Why is it cold in winter in Guizhou and spring in Yunnan?

Because the climate in Guizhou and Yunnan is different.

Guizhou has a warm and humid climate, which belongs to subtropical humid monsoon climate zone. The temperature doesn't change much, it is warm in winter and cool in summer, and the climate is pleasant. The precipitation affected by monsoon is mostly concentrated in summer. The number of cloudy days in all parts of China generally exceeds 150 days, and the relative humidity is above 70% all the year round. Affected by atmospheric circulation and topography, Guizhou has a diverse climate. "One mountain is divided into four seasons, and ten miles are different."

Yunnan province covers many climatic zones, among which subtropical plateau monsoon climate is dominant. Northwest Yunnan has a cold climate, long winter without summer and short spring and autumn. The eastern and central parts of Yunnan belong to temperate climate, with four seasons such as spring and winter when it rains; The south and southwest of Yunnan belong to the low-heat valley area, and some of them enter the tropical area south of the Tropic of Cancer, with long summer without winter and rainy to autumn.

Climate in China:

1, tropical monsoon

Include southern Taiwan Province Province, Leizhou Peninsula, Hainan Island and Xishuangbanna. Annual accumulated temperature >; =8000℃, the average temperature in Leng Yue is not lower than 15℃, the annual extreme minimum temperature is not lower than 5℃ on average for many years, and the extreme minimum temperature is generally not lower than 0℃, and there is no frost all year round.

2. Subtropical monsoon

China, South China and East China all belong to this climate type. The annual accumulated temperature is between 4500-8000℃, and the average temperature in Leng Yue is 0- 15℃, which is a transitional zone between subtropical zone and temperate zone, and the summer temperature is quite high (average temperature >; =25℃ for at least 6 days, that is, 30 days), and the temperature is quite low in winter.

3. Temperate monsoon

North China belongs to this climate type. The annual accumulated temperature is between 3000 and 4500℃. The average temperature in Leng Yue is between-28 and-0℃, and the average temperature in summer is still above 22℃. The temperature over 25℃ is relatively rare and relatively warm and cool.

4. Plateau and mountainous areas

The Qinghai-Tibet Plateau in China belongs to this type of climate. The annual accumulated temperature is lower than 2000℃, the daily average temperature is lower than 10℃, and the hottest temperature is also lower than 5℃ or even lower than 0℃. The daily temperature difference is large and the annual range is small, but the solar radiation is strong and the sunshine is sufficient.

5. Temperate continental nature

The generalized temperate continental climate includes temperate desert climate, temperate grassland climate and sub-frigid coniferous forest climate. In a narrow sense, except for the latter, most of the inland areas of China north of 40 north latitude have temperate continental climate. Precipitation in these areas is scarce, with an annual precipitation of 300-500mm, and the daily temperature range is large, such as Xinjiang in China.

6. Tropical rain forest

Nansha Islands in China belong to this type of climate. It is hot and rainy all year round, with abundant precipitation. The annual average temperature is 28 to 30 degrees, and the annual precipitation is more than 2,800 millimeters. ..
