An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central ... between a high-pressure system and a low-pressure system ...
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 .
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]
The Azores High also known as North Atlantic (Subtropical) High/Anticyclone or the Bermuda-Azores High, is a large subtropical semi-permanent centre of high atmospheric pressure typically found south of the Azores in the Atlantic Ocean, at the Horse latitudes. It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low.
The North Pacific High is a semi-permanent, subtropical anticyclone located in the northeastern portion of the Pacific Ocean, located northeast of Hawaii and west of California. It is part of the great belt of anticyclones known as the subtropical ridge .
[14] [15] High-pressure systems are alternatively referred to as anticyclones. On weather maps, high-pressure centers are associated with the letter H in English, [16] or A in Spanish, [17] because alta is the Spanish word for high, within the isobar with the highest pressure value. On constant pressure upper level charts, it is located within ...
A North American High moves eastward across the continent, [1] often in the company of one or more low-pressure cells or cyclones.The cold, dense air does not extend usually above 3 km (1.9 mi) and is lower than the Canadian Rockies mountain range. [2]
The low, sharp inversion can lead to areas of persistent stratocumulus or stratus cloud, colloquially known as Anticylonic gloom. Anticyclones generally bring fair weather and clear skies as the dynamics of an anticyclone lead to downward vertical movement which suppresses convective activity and generally lowers the mean relative humidity, in ...
