Abstract: Nocturnal drainage flows observed over a nearly two-dimensional ridge called Rattlesnake Hills near Richland, Washington are simulated by using a simplified turbulence closure model in which only turbulence kinetic energy ...

Abstract: An improved, second-moment turbulence-closure model and a random particle kernel diffusion model are described and tested with the 1982 ASCOT (Atmospheric Studies in Complex Terrain) data collected in Brush Creek, Colorado. ...

Abstract: A simple mixed-layer model with variable inversion strengths is validated with data. An algorithm is developed to obtain mixed-layer heights by analytically solving a cubic polynomial equation which is derived from, but ...

Abstract: A second-moment turbulence-closure model described in Yamada and Bunker is used to simulate nocturnal drainage flows observed during the 1984 ASCOT field expedition in Brush Creek, Colorado. In order to simulate the observed ...

Abstract: The purpose of this study was to demonstrate the feasibility of operating the three-dimensional atmospheric models HOTMAC (higher-order turbulence model for atmospheric circulation) and RAPTAD (random puff transport and ...

Abstract: A three-dimensional ensemble-mean atmospheric model, with simplified second-moment turbulence closure equations and a statistical treatment for the condensation process, is used to simulate a fair weather marine boundary ...

Abstract: he second phase of the Global Land?Atmosphere Coupling Experiment (GLACE-2) is a multi-institutional numerical modeling experiment focused on quantifying, for boreal summer, the subseasonal (out to two months) forecast ...
