Turbulent Motion in the Atmosphere. (Third Paper)

[摘要] Up to the present, there appeared two theories essentially different from each other concerning the mechanism of eddy diffusion. One is the mechanism of momentum conservation by L. Prandtl and the other that of vorticity conservation by G. I. Taylor. In the present report, as a successive one of our previous researches on the same problem, is adopted the form of eddy distribution;η=η0(1±σz)2.In this case, also are perceived some superior points of Taylor's theory to Prandtl's, but the both are not still satisfactory enough to explain the distribution of wind velocity and the angle of inclination with height, so far as it concerns Dobson's data, when we adopt the condition of the coincidence of eddy stress with surface wind in direction at z=0 assumed by Taylor and others.
