本文用垂直方向均分五层，水平网格距离为1km的压缩σ坐标系下的三维数值模型，计算了太湖典型风场SE，NW，SW风生流．分析了太湖湖流及由各层流场平均得到的整层平均流态在这三种典型风场作用下随时间的演变特征；探讨了风应力、水面倾斜压强梯度力、湖底摩擦力三者对湖流垂直结构的影响，初步揭示了太湖湖流垂直结构形成的机理．
In this paper, the three-dimensional numerical model under the compression σ coordinate system with five vertical layers and a horizontal grid distance of 1 km is used to calculate the wind flow of SE, NW and SW in the typical Taihu Lake wind farm. The evolution characteristics of the average flow pattern of the whole layer and the average flow pattern of the whole layer obtained from the flow fields in the Taihu Lake during the period of the three typical wind fields are analyzed. The influences of the wind stress, the gradient pressure on the water surface and the friction on the bottom of the lake On the vertical structure of the lake, revealing the mechanism of the vertical structure of the Taihu Lake.
