Reply to comment by chemist612 in Eli5: How come it doesn’t rain all year round? by TheRunningMD

But wouldn’t that mean that the water droplets would have to travel thousands of miles “close to the surface” because usually those places are far away, and not just go up like 2K up?

Up cold is a lot closer than low cold.

Yes, but the jet stream is powerful and mixes the air pretty fast. Summer storms have a lot of energy, which is why they tend to be so destructive

Sweet. Is there a physical reason why wind moves to colder places?

Wind is just hot air and cold air moving past each other. Areas of high pressure are where it is hotest and areas of low pressure are colder, so evaporation happens somewhere warm and high pressure then moves via wind (advection) to somewhere colder with low pressure.
