Eddy Diffusivity/Mass Flux and Shallow Cumulus Boundary Layer: An Updraft PDF Multiple Mass Flux Scheme
Publisher: American Meteorological Society
Abstract: n this study, the eddy diffusivity/mass flux (EDMF) approach is used to combine parameterizations of nonprecipitating moist convection and boundary layer turbulence. The novel aspect of this EDMF version is the use of a ...
A Unified Model for Moist Convective Boundary Layers Based on a Stochastic Eddy-Diffusivity/Mass-Flux Parameterization
Publisher: American Meteorological Society
Abstract: single-column model (SCM) is developed for representing moist convective boundary layers. The key component of the SCM is the parameterization of subgrid-scale vertical mixing, which is based on a stochastic eddy-diffusi ...
A Unified Eddy-Diffusivity/Mass-Flux Approach for Modeling Atmospheric Convection
Publisher: American Meteorological Society
Abstract: AbstractA fully unified parameterization of boundary layer and moist convection (shallow and deep) is presented. The new parameterization is based on the stochastic multiplume eddy-diffusivity/mass-flux (EDMF) approach, ...
Implementation of a Stochastic Eddy-Diffusivity/Mass-Flux Parameterization into the Navy Global Environmental Model
Publisher: American Meteorological Society
Abstract: unified boundary layer and shallow convection parameterization based on a stochastic eddy-diffusivity/mass-flux (EDMF) approach is implemented and tested in the Navy Global Environmental Model (NAVGEM). The primary goals ...
On the Factors Controlling the Development of Shallow Convection in Eddy-Diffusivity/Mass-Flux Models
Publisher: American Meteorological Society
Abstract: This study addresses key aspects of shallow moist convection, as simulated by a multiplume eddy-diffusivity/mass-flux (EDMF) model. Two factors suggested in the literature to be essential for the development of convective ...
The Strong Impact of Weak Horizontal Convergence on Continental Shallow Convection
Publisher: American Meteorological Society
Abstract: Idealized large-eddy simulation (LES) is a basic tool for studying three-dimensional turbulence in the planetary boundary layer. LES is capable of providing benchmark solutions for parameterization development efforts. ...
A Global View on the Wind Sea and Swell Climate and Variability from ERA-40
Publisher: American Meteorological Society
Abstract: In this paper a detailed global climatology of wind-sea and swell parameters, based on the 45-yr European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA-40) wave reanalysis is presented. The spatial pattern of ...
