| 摘 要： | 热带气旋碧利斯和格美,在起源地、路径和结构上有一定的相似,但登陆后降水强度却有明显差异.通过对两个热带气旋登陆后环境场和物理量场的对比分析,得出一些结论.热带气旋登陆后暴雨强度与高空盛行东北气流和南海西南季风加强有关.高低空不同的环流形势导致了这两个热带气旋登陆后华南沿海低层辐合、高层辐散、上升运动、水汽及不稳定度等物理量场的不同,从而造成暴雨强度的不同.

| Abstract: | Tropical cyclones Bilis and Kaemi have similar track and construction but their intensity of rainfall are very different. Their circulation and physical fields are compared and the conclusions show that the rainfall of landing tropical cyclones is associated with the prevailing northeast air flow at upper level and intensified southwest monsoon. The low level convergence, high level divergence, ascending motion, water vapor transport and instability energy for these two tropical cyclones over South China were significantly different under the different patterns, resulting in different rainstorms during the two tropical cyclones. |
