The Spatial-Temporal Structure of 500-hPa Zonal Wind in Summer in the Tibetan Plateau and Its Relationship to the Precipitation in China
青藏高原夏季500hPa纬向风的时空演变特征及其与我国降水的关系

Using the Empirical Orthogonal Function(EOF),correlation and composition analysis,the interannual and interdecadal variability of the 500-hPa zonal wind in summer in the Tibetan Plateau and its relationship to the precipitation in China are examined,based on the monthly NCAR/NCEP reanalysis data and the precipitation data from 160 stations in China.The results of spatial-temporal structure reveal that: in general,500-hPa zonal wind in summer in the Tibetan Plateau shows a decreasing trend since 1950.And the...
