| 摘 要： | 本文利用二阶矩湍流模式着重讨论了有地形条件下Ekman螺旋的特征，结果表明，在北半球一定的环境地转风场结构下，斜坡Ekman螺旋可以变为反时针旋转。另外，还研究了地形对稳定边界层二阶矩湍流量的结构和垂直分布的影响。

| Abstract: | The characters of the Ekman spirals over a slopped terrain have been discussed by using the second–order model. The results show that under a certain condition of environmental geostrophic wind field, the Ekman spirals will change into counter clock–wise ones in the northern hemisphere. In addition, effects of the terrain on the structure and the vertical distribution of the turbulent second–order in the stable boundary layer have been discussed. |
