What are the climatic characteristics under the control of subtropical high?

The weather in the control area of subtropical high pressure zone is characterized by high temperature and little rain. Subtropical high plays an important role in the transport and balance of water vapor, heat and energy between middle and high latitudes, and is an important system of atmospheric circulation.

The subtropical high zone is located in the subtropical zone near 20-30 north and south latitudes. Its formation is mainly because the updraft in the equatorial low pressure area rises to the sky and is affected by the pressure gradient force. Due to the influence of land and sea distribution, in summer, the subtropical high area is often cut off by the continental thermal low pressure and only stays in the ocean. Subtropical high is prevalent in downdraft, and the climate is generally dry and rainy.

Extended data

The subtropical high belt is closely related to the weather changes in the northwest Pacific and East Asia. The western Pacific subtropical high is generally located in the ocean, but its western end can often reach the coast of China, especially in summer, and even reach the land in the west. If you pay attention to the news related to meteorology, you will find that the persistence of intense heat, the change of rain belt and the activity of typhoon are mostly inseparable from the change of subtropical high.

From the point of view of meteorological specialty, downward flow prevails near the ridge line of subtropical high. The atmosphere is generally dry and the pressure gradient is small, so the wind is very small. In this state, solar radiation can reach the ground more, making the ground and near-earth atmosphere get more heat, and the atmospheric temperature rises obviously.
