Abstract:The drought has the characteristics of high frequency,long duration and wide range.The precipitation anomaly percentage,Z index and SPI standardized precipitation index are used to analyze the drought characteristics of Chaoyang.The results show that the drought characteristics with the Z index and with the SPI standardized percipitation indes are basically the same,which can reflect the local condition.The natural disasters are discovered to be frequent from 1969 to 2018,and severe drought cases are mainly in 1980,1981,and 1982,which is consistent with the local reality.
