摘要
Abstract
Three evaluation methods for the nonrandomized precipitation enhancement operation effects have been developed based on the regional rainfall control and meteorologiT cal covariable correlation: Dopple ratio analysis evaluation method using regional rainfall ten-dency control for single cloud seeding operation case ;regression analysis evaluation effects on the bases of regional correlation and developing tendency of rainfall;and multiple regression analysis with meteorological and physical covariables. It is shown from the evaluation exam-ples of effects for cloud seeding operation cases carried out in the central region of Henan Province ,that the inferential accuracy of natural rainfall on the cloud seeding operational area could be improved by using appropriate physical covariables as control factors ,then the eval-uational efficiency of efficiency for the nonrandomized cloud seeding operations can be in-creased.关键词
