The Effect of Slipping Condition On the Ground on the Motion of Air in the Atmosphere

[摘要] The relation between the gradient wind velocity and surface wind velocity has first been studied by Guldberg and Mohn as early as 1876. Since then, G. I. Taylor obtained, by introducing the eddy viscosity of the atmosphere, the equation based on the assumption that the directions of the stress components just agree with those of the wind components. Recently Y. Ishimaru and others touched upon the same problem with different conditions and obtained the resulting relation in the form where _??_ is a constant being determined from the nature of the eddy motion.In this paper, the author discussed the same problem using the surface conditions where r, s are slipping coefficients, η the coefficient of eddy viscosity, and obtained the following relation The results represented by theory were found to agree fairly with those obtained by direct observation at Croydon, Lympne, Calshot, Holyhead, Lindenberg, Naba and Tateno.
