A THEORY OF ENTRAINMENT IN CONVECTIVE CURRENTS
Publisher: American Meteorological Society
Abstract: It is held that entrainment is a necessary dynamic consequence of the vertical stretching of an accelerated convective column. On this basis, equations are developed for the rate of entrainment, the vertical divergence and ...
THE VARIATION WITH HEIGHT OF THE VERTICAL FLUX OF HEAT AND MOMENTUM
Publisher: American Meteorological Society
Abstract: Direct measurements have been made of the vertical flux of heat and momentum in the layer from 2 to 12 meters. Eddy velocities were obtained from hot-wire anemometers and light bivanes, mounted at four levels; temperature ...
A NEW APPROACH TO THE PROBLEM OF TURBULENT MIXING
Publisher: American Meteorological Society
Abstract: The principle of dynamic entrainment is applied to the turbulent-mixing problem. With use of the velocity fluctuations characteristic of turbulent flow and the equation of continuity, an expression is derived for the mass ...
POWER SPECTRA OF THE EDDY-VELOCITY COMPONENTS
Publisher: American Meteorological Society
Abstract: Power spectra of the eddy-velocity components have been determined at four levels within the layer from 2 to 12 meters under varying conditions of mean wind speed, trajectory and thermal stability. A filtering technique ...
