There is a saying that there is no sunny day for three days in Guizhou. Is it because it rains all the year round?

It's raining, especially in spring and autumn, and rainy weather will appear every one or two days.

Why does Guizhou have such climate characteristics? I. Geographical Environment Guizhou is located on the eastern slope of Yunnan-Guizhou Plateau, which is a hilly and mountainous area with a high west and a low east, with an average elevation of about 1000 meters. This kind of terrain seems to put a ladder on the ground. The cold air flow will accelerate when it comes down from the top, and the warm air flow will be lifted from the bottom, which is prone to rainy weather. Secondly, Guizhou is also a place where cold and warm air often meet. In summer, the warm air flow in the south is very strong, which almost controls the whole territory of Guizhou. When the heating flow has just invaded, short-term thunderstorm weather often occurs due to terrain uplift. In spring and autumn, the cold air force in the north strengthened and gradually expanded to the south. A cold air accelerated into Guizhou along the east side of the Qinghai-Tibet Plateau and met the retreating warm air. Because cold air and warm air are evenly matched, continuous rainy weather often occurs. Winter is the most vigorous period of cold air development, and the forces of cold air often control most areas of Guizhou Province. At this time, although the cold air is strong, the warm air lurking in the Indian Ocean is still "sneak attack" from time to time, which often forms a stalemate in Guizhou, leading to rain and snow.

It can be seen that it is rainy all year round in Guizhou, so there has been a saying that there is no sunny day since ancient times.
