摘要
对影响广西造成重大灾害的 0 1 0 3号台风“榴莲”进行了综合分析。结果表明 ,强大的正涡度和辐合上升运动区 ,对流层中低层的位势不稳定 ,西风急流和偏东急流的存在和维持 ,两个水汽源地的较强水汽输送等是广西台风大暴雨或特大暴雨产生的必要条件。 0 1 0 3号台风始终沿着大气总能量高能轴线方向移动。大暴雨中心主要分布在台风中心的高能舌顶和不稳定能量舌尖附近区域内 。
The third typhoon ″Durian″ (0103) causing disaster in Guangxi is synthetically analyzed.The results show that the favorable synoptic situation and dynamical struture are indispensable conditions for producing typhoon heavy rain in Guangxi,such as the strong positive vorticity and convergence ascending motion,the convective instability in middle lower troposphere,the west/east wind jets and the strong vapor transfer. The typhoon ″Durian″ always moved along the high energy axis,the heavy rain core lay near the tip of high energy and unsteadiness tongue,and is consistent with the center of positive vorticity.
