On the basis of the data of the trade wind field in the Pacific Ocean (1950-1972) it is shown that the Kuroshio meander and the El Nino event are not separate phenomena but related with the same air-sea system. It is found from analysis of the data that the cyclonic curl of the tropical wind stress is highly correlated with the anticyclonic curl of the subtropical wind stress. When the intertropical convergence zone (ITCZ) migrates towards the equator from its mean location and reaches its climax, both the cyclonic and anticyclonic curls of trade wind stress reach their maximums while the El Nino is prevailing. When the ITCZ runs rapidly northward against the equator or reaches an extreme point, both the cyclonic and anticyclonic curls of trade wind stress decrease sharply and then the Kuroshio meander occurs.
