Precipitation Change Characteristics in Fuxin from 1951 to 2010
Abstract：Based on the monthly and yearly precipitation data of two observational stations from 1951 to 2010 in Fuxin, the climatic change characteristics were analyzed by the trend analysis, the Mexicohat wavelet transform and the Mann-Kendall mutation test method. The results showed that the precipitation in Fuxin in the recent 60 years showed a decreasing tendency of 10.7 mm/10a. The precipitation interan- nual change was obvious, and was prone to drought and waterlogging disasters. The precipitation of sum- mer, autumn and winter showed decline trends except for spring. The yearly precipitation and seasonal precipitation were all apparent oscillation cycle in 12 years and 18 years. There are abrupt changes for precipitation except spring. The abrupt change years for precipitation of summer are in 1967, 1978 and 1986, autumn is in 1996, winter is in 2004.
