The horizontal nonhomogeneity of the background wind and pressure fields influences the term of the inertial force in the motion equation and the wind speed at the upper boundary of the PBL.

背景风压场的水平非均匀影响了界层运中的性力界层的上界风速。

It is emphasized that the inertial force is unevadable and not to be ignored in Newtonian mechanics.

摘要论述了在牛顿力学中，性力无法避免，也不可忽视。
