Which way do hurricanes/tropical cyclones spin?

North of the Earth's equator, hurricanes spin counterclockwise, when looking down from above the hurricane. South of the equator, hurricanes spin clockwise. The reason for this difference is the earth's rotation, which gives rise to what is known as the Coriolis acceleration, balanced by the low pressure at the center of the hurricane, typhoon, or cyclone. In fact, this spin direction of hurricanes is known as "cyclonic". The opposite spin direction is known as "anti-cyclonic". Cyclonic-spinning weather patterns have low pressure at the center, while anti-cyclonic weather patterns have high pressure at the center.
