Four Furnace Cities

The four major furnace cities

The four major furnace cities are Chongqing, Wuhan, Nanchang and Changsha.

With the advent of the industrialization era, environmental pollution is increasingly intensifying. The earth's temperature is rising year by year. The spring cold that left everyone helpless some time ago has just ended, and what follows is the continuous onset of high-temperature weather in various places. Many places have even become hot searches for this. There are many cities in our country that have always been troubled by high temperatures, such as Chongqing, Changsha, Wuhan, Xi'an, Fuzhou, Hangzhou, Nanchang, Nanjing, etc. Among the many high-temperature cities, the most famous are undoubtedly the “Four Furnace” cities in my country.

As the name suggests, the "Four Furnaces" refer to the four cities with the hottest weather in China. They are the names for the four major Chinese cities with the hottest summer weather. They are generally concentrated in the Yangtze River Basin in southern China, and the Huanghuai area in North China. Speaking of my country’s “Four Furnaces”, which one do you think of first? Chongqing? Wuhan? Changsha? This is indeed the impression. The traditional "four furnaces" refer to Nanchang, Chongqing, Wuhan and Changsha.

Introduction to the Four Great Furnaces

The Four Great Furnaces refer to the four cities with the hottest weather in China. They are the names for the four major Chinese cities with the hottest summer weather. Generally Concentrated in the Yangtze River Basin in southern China and the Huanghuai area in northern China. It first started during the Republic of China. At that time, Chongqing, Wuhan, Nanchang and Changsha in the upper, middle and lower reaches of the Yangtze River Basin had hot summers, so they were known as the "Four Furnaces". As climate changes and weather stations move, so do the city lists.

The term "stove" first reflected the public's intuitive feelings, and there has been no clear definition and standard for a long time. After the 21st century, furnace cities began to use heat index, number of high temperature days, number of consecutive high temperature days, average maximum and minimum temperatures in summer as factors for selection.

China's four hottest stoves

The four hottest stoves refer to the four hottest cities in my country. They are not real stoves. They are metaphorical and exaggerated. This is also true. The names of the four major Chinese cities with the hottest summer weather are generally concentrated in the Yangtze River Basin in southern China and the Huanghuai area in northern China.

At that time, Chongqing, Wuhan, Nanchang and Changsha in the upper, middle and lower reaches of the Yangtze River Basin had hot summer climates, so they were said to be known as the "Four Furnaces". With climate change and the relocation of meteorological stations, the city list is also changing. The four major furnaces of New China are Wuhan, Nanjing, Chongqing, and Nanchang.

The New Four Hot Stoves announced in 2010, an analysis and study of "hot cities", consider factors including heat index, number of high temperature days, number of consecutive high temperature days, average maximum and minimum temperatures in summer, etc.

Scientifically, the number of days with high temperatures above 35°C, as well as extreme high temperature values ​​and relative humidity are used to measure the heat of a city. There are more than 20 days with the highest temperature exceeding 35°C in a year. Moreover, there have been high-temperature weather above 40℃, and people call such cities "furnaces".

The Four Great Stoves were first proposed during the Republic of China. They were located in the four cities of "Chongqing, Changsha, Wuhan and Nanchang" located in the Yangtze River Basin, mainly due to the heat in summer. We know that all natural geographical elements are constantly changing, which means that the climate in various places is also constantly changing. There are overall changes. For example, the average summer temperature in my country from 1973 to 2018 has been There is a fluctuating upward trend, and there are also local changes, that is, the climate change conditions in different cities are also different.

China’s New Four Great Furnace Cities

The New Four Great Furnace Cities in 2021 are Chongqing, Fuzhou, Hangzhou and Nanchang.

The Four Great Furnaces refer to the four cities with the hottest weather in China. They are the names given to the four major Chinese cities with the hottest summer weather. They are generally concentrated in the Yangtze River Basin in southern China and the Yellow River in North China. Huaihe area.

China's Three Great Furnaces

China's Three Great Furnaces are Nanjing, Wuhan and Chongqing.

1. Nanjing has a humid northern subtropical climate, with an average annual temperature of 15.4°C, annual extreme temperatures of up to 39.7°C and a minimum of -13.1°C, and an average annual precipitation of 1106 mm.

2. Wuhan belongs to the subtropical monsoon humid climate zone. The average temperature in July is the highest at 29.3°C. Summer lasts for 135 days; spring and autumn are about 60 days each.

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

Extended information:

1. Chongqing, Wuhan, Nanjing, and Changsha in the Yangtze River Basin in southern China are said to have hot summer climates and long-lasting high temperatures and hot weather. "Four Furnaces".

2. Fuzhou, Chongqing, Changsha, Nanchang, Hangzhou, Shanghai, and Nanjing in the latitude area of ​​the Yangtze River in the south have hot summer climates and densely populated provincial capital cities, which are said to be the "seven furnaces."

3. The nine big furnaces generally refer to the nine cities in the Yangtze River Basin. From high to low, they are Fuzhou, Chongqing, Changsha, Nanchang, Hangzhou, Shanghai, Nanjing, Wuhan and Hefei.

4. High temperatures in the north are different from high temperatures in the south in that high temperatures in the north occur in June and July every year, while in the south there are two main areas prone to high temperatures, namely the Xinjiang Turpan Basin and the North China Plain. And the Huanghuai area

What are the four major cities in the textbook

Four. The big stoves refer to the four cities of Chongqing, Wuhan, Nanchang, and Changsha.

1. Chongqing

No matter which version of the "Four Big Stoves", Chongqing seems to always be on the list. From 1981 to 2010, Chongqing ranked first among the 10 cities in the number of high temperature days in summer, with 28.5 days. Among them, the average number of consecutive high temperature days above 35℃ was 11 days, and the average number of days above 38℃ was 6.5 days, both indicators also ranked first.

2. Changsha

Changsha has a special geographical location, with the east-west Nanling Mountains stretching across the border between Hunan and Guangxi. , its existence has an important impact on Hunan's climate. The foehn effect produced by the prevailing southerly wind in summer when crossing the Nanling Mountains has a strengthening effect on Hunan's hot and high temperatures in summer. Coupled with the accelerated urbanization and urban buildings. Factors such as dense urbanization and increased vehicle exhaust emissions have caused more heat to be stored in Changsha's urban area, causing the temperature to rise.

3. Wuhan

Wuhan can be called "the leader of the generation." ". There are many rivers and lakes here, and water vapor evaporates in large quantities. The hot air covers the entire city. On the one hand, it slows down the radiation of heat from the ground to the air. On the other hand, it makes it difficult for the surface of the human body to dissipate heat. It is like a sauna, sweating like pulp, and sweltering. Unbearable. The record of 41.3°C in Wuhan on a certain day in 1934 earned Jiangcheng the title of "King of Furnace"

4. Nanchang

When the temperature rises in summer, Nanchang will continue to suffer. The extreme climate of high temperature, sweltering heat, windlessness, and humidity is extremely unbearable from early July to the end of August every year. During the hottest period of summer, the indoor temperature can reach 33-35 degrees at 12 o'clock in the morning, and the temperature does not drop until after 3 o'clock in the morning. .
