The coriolis effects drives air circulation
When a pocket of air heats up, it causes that hot air to rise. Other air rushes into the space to replace the risen hot air.
This phenomenon is “wind”. If Earth didn’t rotate, warm air at the equator would simply transfer to the poles.
But because the Earth rotates, air starts swirling like a merry-go-round.
This is why storms veer counter-clockwise in the northern hemisphere and clockwise in the southern hemisphere.
