| 摘 要： | 针对2004年7月10~13日,北京地区的一次特大暴雨过程,本文利用处于该时期的地基GPS观测数据,根据地基GPS气象学原理反演出大气可降水量PWV(Precipitable Water Vapor)序列,采用最小二乘曲线拟合的方法,结合实测降水量,研究了PWV序列和RH(Relative Humidity)序列在暴雨过程中所反映出的变化规律。

| Abstract: | From 10th to 13th of July, 2004, Beijing was struck by a big rainstorm, of which the data were obtained by the ground-based GPS equipments. With these data, and according to the principles of GPS meteorology, the authors deducted the PWV(Precipitable Water Vapor)series. Based on least square fitting and the amount of actual precipitation water, they studied how the PWV series and the RH(Relative Humidity)series reflect the variety of the rainstorm. |
