摘要
用西北地区夏季 ( 6、7、8月 )共 1 9个站降水量观测资料以及NCEP/NCAR 1 95 8～ 1 997年再分析全球月平均网格点前期 (春季 )资料 ,选取西北地区周边范围内夏季干、湿年的前期春季各个物理量场进行相关统计分析 ,结果表明前期春季影响西北地区夏季干、湿的相关区域环流特征和水汽特征有显著差异。
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.
