Abstract: A dynamical model, in conjunction with a microphysical model designed to predict evolution of cloud droplet spectra, is employed to perform two-dimensional simulations of a small nonprecipitating cumulus cloud in the ...

Abstract: Recent observations have shown that even in adiabatic cloud cores, the cloud droplet size distributions are broader than what is expected if all droplets were exposed to the same supersaturation. This suggests the existence ...

Abstract: he purpose of this paper is to quantify the influence of turbulence in collision statistics by separately studying the impacts of computational domain sizes, eddy dissipation rates (EDRs), and droplet sizes and eventually ...

Abstract: eep convection is one of various complex processes driving the evolution of tropical cyclones (TCs). The scales associated with deep convection are too small to be resolved by global NWP models. In the deep convection ...

Abstract: The goal of this work is to answer the question of whether nonuniformity in the spatial distribution of sizes and positions of cloud droplets and/or variable vertical velocity in a turbulent medium can contribute to the ...

Abstract: new system that resolves the stratosphere was implemented for operational medium-range weather forecasts at the Canadian Meteorological Centre. The model lid was raised from 10 to 0.1 hPa, parameterization schemes for ...

Abstract: model evaluation approach is proposed in which weather and climate prediction models are analyzed along a Pacific Ocean cross section, from the stratocumulus regions off the coast of California, across the shallow convection ...
