Where does the wind go?

[Farlo]

Hi all, yesterday I was watching (thankfully from my bike) a few colleagues pumping in all directions and catching a gust occasionally for a ~100 meters run. You could see the gusts appear and disappear from the water surface and I started thinking: by the way, where does the wind go? If you look at it like a pressure wave, why does it stop? You know that feeling when you see people planing ahead but by the time the gust should hit you it's gone completely. Or sometime it will form from nowhere, blast for a couple of seconds in the middle of the spot, and then vanish. I suspect it is a complex 3D problem with lots of maths but has any of you heard about a meaningful model?
