Cumulative wind speed

WebJan 1, 2015 · The cumulative wind speed distribution can be approximated by a 2-parameter Weibull distribution W = 1 - exp [ - (v/v c) m] , where v c is the characteristic speed and m is the Weibull modulus, a shape parameter. We can transform this into a linear correlation. m·ln v - m·ln v c = ln [- ln (1-W)] WebMeasurement of wind was done by use of the cup anemometer based on the use of the cup wheels.
