This paper studies the effects of stratification on the turbulent exchange in the surface layer of the atmosphere using the similarity theory and dimensional analysis. Using recently published data, the magnitudes of the empirical coefficient D in the general function of turbulent exchange are calculated. A scheme of transition from forced to free convection showing a rather smooth character is developed. Based on the characteristic length L sub Ri, the author sets up a turbulent exchange model for a diabatic surface layer. Author
