Guizhou belongs to low latitude subtropical humid monsoon climate.

Affected by the monsoon, cold and warm air flows frequently meet in Guizhou.

The topography of Guizhou is complicated, which leads to the obvious vertical change of temperature.

The reason why the landlord asked about cloudy days is as follows:

Guizhou is one of the wettest areas in China. The average cloudy day in Guiyang is 238 days, 1 month is 23 days, and September is cloudy 14 days.

In winter, the cold air from the northern mainland has been greatly weakened after going over mountains and mountains. When climbing the rugged Guizhou Plateau, the airflow is very slow. After contact with the warm air originally left in Guizhou, the two sides were evenly matched and deadlocked for a long time, resulting in continuous rain.

In spring, the warm air in the south is strengthened, and the cold air in the north is not to be outdone, which conflicts with each other and the weather is changeable.

In summer, the cold air in the north is withdrawn from the north on a large scale, and the warm and humid airflow from the southern ocean is active in the Guizhou Plateau.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 fluctuates, and the warm and humid air is disturbed by the topographic uplift, which is easy to form clouds and rain. Sometimes cold air from Sichuan meets warm and humid air from the south, which is more likely to form rainy weather.

In autumn, the cold air in the north began to go south, and the warm and humid airflow could not retreat, and the cold and warm air constantly confronted each other, resulting in rainy weather.

In a word, on the rugged ground of Guizhou Plateau, the air is lifted, disturbed, blocked and rubbed, and there are more opportunities for cold and warm air to contact, which are the reasons for the cloudy weather in Guiyang.
