中文摘要: 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 phy
sical fields
are compared and the conclusions show that the rainfall of landing tropical cycl
ones is associated with the prevailing northeast air flow at upper level and i
ntensified southwest monsoon. The low level convergence, high level divergence,
ascending motion, water vapor transport and instability energy for these two tr
opical cyclones over South China were significantly different under the differen
t patterns, resulting in different rainstorms during the two tropical cyclones.
