accumulated precipitation meaning in English

累积降水量

It ' s also found that the reanalysis influences the results of 6h accumulated precipitation through changing the non - convective precipitation prediction mainly , while results improved by the nudging assimulation are substantially associated with convective precipitation change
总体上，应用gps可降水量资料调整模式湿度初始场对6h累积降水预报效果的改善优于连续nudging同化对6h累积降水预报效果的改善。
After gps pw data assimulation , the initial humidity field can be reanalyzed while the initial temperature , pressure and wind fields also being modified . although mm5 with the cressman objective analysis predicts the first 6h accumulated precipitation more accurately than 3dvar of gps pw data , vice versa for 6 - 18 h accumulated precipitation
在模式积分的前6小时， cressman客观分析试验对累计降水量预报优于gps可降水量资料三维变分同化试验对累积降水量预报，但在模式积分的6一18小时gps可降水量三维变分同化试验对累计降水的预报却优于cressman客观分析试验。
