摘要: 本文利用高空探测站点的逐日、逐月和多年平均资料,研究了不同时间尺度大气中水汽含量的间接推算方法。结果表明,利用统一公式借助地面水汽压推算的累年月平均值,具有较高的可信度,其平均相对误差一般不超过10%,历年月平均推算值要差一些,其相对误差在13—15%之间,而逐日值则较难利用地面湿度资料进行推算,尤其是南方的夏季。

关键词: 大气水汽含量, 估算方法, 中国大陆

Abstract: The total atmospheric water vapor is a neccesary data for not only the quantitative forecast of cloud and rainfall ,but also radiance computation. The distribution of the average total precip-itable water in China has been studied by many scientists. They all used the data from upper-air stations ,and discussed the mean values of years.

Key words: Estimating method, Total at mospheric water vapor, Mainland of China
