利用超前滞后相关分析研究了西太平洋副热带高压与海表面温度异常的关系。选取各关键海区分析海温与西太副高在不同时段上的超前滞后相关, 结果表明，冬季东太平洋海温与滞后其2—3个月的副高异常达最大正相关，热带印度洋海温异常与冬季同期副高异常的正相关最显著；西太平洋海温在冬春季与同期的副高负相关最显著；北太平洋海温在冬春季滞后副高1—2个月时存在负相关，大西洋暖池区6月与西太副高的同期正相关最大；对南太平洋来说，冬季的西太副高与从前秋到春季的SST都存在最大负相关。海表温度的异常主要解释冬春季的西太副高异常，而对于夏秋季副热带高压，SST的作用比较有限

The authors study the relationship between the Western Pacific Subtropical High (WPSH) and sea-surface temperature (SST) anomaly in each selected key area based on lag correlation analysis. The lag correlation indicates that the eastern Pacific SST in winter correlates with the WPSH anomaly two or three months later to the highest degree; the SST in the tropical Indian Ocean and the WPSH anomaly in the corresponding period significantly correlates with each other in winter; and the SST in the western Pacific in winter and spring negatively correlates to the WPSH anomaly in the corresponding period. In addition, the SST in the northern Pacific in winter and spring negatively correlates with the WPSH anomaly one to two months earlier. The largest positive correlation between the Atlantic Warm Pool and the WPSH anomaly in the corresponding period occurs in June. Regarding to the southern Pacific, the WPSH anomaly in winter negatively correlates with the SST anomaly from last autumn to next spring. To sum up, in winter and spring, SST anomaly is almost fully responsible to the annual variation of the WPSH anomaly, but in summer and autumn, the influence of SST on the WPSH is constrained to a small scale.
