The Discovery and Study of Kunming Quasi-Stationary Front
摘要
Abstract
Kunming Quasi-Stationary Front, also known as Southwest Quasi-Stationary Front, which was found by Chinese meteorologists in 1940s, is a unique frontal system which forms when the cold air outbreaks in East Asia expanding southward, and is obstructed by the terrain in southwest China. Although similar phenomenon has been found in North America, Kunming Quasi-Stationary Front is very unique in terms of formation mechanism, activity patterns and its impact of weather. Under the influence of the Tibetan Plateau, the low-latitude plateau and the Hengduan Mountains, the Kunming Quasi-Stationary Front appears in a north-south direction along the terrain. It has a unique movement pattern of east-west direction and leaping towards west. If it turns into a cold front moving west, turning weather such as cold wave in the southwest part of China is often accompanied. If it remains stable for a long period, it will not only cause disastrous weather such as freezing rain in winter, but also severe convection weather such as thunderstorm, hail and gale in spring. This article begins with the discovery of Kunming Quasi-Stationary Front, followed by a comprehensive review and summary of relevant research progress, and provides some outlooks for future research direction as follows: 1) The deifnition of the Kunming Quasi-Stationary Front has to be clear; 2) The cause of strong frontal inversion and water vapor sources; 3) The climate structure and the circulation characteristics of the Kunming Quasi-Stationary Front; 4) The climate variability and its impact factors of the Kunming Quasi-Stationary Front; 5) The mechanism of the maintenance and the back-and-forth swinging of the Kunming Quasi-Stationary Front; 6) The predictability and the numerical weather forecast capability of the Kunming Quasi-Stationary Front.关键词
