What gives hurricanes their rotation?

Hurricanes gain their rotation primarily due to the Coriolis effect, which is the result of the Earth's rotation. As warm, moist air rises from the ocean surface, it creates a low-pressure area that draws in surrounding air. The Coriolis effect causes this incoming air to twist, resulting in the characteristic counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Additionally, the conservation of angular momentum helps to strengthen the storm's rotation as it intensifies.
