| 摘 要： | 研究了0515号登陆台风“卡努（Khanun）”对江苏暴雨过程的影响．结果表明，此暴雨过程属主要由台风本身的气旋性涡旋所造成的区域性暴雨，位于台风移向的右前方．通过对物理量场诊断分析发现，暴雨强度的趋势与落区基本上能从水汽通量相对散度上反映出来，水汽通量相对散度越大，暴雨越强；暴雨区位于垂直上升运动区．

| Abstract: | The heavy rain in Jiangsu induced by the landing of typhoon 0515 is analyzed. Chiefly it is created by its cyclonic vortex. It located at the right-front side of its moving direction. By diagnostic analysis with physical quantity it is found that the intensity tendency and dropping area of rainfall is clear from the relative divergence of moisture flux. The more the relative divergence of moisture flux, the more the intensity of rainfall. The rainfall is located in the area perpendicular to the rising area. |
