Cyclonic storms are common on giant planets, such as the Small Dark Spot on Neptune. [64] It is about one third the diameter of the Great Dark Spot and received the nickname "Wizard's Eye" because it looks like an eye. This appearance is caused by a white cloud in the middle of the Wizard's Eye. [8] Mars has also exhibited cyclonic storms. [7]
A high-speed rotating (air)flow is established within a cylindrical or conical container called a cyclone. Air flows in a helical pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top.
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]
Mesoscale ocean eddies are characterized by currents that flow in a roughly circular motion around the center of the eddy. The sense of rotation of these currents may either be cyclonic or anticyclonic (such as Haida Eddies). Oceanic eddies are also usually made of water masses that are different from those outside the eddy.
In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or ...
A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in the moist air.
Airflow around troughs and ridges in upper troposphere. Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: [ 2 ] ahead of an upper-ridge, the airflow that comes from the polar regions and brings cold air.
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.
