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.
