| 摘 要： | 根据抚仙湖的特点,提出了一个二维分层积分数值模式.应用该模式探讨了抚仙湖内波及上、下层流场特征.计算结果表明:在无旋风场作用下,内波在空间上作42.5h周期性旋转;在有旋风场作用下,抚仙湖北部湖区存在转向相反的双层水平环流,并且上层的反时针环流主要是由湖区正旋度附加风场作用而形成的.模拟结果与观测事实吻合较好.

| Abstract: | A numerical integral model of two-dimensional stratification is proposed in accordance with the features of Lake Fuxian. The model is used to study some characteristics of internal waves and epilimnion as well as hypolimnion currents in the lake. Computed results show that the internal waves rotate counterclockwise with a period of 42.5 hours in the case of nonrotational wind, that two layers of horizontal cyclic gyres, which rotate in opposite directions, exist in the northen part of Lake Fuxian in the case of rotational wind, and that the counterclockwise cyclic gyres in-the upper layer of the lake are mainly caused by rotational wind, etc. The simulated results agree well with observed facts. |
