typhoon

Typhoon, hurricane, and cyclone are all terms for big storms.

Although the word cyclone is often used to refer to a big storm, it is, technically speaking, a large-scale, atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion. Because these generally produce clouds and precipitation, cyclones are often simply referred to as storms. When such storms form around the tropics, they are called tropical cyclones. Tropical cyclones are classified based on their strength. They may start as tropical depressions and progress to tropical storms. The most severe tropical cyclones—those with winds of 74 mph (119 k/mh) or more—are called hurricanes or typhoons. Which term is used depends on where the storm occurs.

Generally, storms that form over the Atlantic Ocean or the Gulf of Mexico are called hurricanes, while those that form over the Pacific Ocean are called typhoons. (The word hurricane is sometimes used for storms that form over the eastern or central North Pacific Ocean.)

Cyclones rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

In casual use, the word cyclone is sometimes used to refer to a tornado (but it is not used this way in scientific contexts).
