Winds that blow in and around a cyclone, that is counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere.
DAILY MEAN ...
This disturbance is characterized by distinct cyclonic flow, a pocket of cold air, and sometimes a jet streak. These features make the air aloft more unstable and conducive to clouds and precipitation.
Other phenomena with cyclonic flow may be referred to by this term, such as dust devils, tornadoes, and tropical and extratropical systems. The opposite of an anticyclone or a high pressure system.
Instead of flowing down the gradient, the air tends to flow perpendicular to the air-pressure gradient and forms a cyclonic flow. This is an example of a more general case of geostrophic flow in which air flows along isobars.
"Cyclogenesis" may refer to the birth of a cyclone or the intensification of cyclonic flow (counterclockwise circulation) around a low pressure system. Typically the pressure gradient increases (central pressure drops), winds strengthen, and clouds become more pronounced during this phase.
A disturbance in the upper atmospheric flow pattern which is usually associated with clouds and precipitation. This disturbance is characterized by distinct ~, a pocket of cold air, and sometimes a jet streak.
Vorticity - Spin of the air indicating rotation. Positive vorticity is ~, while negative vorticity is anticyclonic.
The circulation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Also called a low pressure system and the term used for tropical cyclone in the Indian Ocean . Other phenomena with ~ may be referred to as dust devils, tornadoes, ...
Hurricanes generally seem to ride on the anticyclonic flow of the large oceanic highs, "recurving" to accompany them along coasts to the west. However, the paths of hurricanes are highly unpredictable for individual storms.
