| 摘 要： | 利用NCEP/NCAR的在分析资料,分析了1948～2004年期间澳大利亚（以下简称澳高）的年变化和日变化及其对南海夏季风的影响。结果显示在澳高强弱年这种影响有着不同的结果：在年际变化中,澳高与南海夏季风的相关性在澳高弱年明显大于强澳高年;而日变化中,澳高与南海夏季风的相关性在澳高弱年为正,澳高强年则为负。进一步研究表明,造成这些现象的原因大致可以归为：强弱澳高年,越赤道气流的通道变换;西太平洋副热带高压（以下简称副高）的位置偏向;马斯可林高压（以下简称马高）的作用的叠加效应.这些作用对于南海夏季风的重要组成部分：越赤道气流产生了重要影响,从而影响了南海夏季风的强度。

| Abstract: | The interannual variation and daily variation of Australian high effect on the South China Sea summer monsoon for 1948-2004 are analyzed, in the context of NCEP/NCAR reanalysis data. Results show that when the Australian high becomes strong, The significant fact of the correlation relationship between the Australian high intensity and summer monsoon in South China Sea affecting; on the daily variation scale, the anticorrelation relationship between the Australian high intensity and summer monsoon in South China Sea affecting. The influence mechanism of Australia high, Mascarene high, subtropical high over western Pacific and cross-equatorial flow have been preliminary analyzed. |
