White noise static is random but also follows a pattern so that any chunk of white noise will look pretty much identical to any other chunk of white noise. If they are replicating a wind noise it would be pretty much the same as white noise, totally random but following a strick pattern.

See also how any normally distributed random event will create a bell curve of probability. The pattern is so strick it is a corner stone of statistics, however it's cause it's pure randomness.
