cyclone(redirected from Cyclones)
Also found in: Thesaurus, Medical, Encyclopedia.
a. An atmospheric system characterized by the rapid inward circulation of air masses about a low-pressure center, usually accompanied by stormy, often destructive weather. Cyclones circulate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
b. A violent tropical storm, especially one originating in the southwestern Pacific Ocean or Indian Ocean.
2. A violent rotating windstorm, especially a tornado.
3. Any of various devices using centrifugal force to separate materials.
[From Greek kuklōn, present participle of kukloun, to rotate, from kuklos, circle; see kwel- in Indo-European roots.]
cy·clon′ic (-klŏn′ĭk), cy·clon′i·cal adj.
1. (Physical Geography) another name for depression6
2. (Physical Geography) a violent tropical storm; hurricane
[C19: from Greek kuklōn a turning around, from kukloun to revolve, from kuklos wheel]
cyclonic, cyˈclonical, ˈcyclonal adj
(Agriculture) trademark Austral and NZ (of fencing) made of interlaced wire and metal
1. a large-scale atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion, counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere.
2. (not in technical use) a tornado.
3. a device for removing small or powdered solids from air, water, or other gases or liquids by centrifugal force.
cy•clon′ic (-ˈklɒn ɪk) adj.
1. A system of winds that spiral in toward a region of low atmospheric pressure, circling counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Compare anticyclone.
2. A violent rotating windstorm, such as a hurricane or tornado.
Did You Know? Technically, a cyclone is nothing more than a region of low pressure around which air flows. In the Northern Hemisphere, the air moves counterclockwise around the low-pressure center, while in the Southern Hemisphere, the air travels clockwise. Meteorologists also refer to tropical cyclones, which develop over warm water and can be huge, severe storms. Strong tropical cyclones are better known as hurricanes or typhoons, depending on where in the world they occur. Hurricanes occur in the Atlantic Ocean and Gulf of Mexico, while typhoons occur in the Pacific Ocean. Such storms can be extremely devastating: two cyclones hit a coastal section of India within a few days of each other in 1999, killing an estimated 10,000 people. Because the word cyclone broadly defines a kind of air flow, cyclones are not confined to our planet. In 1999, the Hubble Space Telescope photographed a huge cyclone on Mars.
an atmospheric disturbance characterized by powerful winds spinning in the shape of a vertical cylinder or horizontal disk, accompanied by low pressure at the center. — cyclonic, adj.See also: Wind
A low-pressure tropical storm with high speed rotating winds.
