It has been pointed out by analysis of data covered 33 years (from 1951 to 1983) that the effect of the anomalous thermal state of the equatorial Eastern Pacific on the frequency of typhoon over the Western Pacific is obvious. El Nino event in 1982-1983 indicated: by meridional cell, the anomalous SST (sea surface temperature) can affect the interaction between middle and low latitudes circulation, which restricted typhoon activities over the Western Pacific. In other words, when warm water occured in the e...
