WebThere are several functional and mechanical reasons for using the Weibull distribution in modeling wind speeds. In a study of wind speed durations above and below xed speeds, Corotis(1979) determined that the Rayleigh distribution is reasonable in modeling wind speeds. In his previous research the following cumulative distribution function had ... WebThe probability density function for the Rayleigh distribution is. P ( x; s c a l e) = x s c a l e 2 e − x 2 2 ⋅ s c a l e 2. The Rayleigh distribution would arise, for example, if the East and North components of the wind velocity had identical zero-mean Gaussian distributions. Then the wind speed would have a Rayleigh distribution. chrome suchmaschine
