Why do typhoons in the northern and southern hemispheres rotate in different directions? Can you specifically talk about the relationship between their direction and the earth's rotation deviation?

First of all, you should understand that typhoons are cyclones.

Followed by cyclones, the ground is low pressure, high altitude is high pressure.

Then you will understand that the wind is influenced by geostrophic deflection, with the northern hemisphere to the right and the southern hemisphere to the left.

So the direction is different.

This picture is from the northern hemisphere because it leans to the right.
