During April through June, the winds were low and easterly through southwesterly. Under 3 percent of the speeds exceeded 10 m/sec; however, on two occasions speeds exceeded 25 m/sec from the south and SSW. The resultant speed was 1.1 m/sec and direction was 184 deg. 66. The winds during July through September were bidirectional, with 26.9 percent blowing from NNE and 41.2 percent from SSW through W. The resul- tant speed was low, 0.4 m/sec, showing the approximate balance between north- erly and southerly winds while the resultant direction was 179 deg, indicating southerly winds occurred slightly more often. For 6.3 percent of the winds during this season, the speed exceeded 10 m/sec--again, primarily from the northeast quadrant. 67. The winds were mixed during October through December, with 33.5 percent blowing from NNE through E, and 6 to 10 percent from each of the westerly directions. The resultant wind speed and direction show the north- easterly dominance at 1.3 m/sec and 14 deg, respectively. Wind speeds 35 exceeded 10 m/sec 14.5 percent of the time, and these winds blew primarily from the northeast quadrant. 68. Present versus past years. There was a tendency for winds to blow more often from the northeasterly directions during 1983 (Figure 7). The dis- tribution is similar to 1982, while during prior years there were more north- westerly winds. The more frequent northeasterly winds occurred during January through March and October through December, while seasonal distributions for April through September are very nearly the same as for prior years. Monthly differences between 1983 and prior years are emphasized in Table 5. 69. Combination of all years. Annual and seasonal distributions of winds for the combined years 1980 through 1983 are presented in Figure 9. Of the 5,250 observations, over 6 percent exceeded 10 m/sec. For those speeds in excess of 10 m/sec, 44 percent occurred during October through December and 32 percent during January through March. Waves 70. This section presents summaries of wave data collected at the FRF. A review of the wave conditions during 1983 and a comparison with previous years is followed by a discussion of the wave climate for 1980 through 1983. Appendix B contains summaries for each gage which include height and period distributions, wave direction distributions, and persistence tables. A dis- cussion of individual major storms is given in Part IV, and Appendix D con- tains hourly wave data for times when the heights Pi. exceeded 2 m at the seaward end of the FRF pier. Present data year, spatial variation 71. The distribution of wave heights for all three gages operated dur- ing the year is shown in Figure 10. For a given frequency of occurrence, wave heights were highest at the gage located 3 km from shore (gage 620), second at the pier end (gage 625), and lowest at the landward end of the pier (gage 615) This pattern of variation (decrease of wave height with depth) is consistent With previous years' data. Refraction, bottom friction, and wave breaking contribute to the observed differences in height. Wave height statistics for the staff gage (gage 615) located at the landward end of the pier in shallow water were considerably different than the other gages.

Consequently, these statistics represent a lower energy wave climate in which the annual mean height is more than 20 percent less than at the seaward end of the pier. 72. The distributions of wave periods for all of the gages are shown in Figure 11. Although the distributions of wave periods for gages 620 and 625 were similar, gage 615 had a higher occurrence of wave periods 6 sec and less primarily due to waves frequently breaking seaward of the gage. This pattern of variation between gages is consistent with data from the previous year. Temporal variation 73. Temporal height and period trends for gages 620 and 625 are shown in Figures 12 and 13, respectively, and are consistent with those for gage 615. Seasonal wave height distribution variations as shown in Figure 14 (gage 625) were similar for all gages; waves were most severe during January through March. Seasonal wave period distributions (Figure 15) (gage 625) were also similar for all gages. In general, the tendency was for the less severe wave conditions during April through September to frequently have wave periods of 38 GAGE 620 VA GAGE 625 ore BS] GAGE 615 Pa ee H959,%ePaParatarataratataretareratetateretetete’ BSAA SAASAASAAAAANASSANSAN) 9.0- 10.0 Satatataratetatetatetete AAAAARARARARARATRELEE aletetetateteretefetetoletarereretetererersrereteretetereteretsreterererers KAASAAAAAAAANAANAASASASSY Raw Shee lee 2.9 IS aratecetelelerererelerelererererererereverere® ASAAAAASAASAS etetevoPoreTerereTeceterererererererere® [XMAS BOER AN Bi ra 2 " ° % ‘JONYNNIIO 4O AONANDAYA 16.9 LONGER 13.9 - 11.0- 12.0- 14.0- 17.0- 11.9 10.9 9.9 Annual wave period distributions for 1983 39 4.9 3.9 Figure 11.

The distribution of wave directions for the year, based on visual observations (Figure 16), revealed that waves approached the north side of the pier 41 percent of the time, the southside 49 percent, and approximately shore-normal 10 percent. However, when wave heights exceeded 2 m at the seaward end of the pier, the waves approached 47 percent of the time from the north, 40 percent from the south, and 13 percent normal to shore. 75. Seasonal variation of wave direction is shown in Figure 17. The northerly tendency during winter and fall and the southerly tendency during spring and summer are consistent with wind distributions discussed previously. Present versus past years 76. Wave height and period distributions for 1983 were similar to the combined 1980 through 1982 distributions. Figure 18 compares the heights and Figure 19 compares the periods for gage 625. There was a tendency for wave periods of 9 sec or longer to occur more often during the year. Seasonal distributions of wave heights showed that a relatively severe January through March was offset by a mild October through December. 77. Wave direction distribution for 1983 was similar to prior years, as can be seen in Figure 16b. Resultant wave height and direction values in Table 6 show that monthly consistency is lower than seasonal and annual. All years combined 78. The 4-year data set between 1980 and 1983 provides the most com- plete description of the wave climate at the FRF. Figure 20 indicates that for the lower 97 percent of the wave heights for gages 620 and 625, the dis- tributions are approximately the same. However, for wave heights greater than approximately 2.5 m, the Waverider shows a greater proportion of higher waves. Figure 21 indicates that spatial differences in wave period were small, except that there was a higher percentage of 5- to 6-sec waves at the nearshore Baylor than at both other sites. 79. The joint distributions of wave height versus period for gages 620 and 625 are shown in Tables 7 and 8. The distributions are based on over 4,670 observations, and the values presented can be converted to percent by di- viding by 10. Higher waves are generally associated with longer wave periods. 80. Seasonal distributions of wave height and period for gage 625 are shown in Figures 22 and 23, respectively.

Annual and seasonal wave direction distributions for the combined years are shown in Figure 24. Fifty-two percent of the waves approach from the south, 43 percent from the north, and 5 percent approximately shore- normal. When wave heights exceed 2 m, 57 percent approach from the north, 34 percent from the south, and 9 percent shore-normal. Longshore Currents 82. In this section, the results of daily surface longshore current measurements are presented. Figure 25 shows the 1983 measurements at the beach, pier midsurf, and pier end locations. Since the relative influences of the winds and waves vary with position from shore, the current speeds and, to some extent, direction vary at the three current measurement locations. Mag- nitudes generally are the largest at the midsurf location and smallest at the end of the pier. However, annual mean currents (Table 9) were directed south- ward at 6 cm/sec at the beach location, only 2 cm/sec at the midsurf location, and 13 cm/sec at the seaward end of the pier. Despite frequent reversals, the mean monthly currents were directed southward during fall and winter and northward during spring and summer. This seasonality of currents was consis- tent with wind and wave patterns previously discussed. 49 JAN-MAR 80-83 APR-JUN 80-83 JULSsz2lP tits OCT-DEC 80-83 HO Calo) zéql0)= % CZ) aH Nnponmn onmowo ao Le enn n enna aravavavavatavavavatatavaratavats COo00 170:070707070767070107070707070707070,070 10781078 ooo oO ODM LMM MMM IM A ezo0o TKWSSWWSANSANINAAA = 3 a 4 [07070-0:07070_0_0-0"070_0"0"0_00_010_01010"0_01610_6,0"80_6"0 0": > Ie 4 1 LILI FAT A LL LPL [92050:050101010:0:01016:0:0:0,0:0,9:6,0:0,9;0.0.0.8 CHILL ILL L ML LA WSS 2950200,0:0,0:0.0:0,0:0,0-0:0:0.0.0.0,0;9,9.0,9,9.9-.

Longshore surface currents for 1983 were reasonably consistent with previous years of data (Figures 26-28). However, at the midsurf location, the monthly means were directed to the south in response to storm waves during April and September. All years combined 84. All locations show consistent temporal variations and distinct spatial differences in both magnitude and direction (Figure 29). Near-zero annual means (Table 9) for both locations within the surf zone reflect the seasonal variations and frequent reversals caused by the varying wind and wave conditions at the FRF. These contrast with the predominantly southward cur- rents at the pier end. Tides and Water Levels 85. Water level variations caused by astronomical and meteorological forces are discussed in this section. Results for 1983 are followed by a comparison with previous data. All tidal heights are referenced to the local 1929 NGVD unless otherwise stated. 53 CURRENT SPEED, CH/SEC JIN FEB WAR APR MAY JUN JL AUG «SEP «(OCT )«€6NOV) «GEC ANNUAL MONTH Figure 26.

Tides at the FRF are semidiurnal with both daily high and low tides approximately equal. Mean range varied from 95 cm in late spring to 102 cm in January. Mean sea level was 19 cm above NGVD. The highest water level for the year was measured on 28 January during the time of a severe storm with waves in excess of 3.6 m at the seaward end of the pier (Part IV). This extreme is within a few centimetres of the highest water level measured since 1978. Water levels in excess of 130 em occurred on 25 March and 25 October during storms. 1983 versus past years 87. Since late 1981 there has been a rising trend for the water levels at the FRF (Table 10 and Figure 30). Mean sea level and other mean level statistics are approximately 10 cm above prior years. This same trend has been verified at nearby locations such as Hampton Roads, Va. In Figure 31, the distribution of daily high, daily low, and hourly tidal heights for 1983 and prior years are presented for comparison.

The results of daily measurements of surface water temperature, visibility, and density are presented in this section. The summaries rep- resent single observations made near 0700 EST and therefore may not reflect daily average conditions since such characteristics can change rapidly within a 24-hr period. A discussion of 1983 data is followed by a comparison with previous years. Water temperature 90. Present year. Daily sea-surface water temperatures at the seaward 59 end of the FRF pier (Figure 33) experienced large variations during June through September when frequent offshore winds blew warm surface water sea- ward, allowing upward and landward circulation of much colder and more turbid bottom water. Persisent offshore winds (as high as 10 m/sec) during the first 12 days of August were responsible for unseasonably cold water temperatures during the month. Onshore winds reversed this circulation, piling up warm surface water against the shoreline. Monthly mean temperatures (Table 11) were lowest during January through March and highest from July through September. 91. 1983 versus prior years. In general, water temperatures during the year were higher than for prior years (Figure 34). 92. Combined years. The distribution of surface water temperatures for all years combined is shown in Figure 35. Temperatures in excess of 25° C can be expected 4 percent of the time (or 14 days per year), while tempera- tures below 4° C can be expected less than 6 percent of the time (or 20 days per year).

Distribution of surface water temperatures for 1980 through 1983 salts, soluble organic material, detritus, living organisms, and inorganic particles in the water. These dissolved and suspended materials change the absorption and attentuation characteristics of the water, which vary daily and throughout the year. 94. The surface water visibility at the seaward end of the pier varies in a manner similar to that of the temperature, with lows in January through March and highs in June and July (Figure 36). Since the pattern of offshore and onshore winds that produces major temperature differences also controls the visibility, the warm surface water is usually clearer, while the cooler bottom water contains large concentrations of suspended matter. 95. Present data year. Daily water visibility values, measured at the seaward end of the pier using a secci disc, reflect the wind-dominated pro- cesses discussed above. Between May and August the visibility was occasion- ally above 6 m, however, visibility was less than 2 m almost as often during those months. Table 11 shows the monthly means for the year. 96. 1983 versus prior years. Visibility during 1983 was similar to prior years (Figure 37), although visibility was lower during January through March and higher during May through July. 62 VISIBILITY, VISIBILITY, J 60FEB OMAR CCORPR AY CNN OCLCOUC( JH : B35-B37. Data for 1980 through 1983 are in Figures B12-B14, B28-B30, and B41-B43. Peak spectral wave period distribution. Annual, seasonal, and monthly peak wave period T, distributions histograms for 1983 are presented in Figures B6-B8, B25, B26, B38, and B39; data for 1980 through 1983 are in Figures B15-B17, B31-B32, B44, and B45. Persistence of wave heights. Tables B6, B16, and B26 show the number of times throughout 1983 when the specified wave height was equaled or exceeded at least once during each day for the duration (consecutive days) indicated; data for 1980 through 1983 are in Tables B11, B21, and B31. For example, Table B6 for gage 625 (pier end Baylor) indicates wave heights equaled or ex- ceeded 1.0 m, 41 times for at least 1 day; 34 times for at least 2 days; 25 times for at least 3 days; 18 times for at least 4 days, etc. Therefore, on seven occasions it was expected for the height to have equaled or exceeded 1.0 m for 1 day exactly; on nine occasions for 2 days; on seven occasions 3 days; etc. Note that the height exceeded 1.0 m, 41 times for 1 day or longer, while heights exceeded 0.5 m only 26 times for this same duration. This occurred because the longer durations of lower waves may be interspersed with shorter, but more frequent, intervals of higher waves. For example, the one time that wave heights exceeded 0.5 m for 64 days may represent 5 or 10 different times the height exceeded 1 m for shorter duration. Wave roses. For the pier-end Baylor gage (625), wave roses showing the distribution of wave height versus approach angle are presented. Data for 1983 are in Figures B9 and B10, while 1980 through 1983 data are in Figures B18 and B19. The angles are referenced to true north. Northerly wave angles (e.g., less than 70 deg) generally produce southward currents while south- erly wave angles greater than 70 deg produce northward currents. Spectra. Spectra for the pier-end Baylor gage (625) for days when wave heights exceeded 2 m are presented in the last fig- ure. The plots show energy density as a function of wave frequency.

Whenever the wave height Ha exceeded 2.0 m at the seaward end Co) of the Field Research Facility (FRF) pier, data were collected hourly. The available data for the 24 storms (reported in Part VI of the main text) are presented in Figures D1-D24. Atmospheric Pressure 2. Reported in millibars, these data are useful for documenting the type of storm, the passage of fronts, and the intensity of the atmospheric pressure system. Wind Speed 3. Local winds are generally responsible for the wave conditions at the FRF. Wind speed is reported in metres per second. Wind Direction 4, Referenced to true (star) north, the wind direction indicates the direction from which the winds are blowing, e.g., winds blowing from west to east are referred to as having an angle of 270 deg. Wave Direction 5. Referenced to true (star) north, the wave direction measurements are taken at the seaward end of the FRF pier. The pier axis (considered perpen- dicular to the beach at the FRF) is oriented 70 deg east of true north; con- sequently, wave angles greater than 70 deg imply the waves were coming from the south side of the pier. D1 Gage 625 H, ) 6. The wave height, measured in metres, was that obtained from the Baylor wave staff located at the seaward end of the FRF pier. Wave Period 7.
