The purpose of this paper is to make clear the several statistical properties of turbulence in the natural wind near the ground. Making use of the similarity hypotheses of locally isotropic turbulence, the author builds up a structural model of the turbulent flow field of natural wind, in which the dissipation rate of turbulence energy is considered to depend upon both the distance z from the ground surface and the mean wind velocity U. Thus the properties of the smallest turbulon in wind,

On the other hand, the scale of effective largest turbulon in horizontal directions is considered to depend upon the averaging-time (time duration of observation) T both in the Eulerian and Lagrangian meaning.
