Causes of rainy, cold and humid weather in Guizhou

Why is there a saying that it will be sunny for three days in Guizhou?

Guizhou Province is one of the wettest areas in China, and also one of the most rainy areas, with more than 200 rainy days in a year. On average, three of the four days are cloudy. Therefore, Guizhou Province is "sunny for three days".

Why are there so many rainy days in Guizhou Province? Let's discuss it from the four seasons.

In winter, the power of cold air from the northern mainland has been greatly weakened after long-distance pulling and crossing mountains and mountains. After climbing the rugged Guizhou Plateau, because both sides are evenly matched, it will produce rainy and continuous weather!

In spring, the warm air in the south has gradually strengthened, and the cold air in the north is not to be outdone. The result of the conflict is that the weather is uncertain, rainy and changeable!

In summer, the cold air in the north spreads to the north on a large scale, and the warm and humid airflow from the southern ocean is active in the Guizhou Plateau. The altitude of Guizhou Plateau is above 1000 meters, and the ground is uneven. Warm and humid air is disturbed by the ground uplift, which is easy to form clouds and cause rainfall. Sometimes cold air from Sichuan meets warm and humid air from the south, which is more likely to form rainy weather or strong thunderstorm weather!

In autumn, the cold air in the north began to go south, and the warm and humid air stream could not retreat. Constant confrontation between cold and wet air currents often leads to rainy weather!

In a word, the rugged ground of Guizhou Plateau, where air rises, stirs, blocks and rubs, has a lot of contact opportunities with cold and warm air, which is the main reason for the continuous rain in Guizhou. Due to the humid climate in most parts of Guizhou, it is very suitable for the growth of trees, with more than 2,000 kinds of trees!
