摘　　要：By Using the P-σ five-layer primitive equation model,three sets of numerical experiments are performed with normal zonal mean SST(the control case),the positive SST anomalies in the Kuroshio current and east-of-Japan Ocean(the midlatitude western Pacific),and positive SST anomalies over both the midlatitude and the equatorial western Pacific.The experimental results show that the positive SST anomalies over the midlatitude western Pacific have great influence on the Asian summer monsoon:the Indian monsoon is weak- ened and the East Asian monsoon is intensified.This happens just reverse to the effects of positive SST anomalies over the equatorial westero Pacific on the Asian summer monsoon.Further,the influence mechanism of the SST anomalies over the midlatitude westcrn Pacific on the Asian summer monsoon is discussed.By Using the P-σ five-layer primitive equation model,three sets of numerical experiments are performed with normal zonal mean SST(the control case),the positive SST anomalies in the Kuroshio current and east-of-Japan Ocean(the midlatitude western Pacific),and positive SST anomalies over both the midlatitude and the equatorial western Pacific.The experimental results show that the positive SST anomalies over the midlatitude western Pacific have great influence on the Asian summer monsoon:the Indian monsoon is weak- ened and the East Asian monsoon is intensified.This happens just reverse to the effects of positive SST anomalies over the equatorial westero Pacific on the Asian summer monsoon.Further,the influence mechanism of the SST anomalies over the midlatitude westcrn Pacific on the Asian summer monsoon is discussed.
