 
 <translate> "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round their central clear eye, with their winds blowing counterclockwise in the Northern Hemisphere and blowing clockwise in the Southern Hemisphere. The opposite direction of circulation is due to the Coriolis effect. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. This energy source differs from that of mid-latitude cyclonic storms, such as nor'easters and European windstorms, which are fueled primarily by horizontal temperature contrasts. Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter.

Where does a tropical cyclone or hurricane get its energy?
The answer is the evaporation of water from the ocean surface , which ultimately recondenses into clouds and rain when moist air rises and cools to saturation <ibo> "Ebe okpomọkụ" na-ezo aka n'ebe usoro ndị a sitere, bụ́ ndị na-etolite n'ihe fọrọ nke nta ka ọ bụrụ nanị n'oké osimiri ndị dị n'ebe okpomọkụ.
