摘要
利用我国武汉IGS跟踪站的观测数据及地面降雨资料对武汉地区的一次短时的强降雨过程进行了监视分析，结果表明：在降雨发生前，大气中的水汽含量会出现持续增加的过程，并且在强降雨发生前2～3h大气水汽含量会急剧上升；当降雨发生后水汽含量逐渐降低，大气水汽含量的增减与降水的发生与停止呈现出一致性。
Rainstorm that happened in Wuhan is monitored with GPS data which was obtained from IGS station Wuhn .The results show that the value of atmosphere water vapor increased continuously before the rainfall happened es-pecially before two or three hours and decreased gradually after the rainfall hap-pened .The rainfall has direct relationship with the value of atmosphere water vapor .
