Thanks for the heads up on a "Rayleigh distribution" (from http://en.wikipedia.org/wiki/Rayleigh_distribution):

"One example where the Rayleigh distribution naturally arises is when wind speed is analyzed into its orthogonal 2-dimensional vector components. Assuming that the magnitude of each component is uncorrelated and normally distributed with equal variance, then the overall wind speed (vector magnitude) will be characterized by a Rayleigh distribution."

That is cool, I wonder if I will ever use it.
