A tropical cyclone is a rapidly-rotating storm system characterized by a
low-pressure center, strong winds, and a spiral arrangement of thunderstorms
that produce heavy rain. Depending on its location and strength, a tropical
cyclone is referred to by names such as hurricane , typhoon tropical storm,
cyclonic storm, tropical depression, and simply cyclone.
Tropical cyclones typically form over large bodies of relatively warm water.
They derive their energy from 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. The strong rotating
winds of a tropical cyclone are a result of the (partial) conservation of
angular momentum imparted by the Earth's rotation as air flows inwards
toward the axis of rotation. As a result, they rarely form within 5° of
the equator. Tropical cyclones are typically between 100 and 4,000 km
(62 and 2,485 mi) in diameter. A cyclone is turned into a hurricane when
the wind speed reaches 120 kilometres per hour (75 mph).
The term "tropical" refers to the geographical origin of these systems, which
form almost exclusively over tropical seas. The term "cyclone" refers to their
cyclonic nature, with wind blowing counterclockwise in the Northern Hemisphere
and clockwise in the Southern Hemisphere. The opposite direction of circulation
is due to the Coriolis force.
