Abstract: A conventional anemometer used in the atmosphere or in a wind tunnel measures velocities projected on a plane independently of their directions in the plane. The relation between the frequency distribution of those velocities ...

Abstract: Some elements of the statistical theory of turbulence are briefly reviewed from the viewpoint of their application to micrometeorology.Several relations concerning turbulent diffusion in a field of homogeneous and isotropic ...

Abstract: The dispersion of smoke puffs has been used as a method of measuring turbulent diffusion in the atmosphere. Some of the basic equations of turbulent diffusion as applied to the dispersion of small-scale smoke puff and are ...

Abstract: Turbulent diffusion from an infinite line source in a homogeneous, stationary, non-isotropic turbulent flow is studied. Spatial mean-concentration distributions are determined as functions of the statistical characteristics ...
