type of storm characterized by high winds rotating around a low pressure area
Cyclone Definition from Language, Idioms & Slang Dictionaries & Glossaries
Webster's Revised Unabridged Dictionary (1913)
A violent storm, often of vast extent, characterized by high winds rotating about a calm center of low atmospheric pressure. This center moves onward, often with a velocity of twenty or thirty miles an hour.

\cy"clone\, n.
1. (meteor.) in general, a condition of the atmosphere characterized by a central area of pressure much lower than that of surrounding areas, and a system of winds blowing inward and around (clockwise in the southern hemisphere and counter-clockwise in the northern); -- called also a low-area storm. it is attended by high temperature, moist air, abundant precipitation, and clouded sky. the term includes the hurricane, typhoon, and tropical storms; it should not be applied to the moderate disturbances attending ordinary areas of low pressure nor to tornadoes, waterspouts, or "twisters," in which the vertical motion is more important than the horizontal.
2. a tornado. see above, and tornado. [middle u. s.] [
\cy"clone\ (s?"kl?n), n. [gr.&?;&?;&?;&?;&?; moving in a circle, p. pr. of &?;&?;&?;&?;&?;, fr. ky`klos circle.] (meteor.) a violent storm, often of vast extent, characterized by high winds rotating about a calm center of low atmospheric pressure. this center moves onward, often with a velocity of twenty or thirty miles an hour.
note: the atmospheric disturbance usually accompanying a cyclone, marked by an onward moving area of high pressure, is called an anticyclone.

Cyclone Definition from Science & Technology Dictionaries & Glossaries
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.

The CYCLONE, was a vacuum tube computer, built by Iowa State College (later University) at Ames, Iowa. The machine was placed into operation in July 1959. It was based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann. The prototype of this machine is ILLIAC, the University of Illinois Digital Computer. The IAS specification stated, 40 bit words, 2 20 bit instructions per word, each instruct had an 8 bit op-code and a 12 bit operand or address field. In general IAS based computers were not code compatible with each other, although originally math routines which ran on the ILLIAC would also run on the Cyclone.

In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. According to the NHC glossary, warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune. Cyclogenesis describes the process of cyclone formation and intensification. Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.

Environmental Engineering (English ver.)
(Meteorology) 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. Also see Typhoon and Coriolis Effect.
