| 摘 要： | 利用NCEP再分析资料结合Micaps资料,对吉林省2010年冬末春初的3次区域性暴雪天气过程的形成机理及落区进行了对比分析。结果表明：3次暴雪过程均发生在有利的大尺度环流背景下,过程1为冷锋型暴雪;过程2为倒槽北上型暴雪;过程3为回流型暴雪。暴雪在吉林省的落区与系统来向、地形作用、水汽与动力大值中心重合区域、湿舌以及θse高能舌等都具有一定关系。

| Abstract: | Based on NCEP reanalysis data and Micaps data,the formation mechanism and falling area of the three regional snow storms which occurred by the end of winter and the beginning of spring in 2010 in Jilin Province was comparatively analyzed.The results showed that the three snow storms were occurred in the favorable large-scale circulation background.Process one was classified as cold front type.Process two was classified as northward inverted trough type.Process three was classified as returnning flow type.Th... |
