Why does wind blow in gusts?
In: Earth Science
The Earth is (roughly) a sphere. As a sphere, you cannot make straight lines perfectly cover the whole thing. This is a part of [the Hairy Ball theorem.](https://en.wikipedia.org/wiki/Hairy_ball_theorem)
Wind, which is moving (roughly) in a straight line, cannot keep moving that way for long. Yeah, there is differences of pressure and ground obstructions and yada yada, but it really boils down to (slightly advanced) geometry.
Cool thing is, ring-style space stations CAN have perfectly smooth flowing wind.
