中文摘要:

      利用摄动方法,解析求解了含有地形的非线性斜压行星边界层的风场及其顶部的垂直速度。将所得结果与其它工作比较,说明了斜压性、地形和非线性平流对边界层中风场分布和顶部垂直速度的影响。

英文摘要:

      By the perturbation method, the wind structure and vertical motion within the non-linear baroclinic PBL above topography are determined. These results are disscussed by comparision with other works. It is demonstrated that the contributions of baroclinity, topography and nonlinear effects to the wind profile of the PBL are all of definite importance.
