摘要

描述了一种三维数值环流模型。该模型基于非线性流体动力学方程，并根据流体静力学和Boussinesq近似进行了修正。对控制方程的数值逼近采用了空间分割格式。利用椭圆流函数形状的简单假设来重建近地面风场。计算的水流与整个湖泊不同位置的观测速度相当吻合。

A mixed finite element/control volume model of wind-driven circulation in lakes

A three-dimensional numerical circulation model is described. The model is based on non-linear hydrodynamic equations, modified according to hydrostatic and Boussinesq approximations. A space-splitting scheme is used for numerical approximations of governing equations. The simple hypothesis on elliptic stream functions shape is utilized to reconstruct the near-surface wind field. The calculated currents correspond reasonably well with observed velocities in different locations lake-wide.
