Tropical cyclone: tropical cyclone, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain also called typhoons and hurricanes, cyclones strike regions as far apart as the gulf coast of north america, northwestern australia, and eastern india.

Tropical cyclones description of tropical cyclones a tropical cyclone is a particular type of low pressure system that occurs in the summer months near northern australia and composes over warm tropical waters.
The strongest tropical cyclone recorded in the north indian ocean is the 1999 odisha cyclone, with 3-minute sustained winds of 260 km/h (160 mph) and a minimum pressure of 912 hpa (2693 inhg) storms with an intensity of 950 hpa (2805 inhg) or less are listed. To a first approximation a tropical cyclone is like a heat engine - it derives its energy from the heat that is released when water vapour that has been evaporated from the ocean surface (assisted by high winds and low pressure) condenses in the middle of the atmosphere.
Tropical cyclones thus commonly develop in areas near, but not at the equator, as shown in the diagram below as they move across the oceans their paths are steered by the presence of existing low and high pressure systems, as well as the coriolis force.

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (/ ˈ h ʌr ɪ k ən, -k eɪ n /), typhoon (/ t aɪ ˈ f uː n. Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain drawing energy from the sea surface and maintaining its strength as long as it remains over warm water , a tropical cyclone generates winds that.
A tropical depression is a system with low pressure enclosed within few isobars and the wind speed is 33 knot or 61 tens and it lacks a marked circulation a tropical storm is a system with several closed isobars and a wind circulation of 115 kms. In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure the largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale)warm-core cyclones such as tropical cyclones and subtropical. Definitions 1 what is a tropical cyclone a tropical cyclone is defined as a non-frontal low pressure system of synoptic scale developing over warm waters having organised convection and a maximum mean wind speed of 34 knots or greater extending more than half-way around near the centre and persisting for at least six hours. Geography exam topics quiz- tornadoes, cyclones, weather etc 43 questions | by lauranewman tropical cyclones are intense low pressure systems b the walker circulation is an atmospheric circulation of air at the equatorial pacific ocean, responsible for creating ocean upwelling off the coasts of saudi arabia and adis ababatrue or.
Cyclone is a system of low atmospheric pressure in which the barometric gradient is steep winds circulate, blowing inwards in an anticlockwise direction in the northern hemisphere and clockwise direction in the southern hemisphere.
Exam 3 chapter 10 study tropical cyclones form over warm tropical or subtropical ocean water, typically between 5 and 20 degrees latitude they are not associated with fronts and have warm central cores the second mechanism is the low atmospheric pressure in the storm that sucks up the sea surface the shape of a coastline also. Physical geography exam 3 study play a center of low atmospheric pressure where surface air converges into a spiral and is uplifted to the upper troposphere associated with cloudy, rainy weather - tropical cyclone: can be hurricanes, or typhoons, tropical and subtropical zones - tornado midlatitude cyclone.
