Abstract: A two-layer model of the marine boundary layer is described. The model is used to simulate both stratocumulus and shallow cumulus clouds in downstream simulations. Over cold sea surfaces, the model predicts a relatively ...

Abstract: A prognostic cloud scheme is described based on Tiedtke's cloud parameterization for large-scale meteorological models, which uses prognostic equations for both mean liquid water content and cloud fraction. The present ...

Abstract: This study focuses on the effects of drizzle in a one-dimensional third-order turbulence closure model of the nocturnal stratus-topped marine boundary layer. When the simulated drizzle rate is relatively small (maximum ...

Abstract: An analysis of the condensation and evaporation processes involved in the classic Sommeria?Deardoff?Mellor turbulence cloud models is presented. A liquid water budget is derived from the diagnostic Gaussian cloud relations. ...

Abstract: Large eddy simulation is used to study top-hat parameterizations of second- and third-order scalar statistics in cumulus and stratocumulus cloud-topped boundary layers (CTBLs). Although the top-hat parameterizations based ...

Abstract: he impact of gravity waves on marine stratocumulus is investigated using a large-eddy simulation model initialized with sounding profiles composited from the Variability of American Monsoon Systems (VAMOS) Ocean?Cloud?At ...

Abstract: he impact of aerosol replenishment in a stratocumulus-topped boundary layer (STBL) on cloud morphology and albedo is examined using a large-eddy simulation (LES) model in conjunction with a prey?predator-type dynamical ...

Abstract: A mean-gradient model of the dry convective boundary layer is developed using a convective mass flux representation of the turbulent fluxes. A top-hat model of thermals is used to represent the average characteristics of ...

Abstract: An updraft and downdraft circulation model based on a mass flux representation of convective fluxes is incorporated into a classic cloud-topped, mixed layer model. The convective mass flux is assumed to be proportional to ...

Abstract: A regional version of a two-layer model is used to simulate marine boundary-layer clouds over an area (20°?42°N and 117°?145°W) of the eastern North Pacific. The large-scale conditions required for the model are provided ...
