Abstract:
It is found by calculation that good correlation existed between summer rainfall in Shandong Province and SST in equatorial eastern Pacific(EEP) and in North Pacific Current(NPC) areas. On the basis of the correlative analysis,the contemporary and antecedent SST anomaly features of rainy and dry summers and the relations with atmospheric circulations were discussed. The contemporary SST departure (rainy summer minus dry summer) is remarkable, and the negative SST anomaly in EEP area prior to those summers is closely related to negative WP_pattern, and the SST anomaly in NPC area is likely to be modulated by the anomaly of atmospheric circulations. The experiments using SST of Feb. —Apr. in high correlative areas and SSTA of Mar. in EEP area and of July in NPC area show that SST is of great reference value for long-term forecast of summer rainfall in Shandong Province.
