13. A percent of the time, including three occasions when the wind speed ex- 

 ceeded 15 m/sec. More than three out of every four times, when the speed ex- 

 ceeded 10 m/sec, the winds blew from north through east-northeast. 



35. Strong seasonal tendencies measured during the year are shown in 

 Figure 7. During January through March the winds had a bimodal distribution 

 approximately equally split between the northeastern quadrant and the 

 southwestern quadrants. Wind speeds exceeded 10 m/sec 16.8 percent of the 

 time during the season. Winds were from southerly directions in the Spring 

 with less than 8 percent exceeding 10 m/sec. Though predominantly from the 

 northeastern quadrant during the summer, relatively low speeds were measured 

 31 percent of the time from the southwestern quadrant. During October through 

 December winds exceeded 10 m/sec 19.5 percent of the time and were predomi- 

 nantly from northerly directions. 



36. Present versus past years. In comparison to prior years there were 

 fewer occurrences of winds from the southwestern quadrant and more from the 

 northeastern quadrant, particularly from July through December. General 

 differences in the distribution of wind directions can be seen in Table 4. 

 Depending on the quadrant the resultant direction is in, the tendency for more 

 northerly or southerly and easterly or westerly direction can be seen. For 

 example, the annual distribution for 1985 has a resultant direction of 11 deg 

 while the 1980 through 1984 resultant is 350, indicating both had a northerly 

 tendency. On the other hand, during 1985 winds blew more frequently from 

 easterly directions in comparison to prior years when there was a westerly 

 predominance. 



37. All years. Winds at the FRF tend to blow most often from the 

 northeasterly and southwesterly quadrants (Figure 8) . Predominant wind direc- 

 tion varies with season; however, winds in excess of 10 m/sec tend to blow 

 most often from north through east-northeast. The most significant effect the 

 addition of the 1985 data had on the annual distribution of winds was a 

 slightly higher frequency of winds from the northeast and a corresponding 

 lower frequency from south-southwest.
