Analysis on Characteristics of Precipitation Change from 1957 to 2015 in Weishan County
Abstract: The climatic changes of annual precipitation, annual, seasonal, monthly and abrupt change of precipitation in Weishan County from 1957 to 2015 were calculated by using linear regression analysis, cumulative anomaly method and Morlet wavelet analysis. The results show that the annual, intertemporal, seasonal and monthly precipitation of different seasons shows a decreasing trend in different degrees. From 1960s to 1980s, the precipitation was decreasing, and the precipitation was decreasing from 1990s to 2010s. The annual precipitation decreased with the trend of linear trend of -13.0 mm/10a. The annual precipitation changed in 1969, 1974, 2003 and 2009. The cycle of annual precipitation was mainly in 8 and 32.
