Results 



Annual and monthly joint probability distributions of wind speed 

 versus direction were computed. Wind speeds were resolved into 3-m/sec 

 intervals, whereas the directions were at 22.5-deg intervals (i.e., 16-point 

 compass direction specifications). These distributions are presented as wind 

 "roses, " such that the length of the petal represents the frequency of occurrence 

 of wind blowing from the specified direction, and the width of the petal is 

 indicative of the speed. Resultant directions and speeds were also determined 

 by vector-averaging the data (see Table 2). Wind statistics are presented in 

 Figures 6-8.
