Hot air rises, the sun heats up the air, but we only get sun on one side at a time as we rotate. This causes a differential and air rushes in to fill it.
Just think of it like the earth is inside a glass ball. Heat from the sun causes the air to expand. It can’t expand outside the glass ball. So it expands out, across the earth. At the same time, different parts of the earth are cooling. Causing the air to contract. I think that is what causes jet-streams but I’m not 100% sure
And don’t want to mis-inform.
Yeah, it’s pretty crazy. Seems like it should be constant chaos.

In a way it is. But keep in mind that at large scales, things appear to move in slow motion. Because the speed of diffusion doesn't care about how large a region is. Only the difference in pressure/temperature at the boundaries.

Uneven heating of the earth, causing expansion and contraction of the air = wind
