The word, cyclone, in Greek, means: a twist. It is used in meteorology for every low-pressure core. The reverse, then, is called a high pressure: an anticyclone.
Cyclone is also the name we assign low pressure in the Indian Ocean to the hurricane storm. We tag them into the Pacific, typhoon.
Cyclones are like giant engines in which dry, moist air is used as fuel. Therefore they only develop over warm ocean waters near the equator. The dry, humid air rises upward from below the surface over the ocean. Since this air is going up and out of the atmosphere, less air is left below the atmosphere. Another way to mean the same thing is for the warm air to rise, creating a lower air pressure region below.
Higher air pressure air from nearby areas flows into the low pressure area. Then that "new" air becomes warm and humid, and also rises. As the warm air keeps on rising, the surrounding air swirls in to take its place. As the dry, humid air rises and cools off, clouds form the water in the air. The entire network of clouds and wind spins and develops, fuelled by the evaporating heat and water from the surface of the ocean.
Storms that spin counterclockwise to north of the equator. Storms spin in clockwise direction south of the equator. The disparity is due to the rotation of the Earth on its axis.
As the storm system rotates faster and faster a centered eye forms. In the eye it is very smooth and clear, with very low air pressure. The higher pressure air flows down into the eye from above.
The weather is named a "tropical storm" when the winds in the rotating system exceed 39 mph. And when the wind speeds exceed 74 mph, the storm is officially a "tropical cyclone," or hurricane.

Who gives the name of cyclone?
Tropical cyclones are usually assigned names as it helps track, locate, and report. They 're named after having steady 62 km / h winds. World Meteorological Organization committees select names. Typically, a cyclone is not renamed once named.
Hurricanes were named after saints for several hundred years. Australian meteorologist Clement Wragge started giving tropical cyclones female names in 1887. He spoke of names in literature and mythology. Usually when he used the names of men they were politicians he hated. By World War II cyclone names (Able, Baker, Charlie) were based on the phonetic alphabet. The U.S. began using phonetic names in 1953, and started using feminine names for such hurricanes. This began in 1978, when male and female names were used for storms in the Pacific. The practice was extended to the Gulf of Mexico and the Atlantic in 1979 for hurricanes.
