The climate of Kunming and Guiyang has the characteristics of "four seasons like spring" and "no sunny days in winter" respectively. What kind of weather system is closely related to the above climate characteristics? Kunming quasi-static front

Also known as Yunnan-Guizhou quasi-static front. Located in Yunnan-Guizhou Plateau, it is mainly formed by metamorphic polar continental air mass and southwest airflow blocked by Yunnan-Guizhou Plateau topography. Clouds are low and thin, and it is easy to form rainy weather. The "three sunny days" in Guizhou Plateau are related to the quasi-static front station in Kunming. Appears in winter. The front area is mostly located between Kunming and Guiyang, with a slightly northwest-southeast trend.

Yunnan-Guizhou Plateau is the intersection of two kinds of monsoons, roughly bounded by east longitude 104 degrees, with subtropical monsoon area in the east, warm in winter and hot in summer, and distinct four seasons. The west belongs to the tropical monsoon region, with obvious dry and wet seasons. In summer, influenced by the southeast monsoon and southwest monsoon, the precipitation on the plateau is relatively rich, generally around 1000 mm, and in winter, the cold air from the north is blocked by mountains and Yunnan-Guizhou Plateau, and its power is weak. Between Kunming and Guiyang, it meets the southwest airflow from the south side of the Qinghai-Tibet Plateau, forming a static front in Kunming. Guiyang, located to the east of the static front, is overcast, rainy, cold and humid under the control of the front, and there is a saying that there is no sunny day in winter for half a year. Kunming is located on the west side of the static front, on the warm air side, and the weather is sunny and warm. Kunming is a famous "Spring City" in China. Because of its high terrain and not very hot in summer, it is very pleasant all the year round.
