摘要
在分析和研究纳木措湖三维动力循环系统数学模型在六个观测站点处淡水的浓度和湖水盐度分布数值模拟实验的过程中,阐述各个观测点处淡水浓度和湖水盐度分布情况并分析形成这种分布格局的原因。模拟试验结果显示:柯氏力在没有湖水分层作用的结合下,对淡水浓度和盐度分布的影响小,但是与湖水分层结合之后,它对淡水浓度和盐度分布起着至关重要的作用。同时湖底的地形对水流的运动起着举足轻重的作用。湖水分层在没有柯氏力的作用下,湖中心特别是湖心表面的淡水浓度和水流的运动却比柯氏力的作用下更高、更活跃。
This article mainly studies the river water concentration and the salinity at the six different stations in Namtso lake by the simulation experiments of three dimensional circulation model. The results showed that the affects of Coriolis force are very small on the distribution of river water concentration and the salinity under the non-stratification. However, the Coriolis force combination with the stratification plays the crucial role in distribution of river water concentration and the salinity and t the bottom terrain of the lake is also very important to it. Additionally in the interior of the lake the river water concentration is much higher and the water movement is much more active in the stratification without the Coriolis force than with the Coriolis force, espeeially on the lake surface.
