建立滇中地区大-暴雨与低涡等天气系统预报模式

Establish Forecast Model of Central Yunnan Heavy Rain-Rainstorm Winth Weather System of Low Pressure Vortex

滇中地区地处低续度高原 ,紧邻青藏高压 ,故影响滇中地区的低涡的形成、维持、发展、消失 ,都受高压的直接作用。早在很久以前 ,人们就根据各地的天气特点 ,对低涡进行了不同角度的研究。就目前而言 ,对低涡的研究仍以个例分析较多 ,缺乏较全面的综合分析 ,特别是对影响滇中的低涡研究很少 ,因此本题就对影响滇中的低涡进行天气和动力学分析 ,提出了一些影响滇中低涡的自身特点和带来的天气 。

Central Yunnan Which lies in the low latitudes high-lands is close to the Qinghai-Xizang Plateau. So the formation, maintainance, development as well as disappearance of its low pressure vortex are all influenced directly by high pressure. Long before, by the weather characteristics of different places, people made some different researches on low pressure vortex. As for the present, researches on low pressure vortex are concentrated on some individual analyses but lack overall analyses, especially with fewer researches on the influence of Central Yunnan low pressure vortex. With the weather and dynamic analyses done to the influence of Central Yunnan low pressure vortex, this article puts forward some characteristics which influence Central Yunnan low pressure and some possible weather changes in order to provide some direct and quantitative bases for weather forecast.
