The southern pole's cyclone-like storm is roughly the size of Europe. In addition, the southern polar vortex is constantly changing shape but the cause is still unknown. [4] In 1979, NASA's Pioneer Venus observed a double vortex cyclone at the north pole. There haven't been many more close-up observations of the north pole since Pioneer Venus.
An upper tropospheric cyclonic vortex is a vortex, or a circulation with a definable center, that usually moves slowly from east-northeast to west-southwest and is prevalent across Northern Hemisphere's warm season. Its circulations generally do not extend below 6,080 metres (19,950 ft) in altitude, as it is an example of a cold-core low.
The space hurricane was characterized by a cyclone-like auroral spot with multiple spiral arms, due to precipitating electrons, strong circular plasma vorticity with zero horizontal flow at its center (the equivalent of the eye of an atmospheric hurricane), a negative-to-positive bipolar magnetic structure (showing a circular magnetic field ...
The central dense overcast, or CDO, of a tropical cyclone or strong subtropical cyclone is the large central area of thunderstorms surrounding its circulation center, caused by the formation of its eyewall. It can be round, angular, oval, or irregular in shape. This feature shows up in tropical cyclones of tropical storm or hurricane strength.
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.
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]
Cyclone Chido made landfall on Saturday night with winds reaching over 200kph, Meteo-France said, causing damage to housing, government buildings and a hospital, and leaving at least 11 people dead.
