What are the three stoves in China?
A stove refers to a hot city in summer. It first began in the Republic of China, when Chongqing, Wuhan, Nanjing and other places in the middle and lower reaches of the Yangtze River were hot in summer, so it was called "three stoves".
During the Republic of China, there was a high temperature area in the middle and lower reaches of the Yangtze River in China in summer, including Nanjing, Wuhan and Chongqing. The highest temperature in China and Japan exceeds 30℃ for more than 70 days in a year, and there have been high temperature weather above 40℃, so people also call these three cities "three stoves". It doesn't mean the unusually high temperatures in these three cities, but as well-known cities, their enthusiasm is easier to be remembered and publicized by literati in past dynasties.
Form a background:
During the Republic of China, the three stoves in Nanjing, Wuhan and Chongqing were really hot. The average maximum temperature in the hottest month is about 32 ~ 34℃, and the extreme maximum temperature is 39.6 ~ 43.0℃. The high temperature lasts for a long time, and the average number of hot summer days above 30℃ is more than 70 days per year, and the temperature changes little from morning till night, not only during the day, but also at night.
The main reason for the formation of the three furnaces along the Yangtze River is that the high altitude in summer is controlled by the subtropical high pressure area; The second is the influence of topography. Chongqing, Wuhan and Nanjing are all located in the lower Yangtze River basin. The topography of the valley is like the bottom of a pot, surrounded by mountains, and the ground is difficult to dissipate heat, which makes the temperature rise continuously. Third, these places are densely covered with rice fields, with a lot of water vapor and high humidity. People are not easy to evaporate after sweating, and the heat dissipation efficiency of sweating is greatly reduced. High temperature and humidity make people feel sultry.
