摘要
利用1951-2005年NCEP/NCAR再分析资料及华南地区6月份降水资料,统计分析了与华南降水异常相关的西太平洋副热带高压变异、垂直运动及水汽输送等特征。结果表明:华南地区6月份降水异常与南海区域西太平洋副热带高压脊线位置、中心强度等存在非常紧密的联系。
Based on the NCEP/NCAR monthly mean reanalysis data and the observed rainfall data over South China in June from 1951 to 2005,the variations of western Pacific subtropical high(WPSH),vertical motion and the water vapor transport,which are related to the precipitation anomaly in the South China,are analyzed statistically.The main results show that the rainfall over South China in June has very good consistency with the location and intensity of WPSH over the South China Sea.
