摘要
在笛卡尔坐标下，运用流体水动力学的方法，并在前人观测资料的基础上建立了一个三维水动力数值模式，并对日本琵琶湖风生流进行了数值模拟。结果表明，在5m/s的东南风、西南风、东北风作用下，湖的北端均有气旋式环流出现，在5m/s西北风作用下，湖的北端有反气旋式环流出现。在各种方向风速驱动下，中、低层流场或形成与表层一致的环流型，或呈现明显的垂直切变。
On the basis of former works, a three dimensional numerical model ofthe lake hydrodynamics was designed to simulate the wind - driven current in thisstudy to address the pollutants diffosion, sediment transport, and recentlyworsening water quality of Lake Biwa, Japan. The study results show, the forcingaction of uniform 5m/s SE, SW, NE winds cause an anticlockwise circulation inthe north of the North Basin, but a clockwise circulation in the case of 5m/s NWwind. But the Gyres, currents opposite to those at the surface layer are formed atthe middle and lower layers.
