cyclone

(Learning Modules / Geography / Weather forecasting) A circulating storm around a low pressure centre. The term cyclone is usually restricted to tropical storm systems (temperate ones are called 'depressions'). A cyclone with wind speeds in excess of 120 kph is a hurricane in the Atlantic, a typhoon in the western Pacific or a tropical cyclone in the Indian Ocean. The winds circulate anticlockwise in the northern hemisphere....

cyclone

1.a low-pressure area, around which wind flow is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The term is sometimes used to describe storms occurring in the atmosphere; in the Indian Ocean it is used to designate a tropical cyclone. 2. a device for the separation of various particles from a drilling fluid, most commonly used as a desander. The fluid is pumped tangentially into a cone, and the fluid rotation provides enough centrifugal force to separate particles by mass weight. ...

Cyclone

Air cleaning device which uses a combination of centrifugal and gravitational forces to separate particles out of an air stream. Contaminated air is introduced tangentially so that solids are thrown outwards against the walls of the cyclone and fall to the bottom under gravity. Irrigated and multi versions exist.

Cyclone

A tropical revolving storm with winds of hurricane force, circulating anti-clockwise in the northern Hemisphere and clockwise in the Southern hemisphere. In temperate latitudes a cyclone is properly a Depression. In the West Indies a cyclone is called a hurricane. In the China Seas it is known as a typhoon. In Australia it is called a 'Willy-Willy'...

Cyclone

The Cyclone was a French Simoun Class destroyer (torpilleurs) of 1319 tons displacement launched in 1925. The Cyclone had a top speed of 33 knots and a range of 4800 km at 15 knots and carried a complement of 138. She was armed with four 5.1 inch guns; two 37 mm anti-aircraft guns and six 21.7 inch torpedo tubes arranged in two triples.
