摘　　要：利用浙江省小流域强风暴监视预警区域的2005～2008年11月FY2静止气象卫星云图红外分裂窗逐时TBB数字资料、影响台风个例资料及中尺度自动气象站1h降水量资料，对红外分裂窗TBB时间变化、按时间归一化处理。TBB与降水量的对应关系、TBB与各量级降水量的累积频率分布等进行处理与分析，得出台风降水的红外分裂窗TBB定量估计指标。通过2007年影响浙江省小流域范围的超强台风“圣帕”影响实例降水的验算，取得较好效果。该指标的得出为利用FY2红外分裂窗TBB数字资料进行台风降水估计与定量分析提供一定的预报依据。Using the infrared wavelength split window numeral data of FY2 satellite from 2005 to July of 2008, the data of influence typhoon and the hourly rainfall of meso-scale station over Zhejiang Province of drainage area, the relationships between TBB and the corresponding station＇s precipitation ,TBB and the cumulative frequency of every grade of rainfall were analyzed after unitary TBB according to time. From the analysis＇ s quantitative indices of infrared wavelength split window TBB about typhonic rainfall were found. The indices gained better effect according to the checking computations on the super typhoon of Sepat,which affected Zhejiang Province of drainage area in August of 2007 .The indices offer a base of forecast about the rainfall of typhoon mad quantitative analysis of FY2 infrared wavelength solit window TBB.
