The reductions for temperature, constant error, and gravity were made with two decimals of a millimetre. In the Tables, the reduced observations of the pressure are given to the nearest tenth of a millimetre. The Expedition had two Barographs made by RICHARD in Paris. One of them stood in the cabin, and continually registered the pressure of the atmosphere. The clock-work was wound up and the paper changed every Monday. The scale was 1 mm. = 1 mm. Further particulars will be found in the chapter on the Pressure of the Air. TEMPERATURE OF THE AIR. THERMOMETERS. The expedition started with the following thermometers, destined for meteorological observations : I. 8 mercury thermometers, made by SODERBERG in Stockholm, divided into 0'2 of a degree on paper scales hermetically inclosed, and ranging from — 40° to + 40° C. Spherical bulbs. NO. 17.] THERMOMETERS. 11 They were compared in April, 1893, with the standard thermometer of the Norwegian Meteorological Institute, whose corrections to the hydrogen thermometer are known. The results of these comparisons were as follows: SODERBERG Correction at No. 0° 3° 9° 12° 20° 30° 105 +0-20° +0-12° -0-01° -0-07° -0'12° — 0'13° 106 +0-20 +0-12 0-00 —0-02 -0-12 -0'13 107 +0-20 +0-12 0-00 -0-07 -0'12 -0'13 109 +0-20 +0-12 -0-05 -0*07 -0'15 — 0'15 111 +0-20 +0-12 —0-05 -0-07 -0'15 -0'16 112 +0-20 +0-17 -0-02 -0-07 -0'15 —0*18 114 +0-20 +0-14 -0-02 -0-07 -0'12 — O'lO 118 +0-20 +0-14 —0-02 —0-02 -O'll -0*13 It was intimated that the zero-points would probably rise with time; and it will be seen by comparison with the adopted corrections, that this has also been the case. Unhappily not one of these thermometers has been brought back in a sufficiently unchanged state to allow of these corrections being verified. The determination of the zero-points on the voyage was attended with difficulty, owing to the fact that snow or ice that did not contain salt was almost unobtainable. The most trustworthy observations were made with hoar-frost collected on board. II. 4 toluol thermometers made by TONWELOT in Paris, the stem divided into whole degrees C., cylindrical bulbs. They were compared at the Bureau International des Poids et Mesures (Sevres) at low temperatures in May, 1892, and their zero-points were determined at the Meteorological Institute in Chris- tiania in April, 1893. The corrections to the hydrogen thermometer were as follows: TONNELOT Correction at No. 0° —23° —30° —52° —53° —54° —65° 4992 +0-20° —0-02° -0'24° 4993 +0-20 +0-07 +0-03° 11001 +0-20 +0-08° +0-01° +0-07° 11002 +0-20 —0-16 —0-09 — 0'15 12 H.

The correction at 0° of No. 4993 was found to be, on board, April 12, 1894, O'O in Ghristiania, March, 1897, -)- 0'3 The correction at 0° of No. 11001 was found to be, on board, October, 1893, + 0'25°. Only No. 4993 was brought back. All the zero-points may be regarded as having undergone no appreciable change during the voyage. The Tonnelot thermometers, corrected for their errors, have been used as standards in the comparisons that were made on the voyage, for finding the corrections of the other thermometers for temperatures below — 20°. These comparisons were only made in the air, the thermometers being suspended in the thermometer-screen. III. 15 mercury sling- thermometers Nos. 11 to 25, made by SODERBERG. Their stems were divided into whole degrees C., and they had cylindrical bulbs. They were compared in Christiania in 1893, and their zero-points occasionally verified during the voyage. IV. 10 spirit sling-thermometers, Nos. 1 — 10, made by SODERBERG, to which the same remarks apply as for III. It was observed that the fluid became thick at — 40°. V. A number of spirit minimum (index) thermometers. Their correc- tions were determined every day that they were in use, by comparison of the reading of the top of the spirit-column with the thermometer for the air-temperature. VI. 2 mercury maximum thermometers. They were compared in Chris- tiania in May, 1893, and the comparisons made on the voyage showed that they kept their corrections in a very satisfactory manner. VII. 2 sets of registering thermographs from RICHARD in Paris, specially made for the Expedition. The clock-work turned the drum round in a week, and the registered temperatures could be read to + 0-1°C. The thermometers used as dry and wet-bulb thermometers for observing the temperature of the air and determining its humidity, were some of those described above under I and II.

This was done as far as possible in the shade, and on a spot that was free from radiating or conducted heat from any part of the ship. From the day when the ship became fast in the polar ice, the thermo- NO. 17.] HYGROMETERS. 15 meters and the thermograph, as well as the hygrometers, were placed in a spacious thermometer-screen of the model of the Stevenson Screen, made of wood, and resting upon four wooden feet fastened into the ice below. The bulbs of the thermometers were at a height of about 1'2 metres above the ground. When the sun was above the horizon, an extra screen kept the thermometer-screen in shadow. The few instances in which the adjustment of the extra screen was forgotten, are noted in the remarks. As there was generally a wind blowing, the thermometers were well ventilated. The screen had no bottom; this was necessary in order to prevent it from being filled with driving snow. The observers remark in some cases, in very cold weather, that the thermometers showed a litlle lower shortly after the opening of the door of the screen than before. This may be an effect of radiation of heat from the thermometers, and an indication of the necessity of having them protected from radiation by means of the screen. The first reading of the thermometers has been taken as the true reading. On several occasions the thermometer-screen was in danger of being carried away by the screwing of the ice, and had to be taken on board. Such cases have been noted in the remarks. HUMIDITY OF THE AIR. HYGROMETERS. The humidity of the air was determined from observations made with a psychrometer and a hair-hygrometer. The SODERBERG thermometers mentioned above (page 13) served as dry and wet-bulb thermometers. When the ship was at sea, the thermometers were rotated in the whirling machine. During the drift of the Fram, the thermometers stood in the thermometer-screen (described above). From the corrected readings of the dry and wet-bulb thermometer, the vapour-tension and the relative humidity were computed by means of JELINEK'S Psychrometrical Tables. When the wet-bulb thermometer was below zero, its reading has been corrected, in accordance with EKHOLM'S recommendation, in the following manner before using the psychrometer tables. From To Corr. -01° -1-1° — OT — 1-3 — 2-2 — 0-2 16 H. MOHN. METEOROLOGY. [NORW. POL. EXP. From To Corr. -2-4 -33 — 0-3 — 3-5 — 4-4 — 0-4 below -4-4 — 0-5. In this manner, the observations in which the wet-bulb thermometer was below 0° and above — 10° are employed as well qualified to give trustworthy results. The Expedition had two hair-hygrometers, designated in the Meteorolo- gical Journal as I and II. They were placed in the thermometer-screen close to the psychrometer, and were read constantly during the time in which the temperature of the air was below zero. The values found for the relative humidity, from the observations of the psychrometer, when the wet-bulb thermometer stood between 0° and — 10°, served for finding the corrections of the hair-hygrometer. The first autumn was an exception to this rule. On October 11, 1893, the screen was set out on the ice with its thermometers and a hair- hygrometer. Before this date, no observations of the hair-hygrometer had been made, but only psychrometer-observations. These, from the 2nd October, were taken in temperatures generally lower than — 10°. In order to render them serviceable for the determination of the humidity of the air, I had recourse to the direct comparisons between the psychrometer and the hygrometer made during the spring and autumn of 1894. The result of these comparisons was that the psychrometer-readings computed in the above- named manner from the psychrometrical tables, gave too low values for the humidity. The corrections for the psychrometrical relative humidity found were, at — 10° Corr. = 0, at — 20° Gorr. = + 14 %, and at — 30° Corr. = + 26 %, practically proportional to the temperature. The values for the humidity entered in the Tables for the days from the 2nd to the llth October, 1893, are computed by means of these corrections. The corrections found for the readings of the hair-hygrometers by means of psychrometrical observations (ps), or by keeping them in saturated air (sat), were as follows: Hygrometer I, from October, 1893, to March, 1895. 1893.

In the winter, the hygrometers were often covered with hoar-frost, and it was necessary to have them thawed and cleaned. This operation did not seem to affect their reading in any appreciable degree. When a hygrometer, after having been cleaned, was brought out into the open air, it sometimes showed too low, but soon attained its true working position, and the reading 18 H. MOHN. METEOROLOGY. [NORW. POL. EXP. was never noted until this was reached. The hygrometer in the screen served as a check on the other, when the latter was set out after being cleaned or verified. The comparisons made between the psychrometer and the hygrometer give a mean error of comparison of from 1 to 2 %. For the winter, the error of a single adopted value of the relative humidity is estimated to be from 3 % to 5%. The vapour-tension (or absolute humidity) has been computed (1) from the psychrometer-observations and JELINEK'S Tables, when the temperature of the wet-bulb thermometer was above — 10°; from 0° to — 10° by EKHOLM'S rule. (2) from the corrected readings of the hair-hygrometer.

For temperatures from — 40° to — 55° the following auxiliary table was computed by the formula1 where A = 4'57 mm, ft = 0'03134, a0 = 0-003667, and t = temperature of the air. Temp, of Air. Max.

The values given for the relative humidity may be uncertain to the extent of ± 5 %. The influence of such an error upon the deduced value of the vapour-tension is trifling, and practically of no importance. The follow- 1 0. J. BROCH. Tension de la vapeur d'eau p. A. 30.

The Relative Humidity has been computed (1) from the psychrometrical observations in conjunction with the vapour- tension. (2) from the readings of the hair-hygrometer. From October, 1893, to March 17, 1894, only Hygrometer I. was observed. From the latter date to the 20th August, 1896, both hygrometers were as a rule observed, and the mean of their corrected readings — provided their corrections were considered trustworthy — adopted for the relative humidity. The values of the relative humidity computed from the psychrometrical observations have been checked throughout by the simultaneous observations of one or two hygrometers. The mean error of a single determination of the relative humidity entered in the Tables, resulting from the different comparisons of simultaneous ob- servations of two instruments, may be taken as hardly greater than 5 °/o. 20 H.

Thin clouds are indicated by ° as exponent, very thick clouds by 2 as exponent. The forms of the clouds were noted in conformance with HOWARD'S definition. The International Cloud Atlas was not published at the time of the departure of the Expedition in 1893. The drift of the clouds is given by noting the point of the compass from which they came. PRECIPITATION. STATE OF THE SKY. The Expedition had a rain-gauge and a snow-gauge of the same pattern as those of the Norwegian Meteorological Institute. The rain-gauge has a cir- cular, and the snow-gauge a square, receiving surface of 225 square centi- metres. The gauges were placed on board or on the ice. The amount of precipitation collected in the gauges was always very small, and cannot be regarded as a true measure of the quantity of liquid or frozen moisture that fell upon the ground. It is a well-established fact that it is impossible with ordinary gauges to obtain the full amount of rain, and particularly of snow, measured in the conditions prevailing in arctic regions. The amount of pre- cipitation noted has therefore not been entered in the Tables in a special column, but has been transferred to the remarks and to a special Table.

THE STATE OF THE SEA. The direction of the motion of the sea was noted by the compass in the same manner as the wind, and has been reduced to the true meridian. The Sea-Disturbance was estimated in accordance with the following scale: 0 = dead calm. 4 = moderate. 7 = high 1 = very smooth. 5 = rather rough. 8 = very high. 2 = smooth. 6 = rough. 9 = tremendous. 3 = slight. The state of the sea has not been entered in the Tables, but referred to a special chapter. THE HOURS OF OBSERVATION are local time, civil date. THE POSITION OF THE SHIP. The latitude and longitude (Greenwich Mer.) for each hour of observation given in the Tables have been taken from charts showing the exact route of the Fram from Varde to the New" Siberian Islands, (cf. vol. Ill, No. 9, Pis. VII— IX) and from the astronomical observations published by Prof. GEELMTJYDEN in vol. II, No. 6 of this work. The positions between the places determined directly by astronomical observations have been computed by direct linear interpolation. 22 H. MOHN. METEOROLOGY. [NORW. POL. EXP.

"Blue sky" in the remarks below the Tables of Observations signifies "Water-sky" or reflection from open water. RESULTS. R rom 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. The following Table shows for each month of the drift, the mean, the highest, and the lowest latitude and likewise the mean, the greatest, and the least longitude, taken from the positions of the Fram each noon (local time). 252 H.

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. DI RECTION. 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 NbE, NEbN, NEbE etc. were distributed evenly, each with half their amount, among the adjacent 16 points N, NNE, NE etc. The result of this tabulation is given in the following Tables of Wind-Frequency. 256 H.

MOHN. METEOROLOGY. [NORW. POL. EXP. WIND-DIRECTION. DIURNAL PERIOD. In order to find the diurnal period of the wind's direction, it is necessary to have a long series of observations for discussion. 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. OCT.-FEBR. 15 MONTHS. 2a.m. 4a.m. 6a.m. 8a.m. 10a.m. Noon 2p.m. 4p.m. 6p.m. 8p.m. 10p.m. Mnt.

MOHN. METEOROLOGY. [NORW. POL. EXP. 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 nshift" the shifting of the direction of the wind, a -(- meaning a shifting with the sun (veering), and a — against the sun (backing) 1).

MOHN. METEOROLOGY. [NORW. POL. EXP. In the dark season the wind shifts generally against the sun. Only from 4 p. m. to 6 p. m. and from 8 p. m. to 10 p. m. does it veer with the sun. 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. to 1 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 1 p. m., and the South component over the North from 1 p. m. to 3 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.

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 following Table gives the number of observed winds referred to 16 points of the compass, true direction, the number of calms noted, and the sum of the observations made, for each month of the voyage of the Fram from the 1st October, 1893, to the 19th August, 1896. The maxima and minima are dis- tinguished by heavier type. 280 H. MOHN. METEOROLOGY. [NORW. POL. EXP. WIND-FREQUENCY.

There is apparently a change in the direction of the prevailing winds along the track of the Fram. 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. METEOROLOGY. [NORW. POL. EXP. THE CONSTANCY AND CHANGE OF THE DIRECTION OF THE WINDS. 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 (3) backing, and reducing the number of cases to 100, we obtain the following Table. p.ct. p.ct. 1. 2. 3. 1. 2. 3. 43 26 31 July 1894 52 23 25 95 50 19 31 95 38 31 31 96 51 22 27 % 33 27 40 February 1894 38 26 36 August 1894 43 29 28 95 43 28 29 95 38 30 32 % 43 25 32 March 1894 . . . 37 22 41 September 1894 45 28 27 95 .... 55 23 22 95 37 31 32 % 46 30 24 April 1894 53 22 25 October 1893 49 27 24 95 51 24 25 94 51 21 28 94 49 27 24 95 38 28 34 May 1894 59 19 22 November 1893 47 26 27 95 51 20 29 94 .... 44 27 29 96 40 25 35 95 46 25 29 June 1894 40 32 28 December 1893 . . . 60 25 15 95 41 24 35 94 58 20 22 % 38 29 33 95 51 20 29 Taking the means for the months, seasons and year, we obtain NO. 17.] WIND. 287 1. 2. 3.

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 h'nd 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. 288 H.

Months Year Considering the possibility that the diurnal period of the velocity of the wind might be different with different states of the sky, I have computed the mean values of the velocity for the different hours in each month separately for the days with clear sky (amount of cloud 0) and for the days with the sky overcast (amount of cloud 10). 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.

We see from the Table, that the velocity of the wind is on the whole obviously greater with cloudy weather than with a clear sky. 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.

September forms an exception, but this month pre- sents no clear days, and only a few days with a small amount of cloud. 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 cm. = 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 for a 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 4'5 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.

PI. II (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 2 a. 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. [NOKW. 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. The result is given in the following Table. Frequency per cent. N NE E SE S SW W NW Calm.

Among the weaker winds, East is most, and West least frequent. Among the stronger winds, South-East is most, and South-West least frequent. October, strongest ESE, weakest W, NW and N. 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 E; for the sunny season, strongest wind E, 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. This Table gives the number of observed winds with a velocity of 10 metres per second and upwards, reduced to bihourly daily observations during the three years from September, 1893, to August, 1896. 2 a.m. 4a.m. 6 a.m. 8a.m. 10a.m. Noon 2p.m. 4p.m. 6p.m. 8p.m. 10p.m. Mnt.

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 X 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. * The following Table shows the numbers thus obtained. 1 The exact reduction is not one half, but 0.5 sec. ltl/t°, or 0-5098. 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. 312 H MOHN. METEOROLOGY. [NORW. POL.

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 HOHWU 639 (Vol. II, No. 6, XIX), from which the exact local hour was computed from Prof. GEELMUYDEN'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 tor 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, 18%. 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 1 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, i. e. hourly corr. mean minus monthly mean, for each of the 24 hours.

The angular constant At lies about 160° (max. hour 7h 20m p. m.) except in September. Its range al 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 Az oscillates around 297° (max. hour 5h 5m). The general rule, maximum at 10h and minimum at 4h, is here nearly reversed. The value of az 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 a2 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.

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 Hohwil 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, H., 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 27th, 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 4th 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. G°. 1893. OCTOBER.

The tables give the mean temperature of each day, being the mean of the 24-hourly temperatures in the horizontal rows, and the monthly means for each hour being the means of 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 hori- zontal row of means. The hourly means have been corrected in the usual way1 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 temperatures are given in the tables as "Corr." The last horizontal row gives the difference, "hourly corr. mean minus monthly mean", headed D. f. m. (Difference from mean) for each of the 24 hours. This series represents the diurnal period as it is educed from the observations. 1 H. Wild. Die Temperaturverhaltnisse des Russischen Reiches.

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.

METEOROLOGY. [NORW. POL. EXP. October has the lowest minimum at 7 a. m. and the highest maximum at from 1 to 2 a. m. A second maximum occurs at 3 p. m. and a third at 10 a. m. In general the day is colder than the night. November and January have the minimum in the afternoon, and the maximum in the morning hours. December has a lowest minimum at 9 a. m. and a highest maximum at 1 — 2 a. m. There is a second maximum at 2 p. m. The day is colder than the night. February has two minima, at 1 p. m. and at 9 p. m., a highest maximum at 7 a. m., and a second maximum at 5 p. m. The day is colder than the night. Taking the means of D. f. m. for the 12 months in which the sun was entirely below the horizon (Oct. 1895, Nov. 1893, 94, 95, Dec. 1893, 94, 95, Jan. 1894, 95, 96, Febr. 1895, 96) we obtain lh 2h 3h 4h 5h 6h 7U 8h 9H 10* 11* lit a. m. p. m. 0-20 -0-19 0-19 -0-22 0-18 -0-225 0-18 -0-20 0-18 -0-15 0-15 -o-ii 0-11 -0'07 0-04 -0-03 -0-05 0-02 -O'll 0-11 -0-15 0-16 -0-17 0-195 Minimum — 0'°23 at 2h18mp. m.

The march of the temperature during 24 hours comes out very regularly, and with a single period. Day is colder than night. The range is small, but distinctly defined both in amount and direction. (PL III. 1 cm. = 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 radiation from the twilight may have some effect, and this must tend in the same direction as the radiation of the sun. A period with the day colder than the night must have a different origin. We have seen (p. 278) that in the dark season the north component of the wind's frequency exceeds the south component uninterruptedly from 7 a. m. to 8 p. m. The wind-roses for the temperature of the air show, as will be found later, that in the dark season the northerly winds are colder than the southerly winds. It seems NO. 17.] TEMPERATURE OF THE AIR. 473 reasonable to ascribe the diurnal period of the temperature found in the dark season to the effect of the wind. A similar period seems to be not uncommon at other arctic stations. The range at such stations is always small, and the maxima and minima may occur at different hours, indicating that other causes than the sun's radiation are regulating the march of the period. Such stations that show the day colder than the night are Bossekop, Lat. 69° 58', December, 1882; Sagastyr, mouth of the river Lena, Lat. 73° 23', December, 1883 ; Polaris Bay, Lat. 81° 36', December, 1871; Polaris House, Lat. 78° 18', December, 1872. The diurnal period resulting from the observations from the Fram will be subjected to a fuller discussion in another chapter, where I shall discuss the radiation, its effect and that of the amount of cloud and of the velocity of the wind, upon the amount of the diurnal range. In order to find the effect of the amount of cloud upon the diurnal period of the temperature of the air, I have made calculations similar to those made for the velocity of the wind (p. 293 to 298). The result is shown in the fol- lowing Tables. Clear. C vercas t. Months. Number of days. Amount of cloud. Mean tempera- ture. Number of days. Amount of cloud.

In the other months — September excluded — we have the ordinary diurnal period. With the sky over- cast, the diurnal period with a minimum in the early morning hours and maxi- mum after noon, is very well developed in all the months except January. The range is greatest in April, both with clear sky and with the sky overcast. In April, May and June, the range is greater with a clear sky than with the sky overcast. The most striking feature seems to me to be (PI. IV. 1 cm. = 1°) the distinct diurnal period of the ordinary march in the winter and dark season, with the sky overcast and relatively higher temperatures. The inverted period with clear sky in the dark season seems to be due to the diurnal period of the wind's direction, as pointed out above (p. 472). The dark-season period, with its stronger, south-easterly winds, is hardly to be accounted for by the radiation from the sun or sky. 478 H. MOHN. METEOEOLOGY. [NORW. POL. EXP. In order to study the relation between the diurnal period of the tempera- ture of the air and the velocity of the wind, I have made computations similar to those worked out above (p. 299 to 303), and give the results in the following Tables.

The difference is greatest (8'°2) in February, and least in December (0'°4). With the weaker winds (PI. 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 (l'°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 O'°17 to O'°12. The greatest range (O'°70) is found in April. 61 482 H. MOHN. METEOROLOGY. [NORW.

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 aperio- dic diurnal range is measured by from 2° to 8°, the periodic range from 0'°2 to l-°7. (PI. III. 1 mm. = 1 ° C.). NO. 17.] TEMPERATURE OF THE AIR. THE ANNUAL PERIOD.

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 O'l 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.

An inquiry into the question as to whether there is a difference between the diurnal period of the amount of cloud with weak winds and that with strong winds, has led to the following results. The days with a wind-velocity less or more than 4'5 metres per second are the same as in the similar tables already given (pp. 299 and 478) for the diurnal period of the velocity of the wind and that of the temperature of the air.

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. PI. VIII.

Cirro-stratus has a less regular period. In winter, summer and autumn, we find a greater amount during the day than during the night ; but in spring the period is reversed. Cirro-cumulus has a maximum of frequency at 2 p. m., and a minimum about 2 a. m. in all seasons. Strato-cumulus has a maximum in the day hours, in spring and sum- mer a couple of hours after noon, in autumn at 10 a. m., and a minimum in the early morning hours, with a rather large range. Cumulus has a very slightly pronounced period with a maximum in the middle of the day, and a minimum at midnight. Stratus shows a maximum in the early morning hours and a minimum at noon or later in the afternoon. The range is rather large in summer and autumn. 522 H. MOHN. METEOROLOGY. [NORW. POL. EXP.

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. The following Tables show the number of cases in which the different forms of clouds have been noted moving from the respective points of the compass (true direction) during the drift of the Fram. The higher forms of clouds are treated separately, the lower clouds comprise cumulo-stratus, NO. 17.] CLOUD. 523 cumulus and stratus. The Tables give the sums of cases of each of the 16 points for the whole year and for the sunny season. In the dark season and in the night, the observation of the form of clouds is very difficult and sometimes impossible. The figures for this season and for the equinoctial months are therefore not to be considered as altogether trustworthy. It is only for the sunny season that they are likely to give results of scientific interest. CIRRUS.

For each month of the drift of the Fram, and for each observation-hour, the sum has been taken of the numbers of cases in which rain, snow, sleet or hail have been noted. 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. For the months from October, 1893, to February, 1894, in which the observations were made only every fourth hour, the numbers for the intermediate hours have been interpolated.

In Winter there are minima at 3 a. m. and at 2 p. m., and maxima at 8 a. m. and at 10 p. m. The range is 0.024. In Spring the minimum occurs at 4 a. m., and the maximum at 2 p. m. The range is 0'092. In Summer the minimum occurs at 6 a. m., and the maximum at 10 p. m. The range is 0.075. In Autumn we have two minima, at 2 a. m., and at 5 p. m., and two maxima, at 9 a. m. and at 10 p. m. The range is 0'028. The early morning hours in all seasons have the least precipitation, and as shown above, p. 513, generally the least amount of cloud. At 10 p. m. winter, summer and autumn have a maximum. Winter and autumn have minima in the afternoon, spring has a maximum at the same time.

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 (lO'l 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 NEGRETTI & ZAMBRA, 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.2 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 (Soderbergs 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 __ 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 : ; -. the bore-holes were deep, one or two in between. The ~_-_ arrangement was as shown in the figure. In cold weather, —__ the reindeer-hair of these muffs might freeze fast to the sides of the holes, but by a little force the rods could 7_~. be torn loose. The observations met with most diffi- H culties during the warm season, when the temperature II. of the. ice was relatively high. The ice was then very ~~ soft and viscous, and in a little while the holes would .~_~. become narrower owing to the slow viscous movement of the ice, and had to be rebored at certain intervals. -- It often happened that the rods then stuck in their -~. holes, and had to be dug out. The rods with the 1TJ thermometers were always left in their holes in order — 1 to give the thermometers the necessary time for accom- ~T, modation. For each observation the rods were hauled As the bore-holes had to be fairly narrow, the thermometers would easilylfreeze fast, or the plastic or viscous ice would often, after a few days, close round the thermometer, especially during the summer. I believe this was in March, 189*, 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.1 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 1 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 plastic 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. SCOTT 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, 1893." Fridtjof Ncmsen. 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 „ February 19. 1'87 „ Snow 4 cm. „ March 10. 2'01 „ „ 4 „ „ April 6. 2-22 „ „ 2'8 „ 10. 2-28 „ 2-8 „ 544 H. MOHN. METEOROLOGY. [NORW. POL. EXP. 1895. May 30. 2'68 metres „ August 30. 3-10 „ The two last figures refer to different floes. The observations of the temperature of the "surface" are not very trust- worthy. 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. Subsequently generally at 8 a. m. The following Tables give the observed temperatures, corrected for the errors of the thermometers. 1894. APRIL. 8 a. m. 8 p. m. Day. Surf. 0-4 m. 0'8 m. 1-2 m. 1-6 m.

In order to obtain the mean temperatures for the depths of 0'4, 0'8, 1*2, 1'6 and 2'0 metres, I have calculated the missing values for each month and year by means of the formula log 4 = log to — f.h, where fo is the temperature at the depth h, t0 at the surface, and f a coeffi- cient (the logarithmic decrement). The formula gives values, whose difference from the observed values ranges from 00-6 for the winter-months to 0°'l 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 vain 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) tm 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 71 562 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 theory1 of the propagation of heat in a soil of constant therrao- metrical heat-conductivity down to great depths retires 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 1 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. I have computed the most probable value of the coefficient of this retardation from the given values by the method of least squares. Depth A.obs.

According to the theory, this number should be equal to the retardation of the phase. Thus the retardation from the ranges = 0'4662 radian = 26'°78 - phase-angles = 0'2557 „ = 14'°65. The theory requires the identity of these two numbers. This requirement is not fulfilled. The phase-angles give a retardation of 14'86 days per metre. The velocity with which the heat-wave is propagated in the ice becomes 24'58 metres in one year, or 6-729 centimetres in one day. The thermometric conductivity K is equal to ~a'-m. Putting T = 1 year = 365'25 X 24 X 60 minutes and r in centimetres, we have from the phase-angles r = 0'002557 -K"=0'91 pr. cm. and min. , - ranges r = 0004662 # = 027 - „ „ HANN gives (L. d. M. p. 741) for ice, JT=0'68. The value derived from the phase-angles is nearest to this value. K =0'68 gives r = 17° instead of our 14'° 65, but it is very near to the otherwise found 16'°3 (p. 564). We have seen that the depth which the heat-wave attains in one year, computed from the phase-angles, is 24'6 metres. To this depth the polar-ice does not reach; its thickness is only about 3 metres. Below the ice is sea- water, the temperature of which is nearly constant throughout the year. At the depth of 3 metres, Professor NANSEN gives the following temperatures1. May June July August Sept.

The minimum probably occurs at the end of the winter, or the beginning of spring. The whole annual variation seems only to be from — l'°5 to — 1'°7, or to have a range of only 0'°2 or even less. 1 Nonv. Polar Exp. Vol. Ill, No. 9. Oceanography of North Polar Basin, p. 314. 566 H.

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

Let Ca = Cb = Cc be the radius^' of the earth (R) and 0 CS a ray from the sun's centre through the centre of the earth, 0 a another ray which would be tangent to the earth in a if there were no refraction in the atmosphere. The ray from the sun's upper limb would be tangent in the point &, 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 ($) so as to touch the earth in a point c, the angle 6 Cc being equal to Q.

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 2 a. m., 8 a. m., 2 p. 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 9th and the 12th Sep- tember and below — 40° on the 1st, 3d and 11th 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 F0hn, 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 3rd and the 12th September, when some rain fell. The windward side of the wind-rose lay thus (see p. 285): Sept. Oct. Nov. Dec. Jan. Feb. Mar. Apr.

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 Flora1 (Lat. 78° 55' N; Long. 48° 40' E), I have put together the following Table.

MOHN. METEOROLOGY. [NORW. POL. EXP. OBSERVATIONS IN EAST-SPITZBERGEN 1894—95 made by Mr. M. EKHOLL. In the summer of 1894 Mr. MARTIN EKROLL made a voyage with his schooner, Wittem 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 ISLAND 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. NO. 17.] OBSERVATIONS IX EAST-SP1TZBERGEN. 655 The frequency of the winds is given as a percentage ol the total number of observations in each month. The force of the wind according to the scale, 0 = calm to 6 = hurricane. "Wittem Barendtz". Lat. 77° 30' N. Long. 20° 55' E. Atm. Pressure Stand. Gr. Sea-Level Mean Temperature of the Air.
