A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls.

A tropical cyclone is a warm-core low pressure system, without any front attached, that develops over the tropical or subtropical waters and has an organized circulation. These include hurricanes and typhoons.

2025年4月5日 · 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.

2023年9月8日 · Forecast/Advisories are issued on all Atlantic and eastern Pacific tropical and subtropical cyclones every six hours at 0300, 0900, 1500, and 2100 UTC (learn about UTC time). Special Forecast/Advisories may be issued at any time due to significant changes in …

2025年4月2日 · A tropical cyclone is a rapidly rotating storm that begins over tropical oceans, and they can vary in speed, size, and intensity. Tropical cyclones are the second-most dangerous natural hazards, after earthquakes.

A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).

2023年10月19日 · Tropical cyclones with an organized system of clouds, and thunderstorms with a defined circulation and maximum sustained winds of 38 mph (61 km/h) or less, are called "tropical depressions". Once the tropical cyclone reaches winds of at least 39 mph (63 km/h), they are typically called a "tropical storm" and ass

A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation. Tropical cyclones rotate counterclockwise in the Northern Hemisphere. They are classified as follows:

A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in

1 天前 · There are no tropical cyclones in the Central Pacific at this time. The Central Pacific hurricane season runs from June 1st through November 30th.
