Winds 













62. Since local winds frequently control nearshore currents and wave 

 conditions, an understanding of the wind and wave climate at any coastal loca- 

 tion is important to most studies of hydrodynamic and sedimentary processes. 

 In this section, wind characteristics at the FRF are discussed based on mea- 

 surements made four times per day. 



63. Present year . The distribution of winds during 1983 is shown in 

 Figure 7. Winds blew from NNE through ENE directions 25.7 percent of the 

 time, from SSW through WSW 25.6 percent, and 4 to 7 percent for each of all 

 the other directions during the year. The resultant wind speed and direction 

 was 0.6 m/sec from 28 deg east of true north (Table 5). When speeds exceeded 

 10 m/sec 82 percent of the time, the winds were from N through ESE. 



64. Wind distributions changed with the season such that during January 

 through March, 63.4 percent blew from northerly directions. The resultant 

 magnitude and direction were 2.8 m/sec and 21 deg, respectively. For the 



12 percent of the observations when the wind speed exceeded 10 m/sec, the wind 

 was directed from N through ENE (Figure 8).
