# How are wind speeds typically distributed?

What probability distribution do wind speed measurements typically follow?

I have seen a Weibull distribution used, but the page was a bit lacking on background information so I would appreciate confirmation and a reference, if possible.

If it is a Weibull, are there typical parameters that are used, or can these vary?

Thanks.

As a starting point for estimation, it's usual to take $k=2$; this is equivalent to the Rayleigh distribution. However, the Weibull is more generalised, and often provides a better fit (i.e. $k$ isn't exactly 2).
