Subtropical high pressure belt

from Wikipedia, the free encyclopedia
The subtropical high pressure belt is close to the ground in the horse latitudes , between the Ferrel cell and the Hadley cell .

The subtropical high pressure belt (also subtropical-marginal tropical high pressure belt ) is an imaginary and idealized zone in the subtropics , which experiences constant high air pressure due to the planetary circulation in the Hadley cell , with which thermal high pressure areas are formed. The high pressure belt spans the globe on both hemispheres in the area of ​​the subtropical front and is caused by the fact that the air that has risen, expanded and thus cooled in the Innertropical Convergence Zone (ITC) is now compressed again by sinking after being transported to the polar direction through the Antipassat . This compression heats the air dry adiabatically and the absorption capacity for water ( air humidity ) increases. The uptake of water creates arid areas on the land surface of the earth in the area of ​​the subtropical high pressure belt (more precisely the tropical-subtropical arid areas ). The subtropical high pressure belt is latitudinally between 20 ° and 40 ° and moves in the course of the year in a north-south direction, so it is dynamic.

The most prominent and most relevant example of a high in this belt for Central Europe is the dynamic Azores high , which is constantly re-emerging.
