The definition of aerodynamic parameters in the wheat fields and their analysis

In this paper, using the model of wind profile of Monin-Obukhov in the near surface layer, the zero-plane displacement d; the roughness parameter z₀; friction velocity u and aerodynamic resistance factors γ_av and γ_am are calculated. The characteristics of d, z₀, u_*, γ_av and γ_am, and their variations with wind velocity and stability are analyzed and discussed.
