Typhoon Xuanlannuo continued to rain in the northeast of China. Why does it lead to the reappearance of high temperature in South China?

This is because southern China is still controlled by tropical pressure. When the typhoon leaves the south, the southern region will be controlled by tropical pressure again, and then there will be severe high temperature.

Since China entered the summer, some cities in the south of the Yangtze River have been in extremely hot weather for a long time. This has also directly led to serious drought in some coastal cities, which has seriously affected the daily life of residents. However, with the arrival of the typhoon, some cities in the southeast coast experienced short-term cooling and precipitation. It has greatly alleviated the impact of drought and high temperature weather, but only for a short time.

Typhoon? What about Xuan? Continue north, there is heavy rain in the northeast. This year, Typhoon 1 1 did not directly land on the southeast coast, but passed by in the East China Sea. The scope of influence is very limited, and only Jiangsu, Zhejiang and Shanghai are affected by this typhoon. There is a short period of cooling and rainy weather. After the typhoon moved to the northeast, the cities in the middle and lower reaches of the Yangtze River experienced high temperature above 35 degrees Celsius.

The middle and lower reaches of the Yangtze River are still controlled by tropical pressure. The reason why there will be high temperature weather in the middle and lower reaches of the Yangtze River, especially after the typhoon disappears. In the final analysis, it is because the middle and lower reaches of the Yangtze River are still controlled by tropical pressure. The tropical air pressure is still greater than the cold pressure zone in the northwest, so the cold air in Siberia can't go south for the first time, affecting the coastal areas.

Extreme weather has appeared all over the world this year. In fact, this extreme weather does not only happen in our region. Extremely abnormal weather has also appeared all over the world. According to the latest news, high temperatures above 40 degrees Celsius have appeared in all parts of the United States and Europe. Moreover, the temperature is still rising, and there is even a very serious drought and water shortage in Europe and America.
