强风暴的中尺度结构特征及强风暴与暴雨的大尺度结构差异
THE MESO-SCALE STRUCTURE OF SEVERE STORMS AND THE DIFFERENCE IN LARGE SCALE STRUCTURE WITH HEAVY RAINS
-
摘要: 用滤波方法得到产生强风暴的中尺度天气系统。分析表明:强风暴一般发生在中尺度辐合线、辐合中心及中尺度气旋与反气旋之间,有较强的辐合上升运动,同时还讨论了强风暴与暴雨的大尺度结构差异。Abstract: The mesoscale systems generating severe storms are separated through filtering. This analysis shows that severe storms are preferably occurring near convergence lines and centres,and between mesoscale cyclones and anticyclones, accompanied by strong converging ascending motion. In addition, the difference in large scale structure between severe storms and heavy rains is discussed.
