摘    要:选取1952-2005年北太平洋月平均海表温度(SST)资料,经过奇异值分解分析表明:6月份日界线附近西风漂流区的海温集中了北太平洋海温场的主要信息,西风漂流区与赤道冷水区的海温存在遥相关震荡,并且在6月份达到全年的最高值,11月份其振幅出现次高值。6月西风漂流区的海温(SST)可视为来年盛夏(7-8月)西太平洋副热带高压的强弱变化的信号:当6月份西风漂流区的海温(SST)偏低,则来年盛夏西太平洋副热带高压偏强;反之,则来年盛夏西太平洋副热带高压偏弱。

关 键 词:西风漂流区  赤道冷水区  奇异值分解  副热带高压  遥相关

Abstract:Based on singular value decomposition analysis of 54 years ( 1952-2005 ) monthly mean sea surface temperature (SST) over North Pacific Ocean, the paper indicates the SST of west wind drift area around dateline at June represents main information of SST of North Pacific Ocean; there is SST teleconnection disturbance between West Wind Drift Area and Equatorial Cold Water Area; it reaches the maximum at June and sub-maximum at November. The further analyses show the SST around West Wind Drift Area at June can be signaled the strength of Subtropical high of West Pacific in the next Midsummer: SST of West Wind Drift Area is lower (higher) at June, the Subtropical high of West Pacific for the next Midsummer becomes stronger (weaker) .
Keywords:west wind drift area  equatorial cold water area  singular value decomposition  subtropical high  teleconnection
