| 摘 要： | 应用山两62个气象站1961—2008年春季降水资料,同期NCEP/NCAR月平均再分析资料,用合成分析等方法探讨了山西春季典型干湿年份水汽输送特征差异。研究发现：春季典型干旱年,青藏高原南侧副热带偏西风及其在进入我国东部长江以南地区转向的西南风水汽输送减弱,高原北侧西风带水汽输送亦减弱,而西太平洋副高北侧西风水汽输送显著加强,西侧偏南风水汽输送减弱,使江南西南风向华北的水汽输送显著减少,山西偏北风水汽输送加大出现春旱;同时我国东部长江流域及向北到黄河流域、我国东部沿海水汽通量辐散加强,而华南及沿海水汽通量辐合加强;春季典型湿润年则相反。春季典型干旱年山西西风水汽通量减少和北风水汽通量增加量级相当,典型湿润年山西南风水汽通量增加明显大于西风水汽通量的增加。 |

| Abstract: | Based on the 62 meteorological stations' precipitation data of spring in Shanxi Province from 1961 to 2008,and the contemporaneous NCEP/NCAR monthly mean reanalysis data,the different characteristics of water vapor transport between the typical drought and wet years of spring in Shanxi are analyzed by using composite analysis methods.The research shows that in the typical drought years of spring, the water vapor transport of the subtropical west wind over the south side of the Tibetan Plateau(TP) and that o... |
| Keywords: | typical drought/wet years of spring water vapor transport difference |
