Eli5: If heat is energy, how does cold wind exist? How can air move (have cold gusts of wind) if it’s not hot? Where does the energy for movement of cold air come from?

Question

I asked this in school and the teacher thought I was trolling and didn’t answer me. It’s been like 20 years and I still think about it, it drives me crazy lol.

Answer 1

Wind is generally formed by a vacuum sucking air in rather than a force pushing the air. Hot air rises and leaves a vacuum that pulls air toward it, on the global scale this forms wind.

But also there is relativity. The atoms of gases are moving at the same speed as all the gas atoms surrounding them.
