In meteorology, a cyclone (/ ˈsaɪ.kloʊn /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). [1][2] Cyclones are characterized by inward-spiraling winds that rotate about a ...

A cyclone is defined as a powerful storm containing strong winds and rains. It is formed when the warm and moist air rises making space for cool air in low-pressure areas.

2024年12月9日 · A cyclone is an atmospheric disturbance characterized by a low-pressure center and winds. Cyclones have names assigned to them for identification and tracking purposes. Wind speed and direction are attributes of cyclones that determine their intensity and impact. Learn about cyclone formation, structure, and classification systems.

2023年10月19日 · Called hurricanes when they develop over the North Atlantic, central North Pacific, and eastern North Pacific, these rotating storms are known as cyclones when they form over the South Pacific and Indian Ocean, and typhoons when they develop in …

2025年1月23日 · 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.

2025年1月31日 · 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.

2024年1月21日 · In meteorological terms, a cyclone is a large air mass that has the ability to rotate around a center of focus or a center of low atmospheric pressure. Cyclones are mainly associated with inwards spiraling winds that especially rotate around the low-pressure region.

A cyclone is the general term for a variety of low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes. The largest of these systems are extratropical cyclones and cold-core polar cyclones which lie on the synoptic scale with a horizontal length of 1000 km or more.

A cyclone is a huge revolving storm caused by very high speed winds blowing around a central area of very low pressure in the atmosphere. A cyclone is formed over warm sea-water and it is about 10 to 15 kilometres high. A cyclone revolves due …

A cyclone is a meteorological phenomenon characterized by a low-pressure system at its centre, accompanied by strong winds and heavy rainfall. This atmospheric disturbance can manifest in a variety of forms, with tropical cyclones and extratropical cyclones being the primary types.
