 and Pl. II, shows tbat the diurnal range of the velocity of the wind in all months and seasons is greater with a high velocity of the wind than with a low. The reason may be, as I have pointed out (p. 599), the increase of the force of the convectional currents caused by the greater resistance exerted by the rugged surface of the earth to the stronger winds of the day, than to those at night. We have seen (p. 294) that the velocity of the wind is greater in cloudy weather than with a clear sky, and (p. 304) that the greater velocity of the 1 Exact observation of the amount and density of clouds is difficult in the night and dark season. The error is presumably in the direction of relatively higher figures being noted then than in the day-time. The transparency of the clouds in the dark time is probably greater than one would suppose from the amount and density noted. 76 602 H. MOHN. METEOROLOGY. [NORW. POL. EXP. wind belongs to a cyclonic state of the weather. In cyclones the ascending currents give rise to condensation of aqueous vapour and the formation of clouds. The clouds intercept the radiation from the sun and sky, and tend to lower the range of the diurnal period of the velocity of the wind; but the stronger wind that produces the clouds, gives a greater range. The latter seems to be the more powerful, except in the summer months when the clouds are thickest and densest. The fresher and freshest winds (pp. 305 to 307, Pl. I) have a diurnal period with maximum in the day hours and minimum in the night. Putting together the means for the seasons, we obtain the following table: Winter | Spring | Summer | Autumn Diurnal range of radia- oy Cbs ols to 0014 0°436 0651 07125 Wind-velocity. m. p. s. 4-49 4:42 4°42 4°65 Amount of cloud. . . 3°76 601 8:73 6°42 Diurnal range of wind’s velocity, m.p.s. . . 0°15 061 0:36 0°42 In winter the range of radiation is small and the sky fairly clear; the range of the velocity of the wind is small. From winter to spring the range of the radiation increases rapidly, the amount of cloud increases, but the former prevails over the latter, and the range of the velocity of the wind increases. From spring to summer the range of the radiation is increasing, but the increasing amount of clouds, and their thickness and density, prevail over the radiation, and the range of the velocity of the wind decreases. From summer to autumn the range of the radiation decreases, but the wind’s velocity increases, and the sky becomes clearer; the range of the velocity of the wind increases a little. From autumn to winter the range of the radiation decreases, the wind’s velocity decreases, the sky becomes clearer, and the range of the velocity of the wind decreases. The diurnal range of the velocity of the wind generally follows the in- crease and decrease of the range of the radiation, except in summer, when No. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 603 the clouds seem to intercept the radiation in a higher degree than in the other seasons. The relatively small amount of the diurnal range of the velocity of the wind is perhaps an indication of the relatively small height to which the whole phenomenon reaches. Future polar expeditions, with a ship drifting like the Fram, could solve the question by instituting regular anemometric observa- tions from the crow’s nest. The Table on p. 471 and PI. III, shows that the diurnal period of the temperature of the air varies greatly in the different months. In the dark season the ordinary period is reversed, and we have the day colder than the night. We have found (p. 496) the explanation of this pheno- menon by means of the thermal wind-roses, the day-winds at this season being generally colder than the night-winds. Meanwhile the Table on p. 477 and Pl. IV, as also the Tables on p. 481 and Pl. V, show that we have the ordinary period with minimum at night and maximum near, or some hours after, noon in the winter and in the dark season, with an overcast sky and with stronger winds. With clear weather and feeble wind, the radiation from the earth has a tendency to produce an inversion of temperature (pp. 497, 498). But with an overcast sky and stronger winds, the lower and higher layers of the air are mingled together, and this brings the temperature of the lower layers to rise. The greater the amount of cloud, the less is the tendency to inversion; and the greater the velocity the wind, the more thorough is the mingling. This is the case in the day hours in a higher proportion than at night. In the winter and the dark season the cloudiness is greater (pp. 512, 513, and Pl. VII) and the wind stronger (p. 293, and Pl. I) at day than at night. On the other hand the average amount of cloud (p. 518, and Pl. VII) and the average velocity of the wind (p. 309, and Pl. I) is rather small in these seasons, and the resulting diurnal period comes out in accordance with that dependent on clear weather and weak winds. In the months during which the sun is above the horizon, the diurnal period of the temperature of the air has the ordinary run, with minimum in 604 H. MOHN. METEOROLOGY. [NORW. POL. EXP. the early morning hours, and maximum some hours after noon; but the range varies greatly in the different months (p. 471). The range does not increase and decrease with the diurnal range of the radiation from the sun and sky, except from March to April and from August to September. The range rises to a maximum in April, sinks to a minimum in July, reaches a smaller maximum in August, and sinks again in September. The main factor checking the radiation of the sun is the clouds, and in cloudy weather a stronger wind is also (p. 294) to be found. Putting together from the Tables on pp. 476 and 480 the range of temperature (R), and the amount of cloud and wind-velocity (v), we have the following Table. —0'25| June +0°93] July +0°45 | August +0°38 | Mean Diff. —0°95] June +1°36! July +0°56| August +0°32} Mean In spring, ten degrees of increasing cloudiness lowers the range of tempera- ture from 2°10 to 1°72 or 0°38, while in summer 55 degrees of cloudiness (10—4°5) lowers the range from 1°22 to 0°89 or 0°33. One degree of cloud- iness lowers the range as much as 0°°038 in spring and 0°060 in summer. The summer clouds seem to be thicker and denser than the spring clouds, a conclusion to which we have arrived through the discussion of the diurnal period of the velocity of the wind (p. 601). An increase in the velocity of the wind of 3 metres per second lowers the range of the temperature as much as 0°°3, both in spring and in sum- mer. The wind brings the higher layers of the air down during the day hours (p. 603) and prevents the stagnation of the air at the surface of the earth that has been cooled during the night by radiation from this surface NO. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 605 (p. 599). The stronger the wind, the more does it tend to equalize the tempera- tures of day and night, or to lower the diurnal range. In the following Table, I have put together the mean monthly values of (1) the diurnal range of the radiation of the sun and sky, r, (2) the amount of cloud, c, (8) the velocity of the wind in m. p. s., v, and (4) the diurnal range of the temperature of the air, R, for the months March to September.

The amount of cloud varies considerably, and is highest from May to September. The velocity of the wind does not vary much. The diurnal range of the temperature shows the largest variation during the months from March to September. From March to April the range of radiation increases rapidly. The amount of cloud decreases to a minimum, as does also the velocity of the wind; and all three factors are working to raise the diurnal range of the temperature. From April to May the range of radiation rises a hittle, but the amount of cloud is rapidly increasing, and also the velocity of the wind. The two last-named factors bring the range of the temperature down, notwith- standing the effect of the radiation. From May to June the range of radiation increases very little, but the amount of cloud increases one degree, and the temperature-range is lowered by the cloudiness in spite of the increasing radiation and decreasing wind- velocity. 606 H. MOHN. METEOROLOGY. [NORW. POL. EXP. From June to July the same process goes on. From July to August the range of radiation rises (the mean latitude of the Fram being relatively lowered), and the amount of cloud and the velocity of the wind decreases. The temperature-range rises, all three factors working together. From August to September the range of radiation is going down rapidly, the amount of cloud and the velocity of the wind are increasing, and all three factors cause the range of the temperature to decrease. We see that the maxima of the diurnal range of the temperature in both April and August, correspond with a higher range of the radiation, and minima of cloud and wind-velocity. The low range of the temperature in summer, particularly in July, corre- sponds to a high degree of cloudiness during a season which has hardly one clear day. The annual period of the temperature of the air has been discussed on pp. 484 and 597. In general it follows the annual period of the radiation from the sun and sky, with a certain amount of lag. The minimum of the tempe- rature falls at the beginning of February, and the maximum in the middle of July, while the radiation has its minimum and maximum at the solstices. The winter temperatures and the lowest temperatures found on the track of the Fram (pp. 483—487 and Pl. XIV and XVI) are higher than those found at the Siberian cold pole. In Siberia the low temperatures are due to calms and inversions of temperature. The soil is frozen down to a great depth?. In the cireumpolar arctic sea, calms are relatively rare (p. 283), cyclonic movements are frequent (p. 581), the upper and lower layers of air are mingled together, and the cooling down of the surface of the earth or of the polar ice is checked (p. 565 and Pl. X) by the circumstance that the underlying water has a temperature of only — 1°°6. The summer temperatures along the track of the Fram reaching above 0° are due to warmer winds. The temperature of the surface of the ice cannot become higher than 0°, and the water in the open pools scarcely higher, being enclosed by ice below and around. The thermal wind-roses (p. 495) give south- erly winds with a temperature of above 0° as the warmest in July and August, } Woerkor. Die Klimate der Erde. Kap. 23. No. 17.] THE METEOROLOGICAL PERIODS IN THE ARCTIC SEA. 607 and the windward side of the wind-rose (p. 285) indicates that such south- erly to south-westerly winds are most prevalent in July. The temperatures above zero are imported by the winds. The diurnal period of the tension of vapour is very distinctly developed, even in the winter and the dark season (p. 501 and Pl. VI). The range generally follows that of the temperature. It is very small in the dark season, and rises, even in spring when it is greatest, only to 02 mm. The period has only one maximum, after noon, as sea-board stations generally have in temperate latitudes. The diurnal ascending currents are too weak to carry the vapours upwards at a rate sufficient to produce a secondary minimum at the warmest time of the day. At might the vapours are occluded by the snowy surface. The annual period of the tension of vapour (p. 502 and PI. III) generally follows the corresponding period of the temperature of the air. It has its maximum in July, like that of the air; but the minimum of the tension falls in January, while that of the temperature falls later. The whole range is only 43 mm. The diurnal period of the relative humidity (pp. 505 to 507, and Pl. VII) does not present any particular features. It is very inconsiderable in the winter months and the dark season, and its range rises in summer only to 2°5 per cent. The annual period of the relative humidity has its maximum in July (p. 508, and Pl. VII) and minimum in October. Its march is not very regular. The great humidity in the summer months is most prominent. The diurnal period of the amount of cloud (pp. 512 to 513, and Pl. VII) shows a greater cloudiness in the day than in the night, in all seasons, and, with some exceptions, with strong than with feeble winds (p. 517, and Pls Vi): In winter there is no period with feeble winds, but a rather well- developed period with fresh winds. These winds being cyclonic (p. 304), they 608 H. MOHN. METEOROLOGY. [NORW. POL. EXP. are accompanied by ascensional movements of the air, causing condensation of aqueous vapours and the formation of clouds. The wind (Pl. II) being fresher in the day than in the night, there is a probability of a similar period in the amount of cloud. The winter is the season in which there is the greatest number of cyclones (p. 581). In general we find the range of the amount of cloud greater with fresh winds than with feeble winds; but in summer the reverse is the case, and in this season the diurnal range of the other elements is small with fresh winds. The annual period of the amount of cloud is very distinctly developed with a minimum in December to January and a maximum in July to August (p. 518, and Pl. VIII). The same holds good for the number of days with an overcast sky. The probability of precipitation is generally a little greater in the day than in the night (p. 527, and Pl. IX) and its diurnal period corresponds with that of the temperature, the tension of vapour, the velocity of the wind, and the amount of cloud. The annual period of the probability of precipitation comes out very well (p. 528, and Pl. TX) with maximum in summer and minimum in winter, similar to the periods of temperature, tension of vapour, and amount of cloud. Corre- sponding to this, there is the annual period of the number of days with precipitation (p. 531, and Pl. IX). The number of hours of precipitation in a day of precipitation (p. 534, and Pl. IX) is generally greatest in winter and least in summer. The number of observations are too small to show a regular annual period. The probability of fog (p. 536, and Pl. [X) has a diurnal period in sum- mer, which is the reverse of that of the temperature. Fog forms more easily at night than in the day. The annual period of fog (p. 537, and Pl. IX) is very regular. No fogs in winter, and maximum of frequency in July. NO. 17.] THE SLEDGE-EXPEDITION. 609 THE SLEDGE-EXPEDITION. During Professor Nansen’s and Lieut. (now Captain) Jonansen’s sledge- expedition and wintering on Franz Joseph’s Land in 1895—96, meteorological observations were made almost every day, comprising wind, atmospheric pres- sure, temperature of the air, amount and forms of cloud, and weather. The direction of the wind was noted by compass, and its velocity estimated in metres per second. This estimation was based upon the practice which the observers had gained on board the Fram when using the hand anemo- meter mentioned on p. 3. For the observation of atmospheric pressure the expedition had two pocket aneroids. The aneroid Hicks was divided into inches and the aneroid Cary No. 4387 into millimetres. Before leaving the Fram, the aneroids were compared with the mercury- barometers on board, Adie No. 763 and 764. The heights of the mercury- barometers were reduced to 0°, to the standard barometer and to standard gravity. Seventeen comparisons made from the 22"¢ to 25t February, 1895, gave the result, Correction for Hicks = — 2:0 mm. — - Cary = +50 - In neither of the aneroids did the correction show any appreciable varia- tion with pressure. The mean error of the correction found by one comparison was + 0°16 mm. for each aneroid. The mean error of the pressure determined by the mercury barometers is about + 0°05 mm. This gives the mean error of a duly corrected reading of any of the aneroids equal to 77 610 H. MOHN. METEOROLOGY. [NORW. POL. EXP. + 7 0-162—0:05? = + 0:15 mm. At the beginning of the sledge-journey in the middle of March, 1895, Cary read 7 mm. lower than Hicks. The difference between the aneroids had risen during the latter days of April to nearly 8 mm., and in the 3t¢ week of May to a little above 8 mm. On the 29% May, Cary was found to read only 2°38 mm. lower than Hicks, on the 30% at 7 a.m. 2°1 mm. lower, and on the same day at 7.30 p.m. Hicks was reading 20 mm. lower than Cary. The difference increased on the 1** June to 21 mm. and remained during June between 20 and 26 mm. Hicks was carried in the pocket and Cary in the kayak on the sledge. On the 30% May, Prof. Nansen remarks “Hicks probably got a shock in my pocket.” As seen from the above remarks, Hicks must evidently have commenced to alter its correction on the 29 May. Hicks was read simultaneously with Cary up to the 25 June and only 8 times subsequently, in August, October, November, January and February. The difference between the aneroids was then from 21 to 25 mm. In June and July, 1896, at Cape Flora, Hicks was found reading 20 mm. lower than Cary. With the probable corrections for Cary given below, we obtain for Hicks the following corrections: June 1st, + 27:0 mm.; June 8, -++ 27°6 mm.; June 9th, + 30-9 mm.; June 14%, + 31°7 mm.; June 17, + 32:2 mm.; August 8 and 10%, + 29:7 mm.; October 345*, + 31°6 mm.; November 30, + 33°3mm.; January 7", +33°0 mm.; January 8", + 32:4 mm.; and February 2"4,-++- 34:3 mm. In June, 1896, at Cape Flora the correction was found to be + 31°0 mm. Up to the 27 May, 1895, only Hicks was read, with only a few excep- tions, when both aneroids were read. After that date, the readings of Hicks were not considered very trustworthy, and only the readings of Cary were used for the determination of atmospheric pressure. When Prof. Nansen and his comrade had reached Mr. Jackson’s Station at Elmwood, Cape Flora, Franz Joseph’s Land, the two aneroids were com- pared there with the marine barometer Adie B. T. 655. The readings of this barometer were reduced to standard temperature, and to the standard barometer by means of the Kew-corrections given. The resulting readings in inches were converted into millimetres and reduced to standard gravity. The result of 75 comparisons from June 20 to July 10*, 1896, was, NO. 17.] THE SLEDGE-EXPEDITION. 611 Correction of Hicks = + 31:0 mm. MEH = + 0°38 mm. -- - Cary =+ 97mm. — =+ 0°48 mm. In February, 1895, on board the Fram, Cary’s correction was + 5:0 mm., and in June, 1896, + 9°7 mm. ‘This gives an increase of the correction of 4°7 mm. during 15 months. The comparisons with Hicks during the journey and the stay at the winter-hut are incapable of giving any information as to the corrections of Cary. It is not probable that the change of Cary’s correc- tion has been uniform during the 15 months. Aneroids are most liable to change their correction when moved or shaken more or less violently, and to keep their correction unchanged when kept at rest. Starting from this consideration, I have assumed that Cary has had its correction increased during the arduous journey over the rugged ice, when it lay in a kayak on the sledge, and that it was unchanged, or very little changed, during the days when it was not exposed to violent motions. Such time are the resting of the expedition in the “Camp of Longing” from July 1s* to 20%, 1895, and the stay at the winter-hut from August 23™, 1895, to May 19%, 1896. The journey from the winter-hut to Cape Flora, May 19% to June 16%, 1896, was made chiefly by kayak and this mode of transportation would hardly have any appreciable influence upon the correction of the aneroid. From the beginning of the sledge-journey in March, 1895, up to the 27 May of that year, I have reckoned with a constant correction of —2 mm. for Hicks, which gives a slow rising of the correction for Cary, amounting to one milli- metre. Between May 27'* and July 1%* I have assumed the correction for Cary to be rising from +62 mm. to 8 mm. From July 1% to 20%, the correction has been taken constant, +8 mm., in the “Camp of Longing”. From July 20% to August 23°¢, the adopted correction is rising from + 8 mm. to 9°7 mm., and for all the rest of the journey the correction is the + 9°7 mm. found at Cape Flora. The rate of change from May 27 to July 1%* is 1-64 mm. per month and from July 20% to August 23"¢, 1:55 mm. per month. This is practically the same rate during the two parts of the difficult sledge- journeying. Professor Nansen agrees with me in this settling of the question of the corrections of the aneroids. As will be shown further on, the adopted values accord well with the atmospheric pressure found on the Fram and at Cape Flora. 612 H. MOHN. METEOROLOGY. [NORW. POL. EXP. The winter-hut lay about 7 or 8 metres above the level of the sea. The observations made from August 26%, 1895, to May 19%, 1896, at or in the hut, have been reduced to sea-level by adding 0°7 mm. The uncertainty attaching to the corrections of the aneroids has induced me to give in an extra column the direct readings of these instruments. For the observation of the temperature of the air the expedition had 5 thermometers. Three of these were mercury sling-thermometers, No. 14, No. 18 and No. 20, and two minimum registering thermometers, Toluol B and Metaxylol C. The zero of all the 5 thermometers had been determined in April 1893, at the Meteorological Institute in Christiania. On board the Fram the zero of No. 20 was verified in February and in April, 1894, and the two index-thermometers were compared at low temperatures, — 30° to — 40°, with the standard thermometer, Tonnelot No. 11002 (see p. 11), whose zero remained unaltered during the expedition. The errors of the mercury sling-thermometers at low temperatures may be assumed equal to the error of zero. They were made by SoperBere of Stockholm, and we have seen (p. 13) that the error of SopERBerG’s psychro- meter-thermometers are nearly nil between 0° and — 30°. Toluol B was compared in January and February, 1894, and in January, 1895, with Tonnelot 11002, from — 23° to — 45°. The results of the two series agree very well. Metaxylol C was compared with Tonnelot 11002 in January, 1894, from — 27° to — 42’. The corrections applied to the observed temperatures are Mercury Th.s. Toluol B. Metaxylol C.

During the night’ or during the time when we rested, the thermometer was generally placed on the deck of the canvas kayak, while the sun was low (during the first week), and subsequently on the surface of the ice, well protected against the direct sun-rays. During the former period the temperature was simply read off without swinging the thermometer; during the latter the temperature was taken with a sling-thermometer, and after the last mercury sling-thermometer was broken (June 28*), with Toluol B. At our winter-hut, on the night of October 6, 1895, the minimum- thermometer Toluol B was stolen by the foxes, and after that date the other minimum-thermometer, Metaxylol C, was used for all observations of tempera- ture. The same thermometer was also used for all observations during the sledge-journey from our winter-hut to Cape Flora in the spring of 1896. As, however, it was the only thermometer we had left, I did not then run the risk of swinging it, and it was therefore only suspended in the shade. At our winter-hut, after the sun had disappeared, the observations were taken with the minimum-thermometer, Metaxylol C, freely suspended in the air at a height of about 1°6 metres above the ground. The instrument was attached to one of our sledges which was raised on end, first against the wall of our hut and afterwards against a big stone in the neighbourhood. We had no lantern for the reading of the thermometer, and I tried in vain to construct one which would not burn more oil than we could afford to use. But our eyes of course became gradually trained to see in the dark, and even in mid-winter, with no moonlight, there was so much light (star-light?) reflected from the snow, that the column of the darkly-coloured metaxylol was dimly 614 H. MOHN. METEOROLOGY. [NoRW. POL. EXP. visible, and also the figures of the thermometer-scale, but not the division- marks. By estimating the distance between the figures, the degrees could nevertheless be read off fairly well, but not the tenths of degrees. I do not therefore consider it advisable to pay too much attention to the temperature- observations during the darkest time, December and January, when the moon was not above the horizon; but as soon as she appeared, the thermometer- scale could be seen better, and with a full moon it could be read off very accurately. We had the moon above the horizon during 24 hours in 1895 from October 8. to November 12.

On February 3'¢, 1896, I discovered that the column of Metaxylol C had become broken, and the upper portion indicated — 5*8, while the thermometer indicated an air-temperature of — 17° after the separated portions of the column had been united (by heating the bulb with the hand and shaking). I write in my diary, that this breaking of the column had probably occurred on January 8", 1896, when the wind had carried away the sledge, to which the thermometer was attached, for some distance, and the breaking of the column might have been caused then by the probable violent shaking of the instrument. It seems somewhat difficult to understand how it could have happened later, as the thermometer was then the whole time safely suspended. When I discovered the accident on February 3'¢ there was an interval equal to 11°2 between the top of the broken off metaxylol and that of the rest of the column, and this interval appeared to remain unaltered during the rise or fall of the column. If this be correct, all readings between January 8 and February 3'4, 1896, ought consequently to be reduced by a correction of — 11°2; but it is hardly probable that the error has remained the same throughout the time, even if it actually occurred on January 8", which is also doubtful. It is thus to be understood that the temperatures given for this period are not trustworthy.” (Frmtsor Nansen). The error in the thermometer Metaxylol C found by Prof. NaNseN on the 5° February, 1896, can hardly have been caused by the accident on NO. 17.] THE SLEDGE-EXPEDITION. 615 January 8". The ensuing correction of —11°2 would give temperatures below — 50° in the days from January 11 to 15". Prof. Nansen does not think it probable that such low temperatures have occurred, and the obser- vations from the Fram for the same days (p. 457) give temperatures of from — 45° to — 49°, whereas otherwise the Fram-temperatures are always lower than those observed at the winter-hut. In this dilemma, I conceived that a comparison between the temperatures observed at the winter-hut and those of Cape Flora might give an indication of the time when the thermometer Metaxylol C had changed its correction. I wrote to Dr. W. N. Suaw, F.R.S., Secretary of the Meteorological Office, London, and asked him if it were possible to obtain copies of the tempera- tures observed at Mr. Jackson’s station at Cape Flora, at 8 a.m. and 8 p.m. from January 8 to February 3*¢, 1896. This application was answered in the most friendly way by Dr. Saaw, for which I am most grateful to him. Plotting the temperature-observations from the Fram, from the winter-hut, and from Cape Flora, I found that those from the Fram were lowest. The winter- hut, from January 8 to January 21st, had sometimes a lower and sometimes a higher temperature than Cape Flora. But from January 23°? to February 24 the temperatures read off at the winter-hut were decidedly lower than those from Cape Flora, while their courses ran remarkably parallel. The mean difference was 11°2C, a figure exactly equal to the correction for Metaxylol C found on the 23'¢ February by Prof. Nansen. With this correction, and the corrections otherwise found, the temperatures read at the winter-hut, from January 23'¢ to February 2°¢ are given in the Tables of observation. 4 The amount of Cloud is given from the scale 0 (clear) to 10 (overcast).

MOHN. METEOROLOGY. [NORW. POL. EXP. Professor Nansen’s observations at the winter-hut may, I believe, be of service in furnishing data for the climatology of Franz Joseph’s Land. The observations certainly lack the regularity of a normal meteorological station, and as we have seen, there have been some difficulties about the determina- tion of the errors of the instruments; but the observations have been faith- fully made and on a spot of the earth not previously visited by man for any length of time. I have therefore thought it well worth while to work out the following climatological Table. The mean pressure for each day was computed as the mean of the daily observations. The amount of cloud, and velocity of the wind for each month are the direct means of the observations in the Table above. The temperature-observations of the Table were plotted on ruled paper, and a curve drawn through the points, regard being taken to the noted minimum-temperatures and the most probable daily course of the temperature. From this curve the temperature was taken out for every day at 2a.m., 8a. m., 2p.m. and 8 p.m. and from them the monthly mean was computed as their direct mean. The frequency of the winds from the 8 points, and of Calms, is given as a percentage of the total number of wind-observations in each month. NANSEN’S WINTER-HUT — FRANZ JOSEPH’S LAND. Lat. 81°13’ N.

The temperature of the air was above 0° on the 9* and the 12' Sep- tember and below — 40° on the 1**, 2° and 11 January. The situation of the winter-hut under a steep cliff facing SW, probably gives many of the winds from N, NE and E a character of a Fohn, which may have a certain influence in making the mean temperature higher than in a more open situation. This seems particularly to be the case in November, January, February and April with their frequent winds from N, NE and E. The precipitation fell as snow, except on the 3°? and the 12 September, when some rain fell. The windward side of the wind-rose lay thus (see p. 285): 652 H. MOHN. METEOROLOGY. [NORW. POL. EXP. The resultant direction and its amount are shown in the last line. The prevailing winds are chiefly easterly. The station lay on the north side of the Atlantic barometrical trough (p. 572). The mean velocity of the wind is estimated a little less than the measured velocity at the Fram (p. 309). Gales with estimated velocities of 15 metres per second and upwards to 18 metres were experienced on two days in December, on two days in January, and on one day in February. The highest velocity measured at the Fram was 18 m.p.s. (p. 310). In order to see how the observations at the winter-hut stand in relation to those of the Fram and at Cape Flora! (Lat. 78°55‘ N; Long. 48°40’ E), I have put together the following Table. Sept. | Oct. | Nov. | Dec. | Jan. | Feb. | Mar. | Apr.

MOHN. METEOROLOGY. [NORW. POL. EXP. OBSERVATIONS IN EAST-SPITZBERGEN 1894—95 made by Mr. M. Exrott. In the summer of 1894 Mr. Martin Exrotit made a voyage with his schooner, Willem Barendtz from Norway to Spitzbergen, and wintered on the east side of the Storfjord in a place situated in latitude 77°30’ N and 20°55’ E, from August, 1894, to July, 1895. Meteorological observations were made on board from the beginning to the end of the voyage. During the winter another station was established at the ANDERson’s Istanp in the Storfjord, lat. 78°20’, long. 20° 44’ E where observations of temperature, wind and weather were made. The observations have been worked up by the Norwegian Meteorological Institute. The result for the winter stations are given in the following Tables.1 They may be useful for comparison with those from Cape Flora and from the Fram. The observations of the atmospheric pressure were made with an aneroid, whose corrections were found by means of observations made on the coast of Norway both at the start and at the return of the expedition, and com- pared with the observations made simultaneously at the coast-stations of the Norwegian Meteorological Institute. The Table gives the corrected values. The temperature of the air was observed with mercury and spirit centi- grade thermometers. The amount of cloud is given according to the scale, 0 = clear and 4 = overcast. 1 The daily observations are deposited at the Norwegian Meteorological Institute, and copies of them may be had on application.
