Using wind velocity profile law determinate the aerodynamic roughness length of wheats different growth periods: the average roughness of shooting period, is 6.

It is different from traditional concept that the concept dynamic roughness includes influence of model error, truncation error, observation error and so on.

Aerodynamic roughness length is a important feature to easement soil resistance to wind erosion.
