It is known as the three major furnace cities in our country

In the middle and lower reaches of the Yangtze River in China, there is a summer high temperature area, such as Nanjing, Wuhan and Chongqing, the daily maximum temperature exceeds 35 days for more than 20 days in a year, and there has been more than 40 high temperature weather, so people also call these three cities "three furnaces".

China's hot pole Turpan Basin, China's current extreme maximum temperature record was observed on July 13, 1975. However, it is small in size, small in population, and hot but not stuffy. Therefore, in the hottest summer of the year, the greatest impact on the life and work of our people is not in Turpan, but in the Yangtze River basin, which has a vast area and a large population

Nanjing, Wuhan and Chongqing.

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. 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.

So why are Nanjing, Wuhan and Chongqing called the three "furnaces"? Maybe it's because they're well-known big cities, and they've been the result of the propaganda of many literati and writers in history.

Wuhan. China's three major furnace cities --- Nanjing, Wuhan and Chongqing.

The three cities are located at latitudes near the direct point of the summer sun in the Northern Hemisphere, so it is guessed that it will be very hot. In fact, it's not just these three, as long as it's at this latitude, Sui Xianxun is the northern latitude.

Around 30 degrees Celsius, it will be hotter, if it rains, it will be better, if it doesn't, these places will be hotter than other latitudes on the earth.

Similarly, the Southern Hemisphere near 30 degrees south latitude will have hotter summers in the Southern Hemisphere.

The four major furnaces in the early days were Chongqing, Wuhan, Nanchang and Changsha. The new four major furnaces are Chongqing, Wuhan, Hangzhou, and Nanchang. According to the latest list released by the National Climate Center of the China Meteorological Administration, the top 10 provincial capitals in summer are:

Chongqing, Fuzhou, Hangzhou, Nanchang, Changsha, Wuhan, Xi'an, Nanjing, Hefei, Nanning.

The hot weather is generally concentrated in the Yangtze River basin in southern China and the Huanghuai region in northern China. The term "stove" first reflected the intuitive feeling of the public, and for a long time there was no clear definition and standard.

After the 21st century, furnace cities began to take the heat index, the number of high temperature days, the number of consecutive lead old high temperature days, and the average maximum and minimum temperature in summer as the factors taken into account for sail rental.

The definition of the furnace city is divided into record high temperature, human adaptability and continuous high temperature time, in terms of temperature, no one can compare with "Huozhou" Turpan, but in the humid south, especially in the middle and lower reaches of the Yangtze River cities, the hot and humid weather is more unbearable, among them, the mountain city of Chongqing, the river city of Wuhan, the stone city of Nanjing, the star city of Changsha, the hero city of Nanchang is the most.

Hello, I'm glad to answer for you, the following are the top 10 furnace cities in China according to the average temperature and high summer temperature: Urumqi: Urumqi is located in Xinjiang and is known as one of the furnace cities due to its dry climate and high altitude with extremely high summer temperatures.

Yinchuan: Yinchuan is the capital of Ningxia and is an inland city. Its summer heat is also quite amazing, and it is dry and rainy all year round.

Lanzhou: Lanzhou is located in Gansu Province, a city in the Hexi Corridor, with high summer temperatures and a dry climate. Xining:

Xining, the capital of Qinghai Province, also has relatively high summer temperatures due to its location in the highland region. Shenyang: Shenyang is an important city in Northeast China, and although the overall climate tends to be cold, there are still hot days in summer, so it can also be classified as one of the furnace cities in Ziga.

Nanjing: Nanjing, the capital city of Jiangsu Province, has a humid monsoon climate that leads to high summer temperatures, with frequent hot weather. Wuhan:

Wuhan is located in Hubei Province, with hot and humid summers and hot all year round. Chongqing is a large city in southwest China, and due to its geographical location and mountainous environment, it is known as the furnace city due to its high summer temperatures.

Chengdu: Chengdu is located in the Sichuan Basin, with high temperature and rain in summer, and is also a furnace city. Shenzhen:

Shenzhen is a coastal city in southern China, with hot and humid summers and hot all year round.
