What are the four big stove cities in China?

The traditional "stoves" are Nanchang, Chongqing, Wuhan and Changsha.

New "stoves" in Chongqing, Fuzhou, Hangzhou and Nanchang.

Sizao refers to the four hottest cities in China, and is the name of the four hottest cities in China in summer, which are generally concentrated in the Yangtze River basin in southern China and Huanghuai area in northern China.

It first started in the Republic of China, when Chongqing, Wuhan, Nanchang, Changsha and other places in the upper, middle and lower reaches of the Yangtze River were hot in summer, so it was called "four stoves". With the change of climate and the migration of weather stations, the list of cities is also changing.

The word "stove" first reflected the intuitive feelings of the public, and there was no clear definition and standard for a long time. After 2 1 century, the furnace city began to take heat index, high temperature days, continuous high temperature days, summer average maximum temperature and minimum temperature as consideration factors.

20 17 updated four new stoves, namely Chongqing, Fuzhou, Hangzhou and Nanchang. The National Climate Center of China Meteorological Bureau released the list, comprehensively analyzed the meteorological data of provincial capitals and municipalities directly under the Central Government of China, and released the situation of hot cities in summer in China to the public authority for the first time. The comprehensive analysis results are as follows.

The top 10 provincial capitals or municipalities in summer vacation are Chongqing, Fuzhou, Hangzhou, Nanchang, Changsha, Wuhan, Jinan, Xi 'an, Nanjing, Hefei and Nanning. Among them, Chongqing, Fuzhou, Hangzhou and Nanchang, which are in the forefront, have been named "the new four stoves" by many netizens.

Extended data

Reasons for the formation of the furnace:

Cities in the middle and lower reaches of the Yangtze River, such as Chongqing, Wuhan and Nanjing, are often sultry in summer, mainly controlled by the western Pacific subtropical high, and maintain high temperature and humidity for a long time. Especially in the middle and late July and early August, the subtropical high is generally maintained in the middle and lower reaches of the Yangtze River and its vicinity, making these areas sweltering.

With the rapid development of industrial economy, the unprecedented burning of fossil energy such as oil and coal, the emission of greenhouse gas carbon dioxide, the price reduction of cars and the change of lifestyle, more and more people buy cars instead of walking; Coupled with the popularity of air conditioning, these are releasing a lot of hot air into the atmosphere.

Urban population, high-rise buildings and dense roads. Concrete and asphalt pavements make solar radiation heat up quickly and dissipate heat slowly, and the heat island effect is becoming more and more obvious. The temperature of the city is rising gradually, and more and more "stove" cities are emerging. This is also a realistic example of the rapid change and warming of the earth's environment caused by uncontrolled human activities.
