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]
Tropical cyclones typically began to weaken immediately following and sometimes even prior to landfall as they lose the sea fueled heat engine and friction slows the winds. However, under some circumstances, tropical or subtropical cyclones may maintain or even increase their intensity for several hours in what is known as the brown ocean ...
The process in which an extratropical cyclone undergoes a rapid drop in atmospheric pressure (24 millibars or more) in a 24-hour period is referred to as explosive cyclogenesis, and is usually present during the formation of a nor'easter. [2] Similarly, a tropical cyclone can undergo rapid intensification.
The term cyclone was coined by Henry Piddington of the British East India Company to describe the devastating storm of December 1789 in Coringa, India. [5] A cyclone forms around a low-pressure area. Anticyclone, the term for the kind of weather around a high-pressure area, was coined in 1877 by Francis Galton. [6]
Cyclone has origins in ancient Greek, the administration said. It likely came from from either κύκλος ( kúklos , “circle, wheel”) or κυκλόω ( kuklóō , “go around in a circle ...
Bomb cyclones form when the conditions at the surface and at the jet stream level are ideal for the storm to intensify. The jet stream is a narrow band of strong winds in the upper atmosphere.
Out of all these tropical cyclones, Typhoon Tip had the lowest atmospheric pressure measured in a tropical cyclone, at 870 mbar (25.69 inHg). It is the third image in the first row. This is a list of the most intense tropical cyclones as measured by minimum atmospheric pressure at sea level.
Cyclogenesis is the development and strengthening of cyclonic circulations, or low-pressure areas, within the atmosphere. [3] Cyclogenesis is the opposite of cyclolysis, and has an anticyclonic (high-pressure system) equivalent which deals with the formation of high-pressure areas—anticyclogenesis. [4]
