The parameterization of turbulent and convective mixing in global atmospheric models has been a major challenge in weather and climate research for several decades. In particular, different parameterizations are used, and patched together often artificially, for different types of convection: dry or moist, in the boundary layer or in the full troposphere. The Eddy-Diffusivity (ED) approach has been relatively successful in representing the properties of neutral and stable boundary layers and surface layers in general. The Mass-Flux (MF) approach, on the other hand, has been used for the parameterization of shallow and deep moist convection. In this presentation, an approach based on an optimal combination of the ED and MF parameterizations (EDMF) is discussed in detail as a solution for the full unification of the parameterizations of turbulent and convective mixing in atmospheric models. In particular, we will present results from a new multi-plume stochastic EDMF parameterization that fully unifies the representation of convection in weather and climate models: One single parameterization that represents the effects of dry, shallow and deep moist convection in the atmosphere.
