Can someone explain how wind can spiral in to a point? Where does the air "go"? Or does this create a higher pressure?

If it’s showing surface winds, it goes up. On windy.com there’s an altitude slider that lets you choose which wind level you’re looking at. Haven’t found that yet here.

Oh thanks that altitude slider is very interesting. Makes me want to see a 3d visualization.
