摘要
采用2002～2006年夏季6～8月热带降水测量（TRMM）卫星3841RT类数据资料，以发生在陕西及周边地区的连阴雨、暴雨和日降水量序列事件为例，通过比较TRMM卫星降水资料与地面气象站观测资料的差异，分析了TRMM卫星对陕西及其周边地区夏季降水过程的探测能力。结果说明TRMM卫星反映的陕西及周边地区夏季降水量值偏小，但探测结果能够大致表现陕西关中和陕南及同纬度周边地区夏季降水量的基本特征，对陕西北部地区夏季降水量的探测能力较差。
Using the summer hourly rainfall data of 3B41RT from TRMM （Tropical Rainfall Measuring Mission） satellite of 2002 -2006, taking continuous rain, storm and daily rainfall series as examples, the TRMM satellite＇s capability for detecting summer rainfall in Shaanxi and its neighborhood regions is analyzed by comparing the rainfall data from TRMM satellite with the data from ground weather stations. The results show that, data from TRMM satellite can indicate the summer rainfall features in the central and southern Shaanxi and its neighborhood regions. But, for northern Shaanxi, its detecting capability is poor.
