What is the weather controlled by subtropical high?

The natural boundary between subtropical and warm temperate climate zones in China: Qinling Mountains. Areas controlled by subtropical high are often sunny and hot. The subtropical high zone is located in the subtropical zone near the latitude of 20 ~ 30.

Its formation is mainly due to the fact that the updraft from the equatorial low pressure zone reaches the sky and flows over the polar regions (near-surface high pressure region and upper low pressure region) under the influence of the pressure gradient force. Due to the effect of geostrophic bias, the direction of atmospheric movement over latitude is close to the latitude circle of 20 ~ 30.
