Altay Prefecture artificial precipitation weather modification effect evaluation

Abstract

Effect of artificial precipitation was preliminarily evaluated in Altay Prefecture using daily precipitation data in seven weather stations from 1960 to 2015, and the dataset of surface hourly grid precipitation with the resolution of 0.1 degree in China from 2014 to 2015 provided by China Meteorological Data Service Center. The mean snowfall in winter had increased by 20.80 mm in the prefecture due to artificial snowfall. Furthermore, the percentage of snowfall in winter accounting for annual total precipitation had increased from 15.50% to 22.39%. The mean annual precipitation had increased by 39.47 mm, half of which was due to artificial snowfall, indicating significant effect of artificial snowfall. In addition, the mean rainfall in summer had increased by 16.59 mm in Altay Prefecture due to artificial rainfall with rain increasing rate of 4%, indicating that the effect of artificial snowfall in winter was more significant than artificial rainfall in summer.
