Abstract: Using a regional historical regressive statistical method and based on daily precipitation data from national surface meteorological stations in Liaoning province from 1961 to 1990,the effect of an artificial precipitation enhancement process in Fuxin on August 31,2016,was validated using Tieling as a control area.The results showed that throughout the comprehensive analysis of the data from sounding,radar,and numerical model as well as operating parameters,this artificial precipitation enhancement process meets the requirement of rationality.The increase in absolute rainfall is 20.06 mm,and the increase in relative rainfall rate is 119.43% through the significance testing with the 0.01 significant test level.In comparison with previous studies using the same method in other provinces in China,we find that the choice of statistical variables has great effects on the validation results.
