The Coriolis effect is what causes hurricanes in the Northern Hemisphere to rotate counterclockwise. The Coriolis effect is a result of the Earth's rotation causing moving objects, such as air masses in a hurricane, to curve to the right in the Northern Hemisphere. This leads to the counterclockwise rotation of hurricanes in this region.
