I live in a windy place. Right now, I am looking at clouds moving really fast. But cloud are just water vapor no? So how can they keep their shape and move as a whole piece instead of just being blown away by the wind?
Edit : thank you for all those detailed explanation ! I guess I’ll spend way more time looking at clouds now !!

Just one quick thing to add: Clouds are really really big. It’s hard to gauge how big they are because they tend to be rather far away.
They look substantial because you’re looking through a lot of water droplets. The light needs to pass through enough volume of cloud to be scattered.
But they don’t have a sharp edge, so the parts that look like “cloud” are very large and so despite the fact that there’s all that wind, the small scale changes aren’t very noticeable because there needs to be a significant change of a large volume to change the scattering of light.
