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.
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.
A tornado. See above, and Tornado.
a type of separator for removal of larger particles from an exhaust gas stream. Gas laden with particulates enters the cyclone and is directed to flow in a spiral causing the entrained particulates to fall out and collect at the bottom. The gas exits near the top of the cyclone. ( 099)
a violent, rotating windstorm
equipment in which the particles in a flue gas are given a circular motion to spiral down the walls of the cyclone while the cleaned flue gas moves upward through the centre

A weather system with a counterclockwise circulation in the northern hemisphere and clockwise circulation in the southern hemisphere. Cyclones are normally associated with low atmospheric pressure and are thus called Low Pressure Systems.
Large-scale closed circulation system in the atmosphere above the Indian Ocean and South Pacific with low barometric pressure and strong winds that rotate clockwise. Maximum wind speed of 64 knots or more [See « hurricane » for the western Atlantic and eastern Pacific and « typhoon » for the western Pacific]. (in EM-DAT, « cyclone » is a disaster subset of disaster type « wind storm »).
A type of atmospheric disturbance characterized by masses of air rapidly circulating, clockwise in the southern hemisphere and counterclockwise in the northern hemisphere, about a low-pressure center. While even the weakest of low-pressure storms can be defined as a cyclone, the term is most often associated with stormy, often destructive, 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.
A low pressure cell, or a large storm system with counterclockwise air circulation.
An area of low pressure around which winds blow counterclockwise in the Northern Hemisphere. Also the term used for a hurricane in the Indian Ocean and in the Western Pacific Ocean.
An area of low atmospheric pressure that has a closed circulation. Cyclones (or more commonly called 'low pressures') usually bring about marked changes in the weather.

Depressions of the temperate zones were formerly often referred to as cyclones, but depression or low is now used to distinguish them from the tropical storms. The term "cyclonic depression" is still sometimes used for a depression, as also is "extra- tropical cyclone". Back to the top

rotatory system of winds which converge towards a point where the atmospheric pressure is minimum. Dark matter a hypothetical form of matter, according to the cosmological theories, that does not emit light and therefore escapes observations. Scientists think that the dark matter is diffused in the whole Universe, mixed to the ordinary matter, and is constituted of particles such as, for example, neutrini. The dark matter is almost definitely present in the halos that surround the galaxies and in the space among the galaxies of a cluster. Its existence is suggested by indirect evidence, like the gravitational effects that it produces on the ordinary matter.

A cyclone is a closed, rotating wind. Cyclones rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
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.
A large area of low atmospheric pressure, characterised by inward-spiralling winds. A " low".
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.
A large area of low atmospheric pressure, characterized by inward-spiraling winds. A low.
An atmospheric cyclonic circulation closed circulation. A cyclone's direction of rotation (counterclockwise in the Northern Hemisphere) is opposite to that of an anticyclone. While modern meteorology restricts the use of the term cyclone to the so-called cyclonic-scale circulations, it is popularly still applied to the more or less violent, small- scale circulations such as tornadoes, waterspouts, dust devils, etc. (which may in fact exhibit anticyclonic rotation), and even, very loosely, to any strong wind. The first use of this term was in the very general sense as the generic term for all circular or highly curved wind systems. Because cyclonic circulation and relative low atmospheric pressure usually coexist, in common practice the terms cyclone and low are used interchangeably. Also, because cyclones are nearly always accompanied by inclement (often destructive) weather, they are frequently referred to simply as storms. See tropical cyclone, extratropical cyclone; compare trough.
In meteorology, a cyclone is an area of low atmospheric pressure characterised by inward spiraling winds that rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth. Since the generic term covers a wide variety of meteorological phenomena, such as tropical cyclones, extratropical cyclones, and tornadoes, meteorologists rarely use it without additional qualification.
Cyclone is a game for the Sinclair ZX Spectrum 48K computer, released by Vortex Software in 1985 . It was written by Costa Panayi who also coded Tornado Low Level, Android, Android 2, Highway Encounter and Revolution.
