Abstract
Similarity problems between prototype and model have been discussed hitherto by many authors, but one of the principal difficulties has seemed to be the lack of a consistent and adequate treatment of conditions for similarity. In the present paper, the relation U∞M/U∞N=(LM/LN)1/3, which has been theoretically obtained by considering not only the similarity of the mean flow patterns but also that of the turbulence structures, is proposed, for practical use, for the modeling criteria for a local wind under the conditions of neglecting molecular viscosity, Coriolis force and variation of hydrostatic pressure, and then the case in which a flow has thermal stratification is discussed.
