中文摘要: 通过降水过程中空间相邻区域在气象卫星水汽通道的亮温数据相对差来描述水汽相对差，近似为降水量的相对差，使降水量的分布趋势得到了较为细致的体现。利用它对插值算法进行修正，提高点降水量的估算准确度，从而使估算的面降水量更加接近实际面降水量。
中文关键词: 水汽通道，亮温，面降水量
Abstract:The relative difference of vapor TBB in the nearby area reveals the distribution of vapor,it can be treated as the approximation of rainfall's distribution of the area at the same time. With this distribution,the simulation of area rainfall can be modified. The simulating result is quite close to the actual rainfall than that without modified. As a result,the accuracy of the rainfall simulation was improved greatly by this method.
