THE RATIO OF THE EXCHANGE COEFFICIENTS FOR HEAT AND MOMENTUM IN A HOMOGENEOUS THERMALLY STRATIFIED ATMOSPHERE

Abstract

A hypothesis concerning the ratio of the exchange coefficients for heat and momentum is formulated. From the basic assumptions of the Monin-Obukhov similarity theory and the theory of free convection, it is shown that the ratio of the coefficients is a two-part function of the nondimensional logarithmic wind shear and the gradient Richardson number. Experimental data tend to corroborate the theoretical values derived in this study within the limits of experimental error.
