Abstract:

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.
