y use of the eddy exchange coefficient K expressed by the quadratic function in Ekman layer which is close to observation, and under the condition of circle pressure field, the wind velocity in the planetary boundary layer (PBL) is obtained.

• 采用与实测较接近的二次函数来表达Ekman层中的湍流粘性系数K，在圆形气压场条件下，求得了山地上空边界层中的风速，进而求得散度、涡度和垂直速度等场变量随高度的分布。
