Excuse me, where is the lowest temperature in the three southwestern provinces?

The three southwestern provinces include Sichuan, Guizhou and Yunnan, and the lowest temperature should be Guizhou for the following reasons:

Sichuan Basin belongs to subtropical monsoon humid climate, and its main characteristics are: warm winter and hot summer, and long frost-free period. Because there are high mountains in the north, the cold wave is not easy to attack, so the winter is warm, and the average temperature in 65438+ 10 is 4-9℃. The frost-free period of the whole basin is 290-350 days. Summer is long and hot, and it is one of the famous high temperature centers in China.

Kunming, Yunnan is quite dry and warm in winter and spring; The summer half year is mainly influenced by the southwest monsoon, with abundant precipitation, rainy days and high altitude, so the summer temperature is low and the dry and wet seasons are distinct in a year. Under the comprehensive influence of latitude, altitude and atmospheric circulation, the seasonal variation of temperature is small, and the four seasons on the plateau are like spring, so Kunming is called "Spring City".

The altitude of Guizhou is generally around 1000 meters, which is often affected by the cold air in the north in winter and half a year. Cold air comes into contact with warm air, forming the famous quasi-static front in Kunming. Guizhou is often covered by static front for half a year in winter, with many rainy days, which is known as "no sunny days in three days" and cold in winter; Summer is influenced by the southeast monsoon, with more precipitation and higher temperature.

So the temperature in Guizhou is relatively the lowest.
