| Summary: | In order to study the rules of precipitation change in Nanchang City under thebackground of global warming, based on the precipitation data of Nanchang Station from 1960 to2018, this paper analyzes the change trend, periodic characteristics and abrupt change ofprecipitation by the Mann-Kendall test and wavelet analysis, and discusses the correlation betweenannual precipitation and some global climate indexes. The results show that: The annualprecipitation and the precipitation in the flood season are on the fluctuant rise;It is unsurethat whether there is an abrupt change on annual precipitation and precipitation in the floodseason; The annual precipitation and the precipitation in the flood season have an oscillatingperiod of 28 a, and there is a significant linear relationship between annual precipitation andAntarctic oscillation index. |
