Surface currents in the Northern Hemisphere rotate in a direction. In the Southern Hemisphere, the surface currents rotate in a direction.

Explanation:

Surface currents in the Northern Hemisphere rotate in a Clockwise direction whereas in  the Southern Hemisphere, the surface currents rotate in a anticlockwise direction. This happens because of the Coriolis effect, because of this Coriolis effect surface currents are shifted to angle of 45°. Therefore, it deflects the current towards right in northern hemisphere and towards left in southern hemisphere.

The northern hemisphere goes clockwise thats all i know
