| Abstract: | In the context of summer rainfall observations of 19 stations in Northwest China and NCEP/NCAR global monthly mean reanalyzed grid data in spring from 1958 to 1997, correlative statistical analyses are performed on the related parameters in spring in the years of being dry or wet in summer in Northwest China and its nearby regions. Results show that in spring the circulation and moisture features of dry years in the related areas are significantly different from those of wet years. |
