Comparison of Eulerian bin and Lagrangian particle-based microphysics in simulations of nonprecipitating cumulus
Publisher: American Meteorological Society
Abstract: A single nonprecipitating cumulus congestus setup is applied to compare droplet spectra grown by the diffusion of water vapor in Eulerian bin and particle-based Lagrangian microphysics schemes. Bin microphysics represent ...
Numerical Experiments on the Dynamics of the Cloud–Environment Interface: Small Cumulus in a Shear-Free Environment
Publisher: American Meteorological Society
Abstract: We report herein high resolution two-dimensional numerical experiments on the dynamics of the mixing between the environment and a small cumulus cloud in the absence of shear. The current paper extends the work of Klaassen ...
Impact of Explicit Atmosphere–Ocean Coupling on MJO-Like Coherent Structures in Idealized Aquaplanet Simulations
Publisher: American Meteorological Society
Abstract: This paper discusses the impact of the atmosphere?ocean coupling on the large-scale organization of tropical convection simulated by an idealized global model applying the Cloud-Resolving Convection Parameterization (CRCP; ...
Coupling Cloud Processes with the Large-Scale Dynamics Using the Cloud-Resolving Convection Parameterization (CRCP)
Publisher: American Meteorological Society
Abstract: A formal approach is presented to couple small-scale processes associated with atmospheric moist convection with the large-scale dynamics. The approach involves applying a two-dimensional cloud-resolving model in each ...
Extracting Microphysical Impacts in Large-Eddy Simulations of Shallow Convection
Publisher: American Meteorological Society
Abstract: simple methodology is proposed to extract impacts of cloud microphysics on macrophysical cloud-field properties in large-eddy simulations of shallow convection. These impacts are typically difficult to assess because of ...
Untangling Microphysical Impacts on Deep Convection Applying a Novel Modeling Methodology
Publisher: American Meteorological Society
Abstract: icrophysical piggybacking applied previously in shallow convection simulations is employed to highlight microphysical impacts on deep convection. The main idea is to apply two sets of thermodynamic variables, one coupled ...
Representation of Turbulent Mixing and Buoyancy Reversal in Bulk Cloud Models
Publisher: American Meteorological Society
Abstract: This paper discusses the representation of subgrid-scale turbulent mixing in bulk models of warm (ice free) clouds, which assume instantaneous adjustment to grid-scale saturation. This is a reasonable assumption for ...
Impact of Cloud Microphysics on Convective–Radiative Quasi Equilibrium Revealed by Cloud-Resolving Convection Parameterization
Publisher: American Meteorological Society
Abstract: This paper investigates how cloud microphysics impact global convective?radiative quasi equilibrium on a constant-SST aquaplanet. A novel approach, the cloud-resolving convection parameterization (CRCP), also known as ...
Cloud Microphysics and the Tropical Climate: Cloud-Resolving Model Perspective
Publisher: American Meteorological Society
Abstract: This paper discusses the role cloud microphysics play in the tropical climate. It is argued that this problem can best be studied within the context of a cloud-resolving model because of complicated interactions among cloud ...
