Abstract: The study was carried out using the Hybrid Coordinate Ocean Model. Both climatological and 10year (1990-1999) simulating results were used. According to the climatological results, the heat transport from Kuroshio to the East China Sea is maximum in winter, and minimum in summer. The transport to the South China Sea is always positive except in summer. The annual mean of heat transport to the East China Sea and South China sea is 1.67×1014 W and 1.5×1014 W. The salt transport changing trend is similar to the heat. According to the wavelet analysis of 1990-1999 simulating results, the transport to the East China Sea has a period of 4 to 7 years, and is negatively correlated with the nino 3.4 index. While the South China Sea transport’s period is 3 to 4 years, and also shows certain correlation with EL Nino.
