Why is the temperature in Henan so high this year?

The reasons are as follows:

The reason for this high temperature is that Henan is being controlled by the continental high pressure ridge, and downdrafts prevail. At this time, the air on the ground will be pressurized, not only In this way, the continuous compression of air here will also lead to a rapid increase in energy. The entire surface is like a "pressure cooker", heating and pressurizing.

Under the control of the continental high-pressure ridge, the air will be dry, making it difficult for moisture to condense into clouds and fog. The permeability of the atmosphere is very strong, and sunlight can directly reach the surface. This will cause solar radiation to directly reach the ground. Radiation has a strong warming effect, causing persistent high temperature weather in many places in Henan.

Characteristics

In fact, in May and June every year, high temperatures are prone to occur in the north controlled by the continental high pressure ridge, but the number of days with high temperatures is less in previous years. Among them, extreme high temperatures occur There are fewer days.

This year, extreme hot weather has occurred in many places in Henan, especially when the temperature has been above 35°C for many days. In our country, hot weather above 35°C is considered a high temperature weather, and the duration is more than 3 days. "High temperature heat wave".
