该文利用地基双频（22.235 GHz（1.35 cm）和35.3 GHz（8 mm））微波辐射计和热带降雨测量卫星微波成像仪（TRMM/TMI）两种被动微波遥感资料分别反演安徽寿县地区云中液态水含量，运用统计回归方法得到该地区云水含量的反演公式，揭示了该地区云中液态水含量存在一个阈值0.4 mm，当云中液态水含量超过这一阈值时，该地区一般就会出现降水。在降水发生之前，水汽和云中液态水含量均会出现一个显著增加的过程，而在降水结束之后则会出现一个显著减少的过程。

Two kinds of passive microwave remote sensing data from a ground-based dual-frequency (22.235GHz (1.35 cm) & 35.3GHz (8 mm)) microwave radiometer and a Tropical Rainfall Measuring Mission Microwave Imager (TRMM/TMI) are used for cloud liquid water amount retrieval in the Shouxian area of Anhui. Based on the statistic regression method, the retrieval formulas for cloud liquid water amount in this area are educed. It shows that there exists a threshold of 0.4 mm for cloud liquid water amount in this area, and when the cloud liquid water amount exceeds this threshold, the precipitation occurs. Before the precipitation, there appears a process of obvious increase in the amount of water vapor and cloud liquid water, and after the precipitation, a process of obvious decreases.
