| Abstract: | Using the monthly gridded precipitation data in China,the NOAA extended reconstruction sea surface temperature(SST) data,and the NCEP/NCAR reanalysis data,the authors investigate the impact of the ENSO on the interannual variability of late spring-early summer rainfall in Yunnan Province and the relevant physical mechanism.The analysis of composite and correlation study reveal a strong negative correlation between the rainfall anomaly in Yunnan Province and the Nin~o index.An El Nin~o(La Nin~a) event is con... |
