Using long term observation data in the main part of East China Sea Kuroshio, variations of Kuroshio upper layer temperature and salinity, their relationships with surface temperature and precipitation in east China are studied. Results reveal that the Kuroshio upper layer temperature experienced slight rise while salinity decreased in the past 50 years. In winter, Kuroshio upper layer temperature is closely related to the surface temperature in east China, and large area in east China shows positive correlation to the Kuroshio upper layer temperature, which might be related to the mass temperature reduction as a result of the cold air activities in winter. In summer, the increase of the precipitation causes the increase of diluted Yangtze River water into the shelf sea, thereby results in the salinity decrease of Kuroshio in the upper layer.
