The intensity of a tropical cyclone appears to have little bearing on its potential for rainfall over land, but satellite measurements over the last several years show that more intense tropical cyclones produce noticeably more rainfall over water. Flooding from tropical cyclones remains a significant cause of fatalities, particularly in low ...
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
Rainbands in advance of warm occluded fronts and warm fronts are associated with weak upward motion, [1] and tend to be wide and stratiform in nature. [2] In an atmosphere with rich low level moisture and vertical wind shear, [3] narrow, convective rainbands known as squall lines form generally in the cyclone's warm sector, ahead of strong cold fronts associated with extratropical cyclones.

A crowd gathers the morning of Sept. 28 at the West Asheville Fire Station on Haywood Street where there is Wi-Fi. But the fire station is not handing out water. Why did Helene bring so much rain?
Tropical cyclones form as a result of significant convective activity, and are warm core. [11] Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. [13] Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. [14]
Tropical cyclone – storm characterized by a large low-pressure center and numerous thunderstorms that produces strong winds and heavy rain. Tropical cyclones develop or strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air.
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapor contained ...
