For Cyclone we have terms and definitions in 12 topics. The topics are Air Quality, Boating, Climatology, Hurricane, Meteorological, Nature, Nautical, Oceanography, Physical Geography, Science, Surf and Weather.

Cyclone (Air Quality)

An air pollution abatement device that removes heavy particles from an air stream through centrifugal force

Cyclone (Boating)

1) A hurricane or other very intense storm, usually in tropical regions. 2) A low-pressure system. An anticyclone is a high-pressure system. 3) Cyclonic winds rotate counter-clockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere.

Cyclone (Climatology)

An atmospheric circulation that rotates counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere, that usually has a diameter of 2000 to 3000 kilometers

Cyclone (Hurricane)

An atmospheric m. circulation (low-pressure system) with rotating and converging winds, in which the center has a relative pressure minimum. It usually has a diameter of 2000 to 3000 kilometers. When developing, a cyclone typically consists of a warm front pushing northward and a cold front pushing southward with the center of low pressure (cyclone center) located at the junction of the two fronts. Cyclones in the Northern Hemisphere rotate counter-clockwise while Southern Hemisphere cyclones rotate clockwise.

Cyclone (Meteorological)

An atmospheric closed circulation rotating counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Cyclone (Nature)

The name given to a hurricane when it forms over the Bay of Bengal or the northern Indian Ocean

Cyclone (Nautical)

The generic term for a tropical weather system, including tropical depressions, tropical storms and hurricanes.

Cyclone (Oceanography)

An atmospheric low pressure system in which winds spiral in towards a region of low pressure - anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Cyclones are characterised by cloudiness and high humidity.

Cyclone (Physical Geography)

Area of low pressure in the atmosphere that displays circular inward movement of air. In the Northern Hemisphere circulation is counterclockwise, while Southern Hemisphere cyclones have clockwise wind patterns.

Cyclone (Science)

A circulating air mass that rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Also used in many parts of the eastern hemisphere as synonymous to "hurricane".

Cyclone (Surf)

An atmospheric closed circulation rotating counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Can be a high-pressure or low-pressure cyclone.

Cyclone (Weather)

An area of closed pressure circulation with rotating and converging winds, the center of which is a relative pressure minimum. The circulation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Also called a low pressure system and the term used for a tropical cyclone in the Indian Ocean. Other phenomena with cyclonic flow may be referred to by this term, such as dust devils, tornadoes, and tropical and extratropical systems. The opposite of an anticyclone or a high pressure system.
