摘　　要：首先依据拉格朗日环流理论与黄、东海的环流物理和几何特征建立一个黄、东海环流的动力学统一模型 ,并按其无因次方程的量阶分析获得其零阶和一阶模型方程。最后依此模型方程的数学、物理特征确立了流速分解方案 ,从而形成完整的黄、东海拉格朗日环流数值模型。该课题组已完成较系统地对黄、东海环流的数值研究。该篇论文为系列报道之首篇。This is the first paper in a series where the general circulation in the Yellow Sea and East China Sea is studied numerically in the frame of the Lagrangian circulation theory. In this paper the dynamic model is established according to the physical and geometric features of the Yellow Sea and the East China Sea based on the Lagrangian circulation theory. The zeroth order and first order equations are derived from the above model by scale analysis. Then the current splitting method is proposed to solve the differential equations numerically. Thus the numerical Lagrangian circulation model is established in the Yellow Sea and the East China Sea.
