Why is it so hot in Henan

The cause of high temperature weather is mainly influenced by warm and low pressure on the ground, which leads to sunny, hot and little rain in most parts of Henan. Coupled with the influence of short-wave radiation of the sun during the day, the weather is dry, which is conducive to the gradual increase of ground temperature.

At the same time, controlled by the high altitude ridge, descending flow prevails in Henan, which has a certain sinking and warming effect, and high temperature weather appears under the joint action of radiation warming and sinking warming.
