A tropical cyclone is an intense circular storm that originates over warm tropical oceans. It is also called a hurricane or a typhoon. It is characterized by low atmospheric pressure and heavy rain, and its winds exceed 119 km (74 miles) per hour.
Tropical cyclone - Formation, Paths, Impacts: A circulation system goes through a sequence of stages as it intensifies into a mature tropical cyclone. The storm begins as a tropical disturbance, which typically occurs when loosely organized cumulonimbus clouds in an easterly wave begin to show signs of a weak circulation.
Cyclone, any large system of winds that circulates about a centre of low atmospheric pressure in a counterclockwise direction north of the Equator and in a clockwise direction to the south. Cyclonic winds move across nearly all regions of the Earth except the equatorial belt and are generally.
Cyclogenesis, in meteorology, the process of extratropical cyclone development and intensification. Cyclogenesis is initiated by a disturbance occurring along a stationary or very slow-moving front between cold and warm air. This disturbance distorts the front into the wavelike configuration.
Because of information gathered by satellites observing Earth, we know that cyclones form in low pressure zones over warm intertropical seas. A tropical depression may intensify and evolve into a tropical storm, with even lower pressures and stronger winds.
Tropical cyclones can cause ocean waves to rise to 20 feet (6 meters) above their normal height. The large waves, called a storm surge, can flood coastal cities. Tropical cyclones get their energy from warmth and moisture that rise from the ocean surface.
A tropical cyclone, also called a hurricane or typhoon, is an intense circular storm that originates over warm tropical oceans. It is characterized by low atmospheric pressure, high winds, and heavy rain. A tropical cyclone draws energy from the sea surface.
Tropical cyclone - Damage, Wind, Rain: High winds cause some of the most dramatic and damaging effects associated with tropical cyclones. In the most intense tropical cyclones, sustained winds may be as high as 240 km (150 miles) per hour, and gusts can exceed 320 km (200 miles) per hour.
A storm surge accompanying an intense tropical cyclone can be as high as 6 metres (20 feet). Most of the surge is caused by friction between the strong winds in the storm’s eyewall and the ocean surface, which piles water up in the direction that the wind is blowing.
Extratropical cyclone, a type of storm system formed in middle or high latitudes, in regions of large horizontal temperature variations called frontal zones. Extratropical cyclones present a contrast to the more violent cyclones or hurricanes of the tropics, which form in regions of relatively.
