摘　　要：本文用GMS－4IR云图云顶亮温（TBB）值及其某一TBB值域的象素点值与华东热带气旋暴雨区域进行统计分析，得出华东热带气旋内部TBB≤－54℃的区域基本上是暴雨区域，但不同季节时的TBB值可有所变化。从而为华东热带气旋暴雨数值产品释用研究中确定海上热带气旋暴雨区域提供了参考。In this paper, through statistical analysis of brightness temperature of cloud top (TBB)of GMS-4 IR, the picture element of the numerical domain of TBB and the area that produced torrential rain of tropical cyclone in the east China, we get a result that the region of the TBB≤-54℃ in the inner area of tropical cyclone in the east China is basically the torrential rain area, but the TBB may change in different seasons
