10 year average wind speed (F) and Weibull scale (a) and shape parameter (k) for height 120m
The Weibull scale parameter a is a “measure” for the average wind speed. As to be expected, the average wind speed is higher in winter and autumn than in summer and spring.
The Weibull shape parameter k is a “measure” for the shape of the wind speed distribution: the higher k, the smaller the spread in wind speeds.
10 year average wind speed F uses a color scale for 0-200m ranges from 2-11 m/s and for heights above 200m from 5-12 m/s.
