When a hurricane approaches the coast directly it is likely to cause a larger storm surge (left) than a hurricane that approaches at an oblique angle (right). For example, Cyclone Yasi made a direct hit on the Queensland, Australia coast in 2011, causing seven meters (23 feet) of storm surge.
The ultimate energy source for hurricanes is the warmth of tropical oceans. The warm waters evaporate, and the water vapor is the fuel that powers hurricane heat engines
TStorms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise. This difference is because of Earth's rotation on its axis.
The center of low pressure in the storm is the eye. The lower the central pressure, the fiercer the storm, and the higher the winds .
