What's the weather like in the area controlled by subtropical high?

Generally, the areas controlled by subtropical high are often sunny and hot.

The eastern part of the subtropical high is a strong subsidence movement area, and the descending airflow will become warmer due to thermal compression, and there will be continuous sunny and hot weather in the control area. The subtropical high zone is located in the subtropical region near 20 to 30 north latitude. Its formation is mainly due to the updraft in the equatorial low pressure zone, which flows over the polar regions under the influence of the pressure gradient force.

Due to the strong solar radiation in the equatorial region, the air in this region rises and will flow to the polar direction after reaching high altitude. The geostrophic force produced by the earth's rotation makes the airflow deviate constantly, with the northern hemisphere turning right and the southern hemisphere turning left. With the increase of latitude, the geostrophic deflection changes greatly, which makes the airflow in the subtropical region basically flow from west to east.

Introduction of subtropical high

Subtropical high is an important member that restricts the change of atmospheric circulation and is one of the persistent large-scale weather systems in subtropical areas. Subtropical high plays an important role in the transport of water vapor, heat and energy between middle and high latitudes, and is the main weather system in summer.

The subtropical high will change with the seasons, and the intensity and position of the subtropical high belt will also change obviously with the seasons. The subtropical high is oval, and its long axis is roughly parallel to the latitude circle, which is a large and lasting warm deep-scale weather system. It is the center of atmospheric activity that controls tropical and subtropical regions, and it is one of the important members of atmospheric circulation.
