摘要
根据冯士筰教授于1987年导出的三维质量输运速度的控制方程组出发,在垂直方向上用三次样条函数为基函数作谱展开,水平方向上应用有限差分格式来求解方程组,然后将所提出的计算方法应用于夏季渤海环流,取湍粘性系数随深度变化模式,通过计算可知,潮致余流改变了一般认为夏季渤海环流为一逆时针方向大环流的简单结论,并得到了观测的初步支持。
In the present paper,starting from a set of field equations governing the Lagrangian residual velocity (or the mass-transport velocity),we use cubic spline functions as the basis functions to solve three-dimensional tide-induced Lagrangian residual with abritrarily depth-varing eddy viscosity,and then apply it to the Bohai Sea.The results of calculation are verified by measurements (observations).
