What is the meaning of meteorological subtropical high?

Meteorological subtropical high is subtropical high.

In the subtropical regions of the southern and northern hemispheres, a high pressure belt along the latitudinal circle is often maintained, which is called the subtropical high pressure belt. Because of the land and sea distribution, the subtropical high zone is often divided into several high-pressure units with closed centers, which are called subtropical high.

The subtropical high is elliptical, and its long axis is roughly parallel to the latitude circle. It is a large-scale and continuous warm and deep planetary scale weather system (the warm center and the high pressure center do not necessarily coincide completely). It is the center of atmospheric activity that controls tropical and subtropical regions, and it is one of the important members of atmospheric circulation. Because the subtropical high occupies a vast space and is stable and inactive, its maintenance and activity play an important role in the transport and balance of water vapor, heat, energy and momentum between the low-latitude region and the middle-high latitude region, and have a great influence on the low-latitude circulation and weather changes.
