| 摘 要： | 利用华南暴雨试验期间稠密的雨量资料对热带测雨卫星（TRMM）微波成像仪（TMI）频率为85．5GHz（波长0．35cm）的测雨能力进行了考察。通过TMI－85．5GHz亮温分布和一小时雨量分布的对比发现，对流性降水的强雨量中心与TMI－85．5GHz亮温的低值区有很的对应关系，雨带分布和低亮温分布的位置及形状都很相似，雨强的大小和亮温的关系也相当密切：雨强越大，亮温值越低。亮温数值和雨强（指每小时雨量，下同）的相关统计进一步表明：雨强的大小与亮温呈明显的负相关，特别是当雨强达到或超达7mm/h时的相关程度非常显著，从而确认了TMI－85．5GHz的微波遥感对对流性强降水有较好的测雨能力。
