On the turbulent diffusion in the atmosphere.

Abstract

In Part I, a generalized theory of turbulent diffusion is developed by a modification of Inoue's turbulon model theory, and it is shown, with some experimental verifications, that the results in a reasonably assumed case may be applied to certain problems of turbulent diffusion.In Part II, a new governing equation for turbulent diffusion in the atmospheric surfae layer with shear velocity is derived from the viewpoint of mixing-length concept, and the solutions to an important two-dimensional problem are given for large and small dispersion times respectively, with seme experimental verifications.Authors e] p (-e,'A> l G.
