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.

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.

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. There are several favorable environmental conditions that must be in place before a tropical cyclone can form. They are:

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 · Tropical cyclones are also called hurricanes or typhoons, depending on the region. 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.

2017年9月6日 · The main parts of a tropical cyclone are the rainbands, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern in the northern hemisphere (clockwise in the southern hemisphere) and out the top in the opposite direction. In the very center of the storm, air sinks, forming an "eye" that is mostly cloud-

4 天之前 · Tropical cyclones are one of the biggest threats to life and property. As defined by the World Meteorological Organization (WMO), a tropical cyclone is a rotating storm originating over a tropical ocean basin that has a low pressure center (the eye).

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.

Tropical cyclones are low pressure systems that form over warm tropical waters. They typically form when: the sea surface temperature is above 26.5 °C. Tropical cyclones can continue for many days, even weeks. They may follow quite erratic paths. A tropical cyclone often loses energy and breaks up when it moves:
