建立了一个全球大洋变网格环流数值模式,中国近海的分辨率为1/6°.由模式得出了通过南海和东海开边界的体积、热、盐输运的各月和全年平均值,所得结果与已有的基于观测所得的体积输运估计值有良好一致性.结果显示,通过南海加入印尼贯穿流的体积、热、盐输运值为5.3 Sv,0.57 PW和184 Gg·s-1。,约占印尼贯穿流的1/4,表明南海是太平洋到印度洋贯穿流的重要通道之一.东海的黑潮输运值各为25.6 Sv,2.32 PW和894 Gg·s-1。,其中不到1/4通过西表岛与冲绳岛之间的水道.热平衡计算表明,南海从太阳和大气获得净热通量,其值为0.08 PW;而大气则从渤黄东海获得净热通量,其值为0.05 PW.
A global ocean-going gridded circulation numerical model was established with a resolution of 1/6 ° in the offshore China.The monthly and annual mean values of volume, heat and salt transport through the SCS and the East China Sea are obtained from the model , And the results obtained are in good agreement with the existing observations based on volumetric transport.The results show that the volume, heat and salt transport values through the South China Sea into Indonesia through the stream are 5.3 Sv, 0.57 PW and 184 Gg · s -1. , Accounting for about 1/4 of the total through-flow in Indonesia, indicating that the South China Sea is one of the important passages through the Pacific Ocean to the Indian Ocean. The Kuroshio transport values in the East China Sea are 25.6 Sv, 2.32 PW and 894 Gg · s-1, respectively. , Less than a quarter of which pass through the watercourse between Iriomote Island and Okinawa.The thermal balance calculation shows that the South China Sea receives a net heat flux from the sun and the atmosphere at a value of 0.08 PW and the atmosphere receives a net heat flux from the Bohai Sea Amount, which is 0.05 PW.
