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.
