A tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and flooding rain. [45] A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. [45]
This true-color image of the storms was made from observations collected by alternating passes of the Aqua and Terra satellites. The cyclones pictured are (west to east) Gerry, Hape, Isha, and Fiona of the 2003 Southwest Indian cyclone season. Terra satellite passed over this area in the morning, moving east to west, and contributing the first ...

A photo taken on December 15, 2024 shows a pile of debris of metal sheets, wood, furniture and belongings after the cyclone Chido hit France's Indian Ocean territory of Mayotte.
The orphaned MCV can become the seed of the next thunderstorm outbreak. An MCV that moves into tropical waters, such as the Gulf of Mexico, can serve as the nucleus for a tropical cyclone. An example of this was Hurricane Barry in 2019. MCVs can produce very large wind storms; sometimes winds can reach over 100 miles per hour (160 km/h).
A tropical cyclone tracking chart is used by those within hurricane-threatened areas to track tropical cyclones worldwide. In the north Atlantic basin, they are known as hurricane tracking charts . New tropical cyclone information is available at least every six hours in the Northern Hemisphere and at least every twelve hours in the Southern ...
