What is the reason why Nanjing is particularly hot?

Nanjing is particularly hot because it is located in the southwest of Jiangsu Province in East China, along the Jingjiang River in the lower reaches of the Yangtze River. The main reason for its high temperature is that Nanjing is dominated by low mountains and gentle hills (it can also be said that it is surrounded by mountains), which has a certain blocking effect on the summer monsoon. At the same time, close to the subtropical high center, downdraft and summer dry weather are more obvious.

Nanjing has a humid climate in the north subtropical zone, with four distinct seasons and abundant rainfall. Annual average rainfall 1 17 days, average rainfall 1 106.5mm, relative humidity 76%, frost-free period 237 days. The rainy season is from late June to early July every year. The annual average temperature is 15.4℃, and the annual extreme temperature is the highest 39.7℃ and the lowest-13. 1℃.

Nanjing enters spring in April 1, summer in June 8 and autumn in September 18. Winter is about 165438+ 10/2. Nanjing is short in spring and autumn, long in winter and long in summer, and the temperature difference between winter and summer is significant. Due to the change of atmospheric circulation and the continuous afforestation in Nanjing, the summer heat in Nanjing is much lower than that in other cities, so the name "stove" was removed.
