What are the four stoves in China?

The four stoves in China are Chongqing, Wuhan, Nanchang and Nanjing.

First, Chongqing

The heat in Chongqing originates from the topography, and it is a famous high temperature area in midsummer in China. Physical location is the main factor. Because it is located in the low-lying area of Sichuan basin, it is difficult for water vapor to spread out, and the air humidity is high, so it is difficult for hot air to spread around. Secondly, there are factors such as foehn effect, Qinghai-Tibet high pressure and urban heat island effect, which maintain the high temperature in Chongqing.

Second, Wuhan.

There are many rivers and lakes in Wuhan, and a large amount 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 human body surface to dissipate heat, just like taking a sauna, sweating and sultry. At the same time, southerly winds often prevail on the ground in summer, and the weak warm advection brought by southerly winds is not conducive to cooling at night.

Third, Nanchang

Nanchang is surrounded by mountains on three sides, Jinggangshan in the west, Wuyishan in the east and Nanling in the south. The cool subtropical monsoon (southeast wind) is repelled by these mountains. Without the wind, hot air will gather slowly and will not disperse for a long time.

Fourth, Nanjing.

Nanjing is surrounded by mountains, which can block the summer monsoon to some extent. At the same time, close to the subtropical high center, downdraft and summer dry weather are more obvious. At the same time, the urban heat island effect makes the urban area hotter.

Topography of Chongqing:

There are Daba Mountain in the north, Wushan Mountain in the east, Wuling Mountain in the southeast and Dalou Mountain in the south of Chongqing. The elevation of the main urban area of Chongqing is mostly between 168 ~ 400 meters. The highest peak in the city is Yintiaoling, the main peak of Liang Jie on the eastern edge of Wuxi County, with an altitude of 2796.8 meters; The lowest is the Yangtze River in Wushan County, with an altitude of 73. 1 meter. The height difference in Chongqing is 2723.7 meters. The territory of high mountains and deep valleys, ravines. Mountain areas account for 76%, hills account for 22%, and valley flat dams only account for 2%.

Among them, the area below 500 meters above sea level is 3 1.8 thousand square kilometers, accounting for 38.1%of the national territory; 20,900 square kilometers at an altitude of 500-800 meters, accounting for 25.46438+0% of the land area; 16800 square kilometers at an altitude of 800 ~ 1200m, accounting for 20.42% of the national territory; Above sea level1.200m1.280km2, accounting for 15.56% of the national territory.
