Abstract: | This paper investigates the influence of Indian Ocean Dipole (IOD) on climatic variations over East Asian monsoon region, based on CAS IAP AGCM-Ⅱduring Equatorial East Pacific Ocean SSTA or not. The results show that the southwest monsoon over East Asian will break out later than normal, the intensity of the summer monsoon over the South China Sea (SCS) is stronger than normal, and more rainfall on Chinese main land is simulated when only IOD forcing exists. With both IOD and Equatorial East Pacific Ocean SSTA forcing, the southwest monsoon will break out much later than normal, the intensity of the SCS summer monsoon also is weaker than normal, and less rainfall in North China is simulated. Therefore, Equatorial East Pacific Ocean SSTA and IOD have a synergic effect. |
