Dynamics of Nonactive Parts of Convective Clouds
Publisher: American Meteorological Society
Abstract: A model of the dynamically inactive parts of cumulus cloud (i.e., void of bulk, organized vertical drafts) is proposed. It is assumed that such parts of clouds consist of coarse filaments of saturated, droplet-containing ...
Entrainment and Mixing in Clouds: The Paluch Mixing Diagram Revisited
Publisher: American Meteorological Society
Abstract: The applicability of the Paluch mixing diagram to studies dealing with cumulus entrainment is reexamined. Theoretical considerations are illustrated with the Paluch method applied to numerically simulated entrainment into ...
Modeling of Subgrid-Scale Mixing in Large-Eddy Simulation of Shallow Convection
Publisher: American Meteorological Society
Abstract: This paper discusses an extension of the approach proposed previously to represent the delay of cloud water evaporation and buoyancy reversal due to the cloud?environment mixing in bulk microphysics large-eddy simulation ...
Droplet Activation and Mixing in Large-Eddy Simulation of a Shallow Cumulus Field
Publisher: American Meteorological Society
Abstract: his paper presents the application of a double-moment bulk warm-rain microphysics scheme to the simulation of a field of shallow convective clouds based on Barbados Oceanographic and Meteorological Experiment (BOMEX) ...
Optical Properties of Shallow Convective Clouds Diagnosed from a Bulk-Microphysics Large-Eddy Simulation
Publisher: American Meteorological Society
Homogeneity of the Subgrid-Scale Turbulent Mixing in Large-Eddy Simulation of Shallow Convection
Publisher: American Meteorological Society
Abstract: his paper presents an approach to locally predict homogeneity of the subgrid-scale turbulent mixing in large-eddy simulation of shallow clouds applying double-moment warm-rain microphysics. The homogeneity of subgrid-scale ...
Impact of Giant Sea Salt Aerosol Particles on Precipitation in Marine Cumuli and Stratocumuli: Lagrangian Cloud Model Simulations
Publisher: American Meteorological Society
Broadening of Cloud Droplet Spectra through Eddy Hopping: Turbulent Entraining Parcel Simulations
Publisher: American Meteorological Society
Abstract: AbstractThis paper discusses the effects of cloud turbulence, turbulent entrainment, and entrained cloud condensation nuclei (CCN) activation on the evolution of the cloud droplet size spectrum. We simulate an ensemble of ...
Radiative Properties of Boundary Layer Clouds: Droplet Effective Radius versus Number Concentration
Publisher: American Meteorological Society
Abstract: The plane-parallel model for the parameterization of clouds in global climate models is examined in order to estimate the effects of the vertical profile of the microphysical parameters on radiative transfer calculations ...
Toward a Numerical Benchmark for Warm Rain Processes
