Abstract:The seasonally evolutive main modes of North China precipitation and their influence factors are analyzed based on precipitation data from 120 stations in North China,NCEP/NCAR reanalysis data,and Kaplan extended SST data(Kaplan et al.,1998).The results show that there are two main seasonally evolutive modes in North China precipitation,with summer rainfall of the first mode above normal in the central,northern areas and below normal in the southern areas,with that of the second mode less in the northern ar...
Keywords:North China  precipitation  seasonal evolution  main mode  influence factor
