A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .
A tropical cyclone differs from a hurricane or typhoon based only on geographic location. [50] A tropical cyclone is fundamentally different from a mid-latitude cyclone. [ 51 ] A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean , a typhoon occurs in the northwestern Pacific Ocean, and a tropical cyclone ...
The Great Red spot on Jupiter is considered as an Anticyclone storm system. [1] Anticyclonic cloud system taken above the Pacific Ocean by the STS-41-B crew.. An anticyclonic storm is a storm with a high-pressure center, in which winds flow in the direction opposite to that of the flow above a region of low pressure. [2]
Comparison between extratropical and tropical cyclones on surface analysis. There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. [18] A cyclone's center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region. [18]
Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
What are the differences between a hurricane, typhoon, and cyclone? Hurricane: Used to describe a storm in the Atlantic and Northeast Pacific. Typhoon: Used to describe a storm in the Northwest ...
Sir Francis Galton first discovered anticyclones in the 1860s. High-pressure systems are alternatively referred to as anticyclones. Their circulation is sometimes referred to as cum sole. Subtropical high-pressure zones form under the descending portion of the Hadley cell circulation. Upper-level high-pressure areas lie over tropical cyclones ...
[1] [2] This does not mean that the position and the intensity of this anticyclone are permanent, but just that there is an anticyclone on the maps describing the average monthly pressure. This area of high pressure is part of the great subtropical belt of anticyclones called the subtropical ridge.
