A Fully Unified Eddy-Diffusivity/Mass-Flux (EDMF) Parameterization in the U.S. Navy Global Weather Prediction Model
Abstract
Funds are provided to conduct research to develop and evaluate a new fully unified boundary layer and deep convection parameterization based on the multiple-plume Eddy-Diffusivity/Mass-Flux (EDMF) approach. This is a turbulence and convection parameterization that can be considered fully unified, in the sense that it is able to represent convective processes from boundary layer to deep moist convection with one single parameterization. The goal is to develop a scheme that can be implemented into the NAVGEM and NEPTUNE models. The EDMF parameterization will be extended to deep convection, allowing for a full unification of the parameterization of all turbulent and convective processes that occur in the Earth???s atmosphere including deep moist convection. A necessary step to extend EDMF to precipitating deep convection conditions is to couple the MF component to a cloud microphysics scheme. The physics of downdrafts and cold pools associated with deep convection will also be included.
