The weather in Kunming is November.
The so-called "quasi-static" means seemingly static, not static, but static. The quasi-static front of Kunming is not completely static, but it has the activity law of night (south) advance and day (north) retreat. Why? This is because there is no solar radiation at night, but the cooling of the earth's radiation helps to increase the strength of the cold air mass, so the cold air mass takes the opportunity to secretly retreat to the south. During the day, the solar radiation is strong, and the momentum of the heating mass overwhelms the opponent, which will inevitably recover the lost ground-push the "border" back to the north. Of course, if the cold air mass behind the front has a certain force, or if there is cold air in the north to supplement the "rescue", then the quasi-static front in Kunming will become stronger, and it will often move out of the average position and visit Kunming south, making Kunming rainy all night! Under normal circumstances, the weather brought by the quasi-stationary front in Kunming is not so fierce, but once the stationary front moving south meets the south branch trough full of water vapor, the good play begins: snowflakes fly in the middle and northeast of Yunnan behind the front, and it rains repeatedly in the south of Yunnan before the front! People can't forget two amazing snowfalls in Kunming, "1999.11"and "2000. 1.3 1". That vast expanse of heaven and earth, all white, is a winter gift from Kunming Zhunjingfeng!
The quasi-static front in Kunming is a frequent visitor in Yunnan for half a year in winter and a barometer of the weather in Kunming. As early as 1957, Ping Fan, a senior researcher of Yunnan Meteorological Bureau, devoted great enthusiasm to studying it, put forward the concept of "quasi-static stop in Kunming" for the first time, and summarized some of its activity rules, structural characteristics and forecast indicators. For decades, after unremitting research and exploration by meteorologists, people have a comprehensive understanding of the quasi-static front in Kunming. Especially in recent years, Duan Xu and others have conducted in-depth and detailed research on the three-dimensional airflow structure, genetic mechanism and weather of the quasi-static front in Kunming, which has made people more fully understand the quasi-static front in Kunming, and the forecast accuracy of the quasi-static front and its weather in Kunming has improved year by year!
