Four big stove cities

The four stoves are Chongqing, Wuhan, Nanchang and Changsha.

With the advent of the industrialization era, environmental pollution is becoming more and more serious. The temperature of the earth is rising year by year. Some time ago, the cold spring that left everyone helpless just ended, followed by the continuous attack of high temperature weather in various places, and many places even went to hot search. Many cities in China have been plagued by high temperature for a long time, such as Chongqing, Changsha, Wuhan, Xi, Fuzhou, Hangzhou, Nanchang and Nanjing. Among many high-temperature cities, the most famous is China's "Four Fireplaces" city.

As the name implies, the "Four Fireplaces" refer to the four hottest cities in China and the names of the four hottest cities in China in summer, which are generally concentrated in the Yangtze River basin in southern China and the Huanghuai area in northern China. When it comes to China's "Four Fireplaces", where do you think of first? Chongqing? Wuhan? Changsha? Indeed, the traditional "four stoves" refer to Nanchang, Chongqing, Wuhan and Changsha.

Brief introduction of four furnaces

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.

The four hottest stoves in China.

Four stoves refer to the four hottest cities in China, but they are not real stoves, they are figurative and exaggerated. It is also 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.

At that time, Chongqing, Wuhan, Nanchang, Changsha and other places in the upper, middle and lower reaches of the Yangtze River Basin were hot in summer, so they were called "four furnaces". With the change of climate and the migration of weather stations, the list of cities is also changing. The four stoves in New China are Wuhan, Nanjing, Chongqing and Nanchang.

The analysis and research of the new four stoves and "hot cities" released on 20 10, the factors considered include heat index, high temperature days, continuous high temperature days, average maximum and minimum temperature in summer, etc.

Scientifically, the hot degree of a city is measured by the number of days with high temperature above 35℃ and the combination of extreme high temperature value and relative humidity. The days with the highest temperature above 35℃ in a year are more than 20 days, and there have been high temperature weather above 40℃. Everyone calls such a city a "stove".

Four stoves were first put forward in the Republic of China, that is, "Chongqing, Changsha, Wuhan and Nanchang" in the Yangtze River basin, mainly because of the hot summer. We know that all physical and geographical factors are constantly changing, that is to say, the climate in different places is also constantly changing. There are both overall changes here. For example, from 1973 to 20 18 in China, the average temperature in summer fluctuates, rises and changes locally, that is, the climate changes in different cities are also different.

Four new stove cities in China.

202 1 The new four stoves are Chongqing, Fuzhou, Hangzhou and Nanchang respectively.

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.

1, Chongqing, also known as Shancheng, is a provincial administrative region, municipality directly under the Central Government, national central city and megacity in People's Republic of China (PRC), one of the important central cities in China, the economic center in the upper reaches of the Yangtze River, an important modern manufacturing base in the country and a comprehensive transportation hub in southwest China. With the approval of the State Council,

2. Fuzhou, referred to as Rongcheng for short, is one of the central cities in the economic zone on the west side of the Taiwan Strait. It is a riverside and coastal ecological garden city approved by the State Council and the capital of Fujian Province.

3. Hangzhou, referred to as "Hangzhou", was called Lin 'an and Qiantang in ancient times. It is a prefecture-level city under the jurisdiction of Zhejiang Province and the capital, sub-provincial city and core city of Hangzhou metropolitan area.

4. Nanchang, referred to as "Hong" or "Chang", was called Zhang Yu and Hongdu in ancient times. It is a prefecture-level city, provincial capital and core city of Poyang Lake urban agglomeration under the jurisdiction of Jiangxi Province, and an important central city in the middle reaches of the Yangtze River in China approved by the State Council.

China's three major stoves

The three stoves in China refer to Nanjing, Wuhan and Chongqing.

1. Nanjing has a humid climate in the north subtropical zone, with an annual average temperature of 15.4℃, an annual extreme temperature of 39.7℃, a minimum temperature of-13. 1℃, and an annual average precipitation of1106mm.

2. Wuhan belongs to subtropical monsoon humid climate zone, with the highest average temperature of 29.3℃ in July and 135 days in summer. There are about 60 days in spring and autumn.

3. Chongqing has a subtropical humid monsoon climate, with an annual average temperature of 16~ 18℃, an average temperature of 26~29℃ in the hottest month, and an average temperature of 4~8℃ in Leng Yue.

Extended data:

1, Chongqing, Wuhan, Nanjing and Changsha, four cities in the Yangtze River valley in the south of China, are called "four furnaces" because of the hot summer climate and the long duration of high temperature and hot summer weather.

2. Fuzhou, Chongqing, Changsha, Nanchang, Hangzhou, Shanghai and Nanjing in the latitude area of the southern Yangtze River are hot in summer and densely populated in provincial capitals, and are known as the "seven furnaces".

3. Jiuzao refers to nine cities in the Yangtze River Basin. The temperature from high to low is Fuzhou, Chongqing, Changsha, Nanchang, Hangzhou, Shanghai, Nanjing, Wuhan and Hefei.

The high temperature in the north is different from that in the south. The high temperature in the north appears in June and July every year, while the high temperature in the south appears in July and August. There are two main areas prone to high temperature in northern China, namely Turpan Basin in Xinjiang, North China Plain and Huanghuai area.

What are the four stoves in the textbook?

The four stoves refer to Chongqing, Wuhan, Nanchang and Changsha.

1, Chongqing

No matter which version of the "four stoves", Chongqing seems to have always been "famous on the list". From 198 1 to 20 10, the number of hot days in summer in Chongqing ranks first in 10 cities, with 28.5 days. Among them, the average days of continuous high temperature above 35℃ are 1 1 day, and the average days above 38℃ are 6.5 days, ranking first.

2. Changsha

Changsha has a special geographical position. The east-west Nanling Mountains straddle Hunan, Guangdong and Guangxi. Its existence has an important influence on the climate in Hunan. The southerly wind prevailing in summer has the effect of burning wind when crossing Nanling mountains, which has a strengthening effect on the hot and high temperature in Hunan in summer. Coupled with the acceleration of urbanization, dense urban buildings and increased automobile exhaust emissions, Changsha has stored more heat, leading to an increase in temperature.

3. Wuhan

Wuhan can be called "the first generation of furnace leaders". There are many rivers and lakes here, a lot of water vapor evaporates, and the whole city is shrouded in clouds of hot air. On the one hand, it slows down the radiation speed of geothermal energy into the air, on the other hand, it makes it difficult for the human body surface to dissipate heat, just like washing a sauna, sweating and sultry. 1one day in 934, Wuhan recorded a temperature of 4 1.3℃, which won the title of "Furnace Chief" for Jiangcheng.

4. Nanchang

The temperature rises in summer, and Nanchang will have an extreme climate of continuous high temperature, sultry, windless and humid from the beginning of July to the end of August every year, which is extremely unbearable. At the hottest time in summer every year, the indoor temperature can reach 33-35 degrees at midnight at 12, and it will not drop until after 3 am.
