摘　　要：利用多年的观测资料 ,研究了西太平洋副热带高压对热带海温异常的响应及其相互作用过程。着重研究冬、夏季西太平洋副高对同期及前期不同海域 (特别是赤道东、西太平洋以及印度洋海域 )海温异常的响应 ;用SVD方法分析了夏季副热带高压与前冬、前春及同期各月全球海温的最佳耦合模态。在对比研究西太平洋副热带高压异常时其垂直环流变化的基础上 ,进而研究海气相互作用对副热带高压影响的物理过程。Observational data are used to study the response of subtropical high over the western Pacific on the SST anomalies The correlation of subtropical high strength and SST at various sea areas, lagged and simultaneous, has been calculated Moreover, by using SVD method, the best coupling models between the subtropical high over the western Pacific in summer and the SST in the preceding seasons are studied The longitudinal vertical cells associated with subtropical high are analyzed to investigate the air-sea interactions A specificly vertical circulation related to the subtropical high anomalies is found, which closely links the vertical flow influenced by the SST anomaly in the tropical eastern Pacific
