PART V: DATA AVAILABILITY AND RESULTS 



62. This part provides results of the weather, wave, surface current, 

 tidal, water characteristic, survey, sediment, and photographic measurements 

 made during the year. Table 1 is intended as a quick reference guide to show 

 the dates for which various types of data are available. Wave gage histories 

 which may explain major gaps in the data are provided in Appendix B. Although 

 this report is intended to provide basic data for analysis by users, many of 

 the daily observations have been summarized by month, season, and year to aid 

 in interpretation. If individual data are needed, the user can obtain the 

 detailed information by following the procedures described in paragraphs 6 

 and 7 . 



Meteorological Data 



63. Table 2 summarizes monthly averages of the following daily measure- 

 ments: cloud cover, visibility, dew point, and atmospheric pressure. Results 

 of air temperature, precipitation, and wind speed and direction measurements 

 for 1981, as well as prior years, are presented below. Appendix D contains 

 hourly atmospheric pressure, wind speed, and wind direction data collected 

 during storm conditions for 1981. 



Air temperature 



6A. Air temperature measurements are summarized herein using the daily 

 highest and lowest temperatures measured by maximum and minimum thermometers. 

 Daily average temperatures are unobtainable since only one observation per day 

 was made. The warmest months at the FRF in 1981 were June through September; 

 the coolest months were typically January and February (see Table 2 and Fig- 

 ure 5. Monthly average daily high and low temperatures for 1981 were very 

 similar to those for 1980. Annual average daily high temperature was 20° C, 

 less than 1° C higher than for 1980. Annual average daily low temperature 

 for both years was 11° C. As it was for 1980, the monthly range of tempera- 

 tures for 1981 was the smallest during the warm summer months and as large 

 as 31° C in February and December. These tendencies reflect the complex in- 

 teraction of (a) ocean, whose temperature varies slowly, (b) winds, whose di- 

 rection and speed can change very quickly, and (c) large airmasses, which can
