Why China s three major furnaces are in the Yangtze River basin

The Yangtze River basin is controlled by the western Pacific subtropical high. Therefore, there are many high temperature and high humidity weather. In addition to meteorological factors such as being controlled by the subtropical high in summer.

Chongqing, Wuhan and Nanjing have large populations and are all industrial cities, and the heat island effect is also an important reason.

Moreover, they are all deep inland, the heat increasing effect is relatively high, and there is no sea breeze, relying on the rivers and lakes to cause the local air pressure to be too high, and various reasons have created the three major furnaces in the Yangtze River Basin

Chongqing, Wuhan and Nanjing, on the Yangtze River, are known as China's "three major furnaces".

The high and long duration of summer temperatures, coupled with the small diurnal temperature range, makes it difficult to feel the heat even though the minimum temperature remains around 25 at night. There are three reasons why it's so hot:

One mu is in the drought period, the sun is like fire, and the warming effect of the subtropical Tongling attack under the control of high pressure produces air flow.

Second, it is the terrain of the river valley and the low altitude that make it like the bottom of a pot, and it is difficult to dissipate heat on the ground.

Third, there are many paddy fields along the river, the water network is dense, and the evaporation of the water surface increases the air humidity.

Known as the "three major furnaces" on the Yangtze River in China, Wuhan, Chongqing, and Nanjing

So the answer is: Wuhan; Chongqing; Nanjing

Chongqing, Wuhan, Nanjing.

Judging from the number of days with high temperature above 35, along the Yangtze River, there are 20 days in Anqing and 20 days in Hangzhou, which are more than those in Nanjing; Jiujiang has 25 days, and Huangshi has more days than Wuhan; There is a day in Fuling, there is a day in Wanxian, and it is also above Chongqing. There are even more high-temperature "stoves" outside the Yangtze River, for example, there are days of hot days in Guixi, Jiangxi, Hengyang, Hunan, and Kaixian, Sichuan.

Nanjing, Wuhan and Chongqing three major furnaces are indeed very hot, the average temperature in July is about 33, the extreme maximum temperature has been reached, the high temperature lasts for a long time, the number of hot days higher than 30 every year, the average is more than 70 days, and from morning to night, the temperature changes little, not only hot during the day, but also unbearable at night. The main reason for the formation of the three major furnaces along the Yangtze River is that the upper altitude is controlled by the subtropical high pressure zone in summer. The second is the influence of the terrain.

Chongqing, Wuhan and Nanjing are all in the valleys of the Yangtze River basin at low altitudes, and the topographical characteristics of the valleys are like the bottom of a pot, surrounded by mountains, and it is difficult to dissipate heat on the ground, so that the temperature continues to rise. The third is that these places have a dense network of paddy fields, a lot of water vapor, high humidity, and it is not easy for the human body to evaporate after sweating, and the heat dissipation efficiency of sweating is greatly reduced, and the high temperature and high humidity make people feel stuffy. In fact, these three furnaces are not yet hot.

Chongqing in Chongqing, Wuhan in Hubei, Nanjing in Jiangsu.

China's "three major furnaces" are in the three famous cities of Chongqing, Wuhan and Nanjing along the Yangtze River. It's very hot all day long, even the lowest temperature is very hot. Most days the lowest temperature is around 28.

According to the research of the Meteorological Observatory, the highest temperature of 35 days in a day is called "hot days", and the number of hot days in the three cities every year is as many as 15 35 days, and there are often 37 "hot days", among which Chongqing's hot days are the most, in history, the highest temperature in the three cities is mostly above 40, therefore, there are "three furnaces" said. Why are these three places so hot?

First, in July and August every year, as soon as the plum rain in the middle and lower reaches of the Yangtze River passes, the high pressure temperature controls here, making it difficult to generate clouds and rain in dry weather caused by the downward movement of the air flow, and the surface temperature is very high. It has been measured that on very hot days, the maximum temperature on the ground can reach 65 70.

Second, the three famous cities are located in the valley area of the Yangtze River basin. The low altitude, ground temperature and heat are not easy to dissipate, so that most of the heat is preserved; In addition, the air flows from the high places to the valleys, and not only does it not form clouds and rain, but the temperature becomes higher and higher. At the same time, the rice fields along the Yangtze River are vertical and horizontal, the river network is dense, and the air has a lot of oxygen content and high humidity. The high temperature and humidity climate makes it difficult for human sweat to evaporate, making people feel very stuffy.

Thirdly, because there is a lack of cool breeze here in summer. The air flow is mainly sinking, and the atmosphere is very stable, without even a hint of wind, which speeds up the hot atmosphere here.

In this way, these three cities are really well-deserved "furnace cities".

The three big cities in the Yangtze River basin - Nanjing, Wuhan and Chongqing are known as China's "three furnaces" The average number of hot days in the three cities is 48-68 days, the number of hot days is 17-34 days, and the number of hot days is also as many as 3-14 days

Therefore, c

Chongqing, Wuhan and Nanjing are all in the valleys of the Yangtze River basin at low altitudes, and the terrain of the valleys is like the bottom of a pot, surrounded by mountains, and it is difficult to dissipate heat on the ground, so that the temperature continues to rise. The third is that these places have a dense network of paddy fields, a lot of water vapor, high humidity, and it is not easy for the human body to evaporate after sweating, and the heat dissipation efficiency of sweating is greatly reduced, and the high temperature and high humidity make people feel stuffy.

If you don't put it together, you can't see it at all, and the higher the resolution, the greater the power consumption.

The soil is under the action of natural or man-made factors.

At that time, the middle and lower reaches of the Yangtze River basin were Chongqing, Wuhan, and Nan.

It's just that it's hot.

Because they are all near the Yangtze River basin.

This is the most primitive distribution of geography without why.

This is because of the special geographical location.
