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 ...

Abstract: A 10-level primitive-equation model designed for prediction of circulations within a limited region of the Tropics is described. The model is initialized from wind and temperature information. During the course of the ...

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 ...

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 ...

Abstract: Diabatic experiments with a multi-level primitive equation model were performed using three latent heating parameterization schemes. The concept and method of application of the schemes is discussed, as well as physical ...

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 ...

Abstract: This paper focuses on concrete degradation of hydraulic conveyance components of a hydropower project in Uganda that was commissioned in 2019. During a routine outage inspection in 2021, concrete damage was observed in the ...

Abstract: We have taken an important first step in validating climate models by comparing model and satellite inferred clear sky TOA (top-of-atmosphere) albedos. Model albodos were computed on a 1° ? 1° latitude-longitude grid, ...

Abstract: The water industry worldwide is facing challenges of water and revenue losses. To reduce these losses and improve efficiency of water distribution systems, tools and methods have been developed over the years. This paper ...

Abstract: This paper describes the Earth Radiation Budget Experiment (ERBE) data products being made available to the community. The Science Team used ten validation criteria to judge the acceptability of the data for archival. We ...
