National high temperature list: The difference between the coolest and the hottest is 17℃. Why is Chongqing the well-deserved "King of High Temperature"?

Since this summer, the whole country and even the world have been experiencing high temperature tests, and Chongqing in our country is the "king of high temperatures", so this situation will occur. First of all, from the topography of Chongqing, it is surrounded by It is a high mountain, and the middle area is very low. Such a terrain environment makes it difficult for heat to escape, which ultimately makes the high temperature weather here longer. Secondly, while Chongqing has a basin environment, it is surrounded by abundant water resources. A large amount of water evaporates and enters the atmosphere, making the temperature even hotter. In an extremely humid environment, it is difficult for the human body's own heat to dissipate. In addition, geographically speaking, Chongqing happens to be located in the Yangtze River Basin, which is ruled by subtropical high pressure every year. The weather is mainly sunny and clouds rarely appear. Ultimately, the sun is directly exposed and summers are hotter than other places.

1. Surrounded by mountains

Topographically speaking, Chongqing is purely a "basin" environment. It is surrounded by mountains. At the same time, the mountains are not just one place, but both inside and outside. Several levels of mountains. The main urban area of ??Chongqing is relatively low. Such a terrain makes it difficult for local high-temperature airflow to dissipate, so persistent high-temperature weather will form every summer.

2. The air humidity is high and therefore extremely hot

Chongqing has a lot of rain throughout the year, making the air humidity very high. At the same time, in addition to the Yangtze River, there are a large number of abundant hydropower resources around Chongqing. A large amount of water evaporates into the air every year, making the air hotter and muggier. In this humid environment, the body surface temperature will be higher and the body surface feeling will only be worse.

3. Few clouds can block the sun in summer

From a geographical perspective, Chongqing is located in the area dominated by subtropical high pressure in the Yangtze River Basin. That is to say, after the tropical air flow comes all the way from the south, it is blocked by the mountains and continues to descend under the high pressure. At the same time, Chongqing mainly has sunny days with few clouds in summer, which makes the direct sunlight severe and the temperature higher.
