WHAT DO YOU MEAN BY CYCLONES AND ANTI-CYCLONES?

Question

IS IT RELATED TO SEA OR OCEAN?

Answer 1

The term cyclone, in common use, is sometimes applied to a tornado.

In the science of meteorology, however, the term has a different meaning.

For meteorologists, a cyclone — and its counterpart, an anticyclone is a large-scale system of air circulation in the atmosphere in the zones between the equator and either of the poles. It can be considered as either producing or resulting from differences in air pressure in those zones.

In a cyclone the central air pressure is lower than that of the surrounding environment, and the flow of circulation is clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere. Cyclones are also characterized by low-level convergence and ascending air within the system.

An anticyclone system has characteristics opposite to that of a cyclone. That is, an anticyclone's central air pressure is higher than that of its surroundings, and the airflow is counterclockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere. Anticyclones are usually characterized by low-level divergence and subsiding air.

Cyclones may be of various types and these are known by different names in different parts of world.e.g;

Cyclones in the Indian Ocean;

Hurricanes in the West Indies;

Tornadoes in the U.S;

Typhoons in the China Seas;

Willy Willies in the west coast of Australia.

One type of cyclone called the Tropical Cyclone have got a role of oceans in their formation and intensity.

Tropical Cyclones are low pressure systems that form over warm tropical waters and have gale force winds (sustained winds of 63 km/h or greater and gusts in excess of 90 km/h) near the centre.

Warmer seas accounted for 40% of a dramatic surge in cyclones in the Atlantic from the mid-1990s, say UK researchers.

Answer 2

In meteorology, a cyclone is an area of low atmospheric pressure characterized by inward spiraling winds that rotate counter clockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth.

In meteorology, an anticyclone (that is, opposite to a cyclone) is a weather phenomenon in which there is a descending movement of the air and a high pressure area over the part of the planet's surface affected by it. Anticyclonic flow spirals in a clockwise direction in the Northern Hemisphere and counter-clockwise in the Southern.

Answer 3

These terms are related to the atmosphere.

The wind in a cyclone circulates around the centre in a cyclonic direction, meaning in the same sense as the rotation of the earth... and the other way in an anticyclone.  

If you rememer it that way you don't have to keep referring to hemispheres and clocks.

Answer 4

CYCLONIC AND ANTI-CYCLONIC winds in these storms give them their names.  The term "cyclone" refers to storms that are cyclonic in rotation, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere.

Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low pressure area).

Cyclogenesis is the opposite of cyclolysis, and has an anticyclonic (high pressure system) equivalent which deals with the formation of high pressure areas—Anticyclogenesis.
