I’m glad that you asked! The earth’s rotation creates an energy field that brings the ether to rotate in sync with it, even at a distance. You can see the effects of this in the atmosphere in hurricanes. The ether is very light and so as the energy field spins the ether faster than the earth it creates the same fan effect but for our atmosphere. Hurricanes never cross the equator because that’s where the forces of the earth spinning against the ether and pushing forward against the ether are perpendicular.

tldr: the earth is a really big fan and it makes hurricanes
