An area of low pressure where winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere See anticyclone, wind
a violent rotating windstorm (meteorology) rapid inward circulation of air masses about a low-pressure center; circling counterclockwise in the northern hemisphere and clockwise in the southern
It is attended by high temperature, moist air, abundant precipitation, and clouded sky
A system of winds rotating around a center of low atmospheric pressure. A cyclone rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere (opposite to that of an anticyclone). Modern meteorology restricts the use of the term cyclone to the cyclonic-scale circulations. But, it is still applied popularly to the more or less violent, small-scale circulations such as tornadoes, waterspouts, and dust devils (which may in fact exhibit anticyclonic rotation), and even, very loosely, to any strong wind. Because cyclonic circulation and relative low atmospheric pressure usually coexist, in common practice the terms cyclone and low are used interchangeably. Also, because cyclones nearly always are accompanied by inclement (sometimes destructive) weather, they are frequently referred to simply as storms
an area of low pressure, with circulation counterclockwise in the northern hemisphere and clockwise in the southern hemisphere (See also anticyclone, Coriolis force, atmospheric pressure)
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,"
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
An area of low atmospheric pressure with converging and ascending air flows that rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere
This center moves onward, often with a velocity of twenty or thirty miles an hour
a large-scale circulation of winds around a central region of low atmospheric pressure, counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere
alternative name for a depression, an area of low atmospheric pressure A severe cyclone that forms in the tropics is called a tropical cyclone
An area of low atmospheric pressure characterized by rotating and converging winds and ascending air
A violent storm, often of vast extent, characterized by high winds rotating about a calm center of low atmospheric pressure
(meteorology) rapid inward circulation of air masses about a low-pressure center; circling counterclockwise in the northern hemisphere and clockwise in the southern
A Southeastern and Indian Ocean weather phenomenon that results in wind speeds of around 150 to 200 km/h
