人工增雨影响区自然降水量的一种估计方法

A Method of Estimating Natural Precipitation on Areas Affected by Artificial Precipitation

在分析各种效果评价方法基础上，作者提出一种估算人工增雨影响区（或作业区）自然降水的方法。该方法不对自然降水的时空分布作平稳性的假设，而是通过分析作业期自然降水特征，事先确定一些判据，从长序列历史样本中获取供比较的样本。该方法可用于人工增雨效果评价。

Based on analysis of varied effect assessment methods, a method of estimating natural precipitation in areas affected by artificial precipitation was suggested. As a matter of fact, the method does not provide an assumption to the spatial and temporal distribution of the natural precipitation at the station, however, through analysis of the feature of natural precipitation during the operation, based on the given criterion, some camparable samples were made. The method can be applied to the assessment of artificial precipitation effect.
