This paper presents a theoretical derivation of the mass and heat fluxes across air-water interfaces. These fluxes are obtained by considering both the advective and dispersive transport processes of water vapor and heat from a water surface with limited down-wind size. Two turbulent diffusion partial differential equations for water vapor and heat transport are coupled through boundary conditions at the water surface. Analytical solutions for the distribution of specific humidity and temperature are obtained in terms of Laplace transform equation from which the fluxes are derived. Results are presented in dimensionless graphical forms covering essentially all practical ranges of meteorological conditions and various sizes of water body. They should facilitate the computations of mass and heat fluxes. Comparison with several empirical formulae indicates that each of them is a special case of the present formulation.
