[Method] Based on the data of annual precipitation in Anyang and Nanyang from 1953 to 2009, the changes of precipitation in Anyang and Nanyang were compared by means of mathematical statistics, regression analysis and wavelet analysis. [Result] In recent 57 years, annual precipitation in Anyang and Nanyang showed decrease trend, especially Anyang with obvious decrease trend; from seasonal variation, average precipitation in spring and winter went up in Anyang and went down in Nanyang, while average precipitation in summer and autumn reduced in two cities; from periodic variation, when the time scale of precipitation in Anyang was 12-15 years, there was a catastrophe point in 1970, and Nanyang had two catastrophe points in 1965 and 1997 when the time scale of precipitation was 15 years and 4 catastrophe points in 1968, 1978, 1987 and 1999 when time scale was 7-10 years. [Conclusion] The study could provide theoretical foundation for the forecast of local climate changes.展开更多
