On the Eddy Diffusion near the Earth-surface

[摘要] In this paper we consider a sort of eddy diffusion which may be expressed by the following differential equation:- where τ is time, a, b and m are constants depending on wind velocity, and the vertical distribution of wind velocity and temperature. Considering that the diffusion does not occur through the earth surface, we obtain solutions for a instantaneous point source and a continuous point source. These solutions show good agreement with experimental results throughout the whole range (100-2000m.) of all experiments.Values of constants will be reported in another paper.
