A PDF-Based Formulation of Microphysical Variability in Cumulus Congestus Clouds
Publisher: American Meteorological Society
Abstract: alculating unbiased microphysical process rates over mesoscale model grid volumes necessitates knowledge of the subgrid-scale (SGS) distribution of variables, typically represented as probability distribution functions ...
Simulating the Transition from Drizzling Marine Stratocumulus to Boundary Layer Cumulus with a Mesoscale Model
Publisher: American Meteorological Society
Abstract: A case of coastal California summer season boundary layer cloud has been simulated with the U.S. Navy Coupled Ocean?Atmosphere Mesoscale Prediction System and the results analyzed in the context of consistency with conclusions ...
A PDF-Based Microphysics Parameterization for Shallow Cumulus Clouds
Publisher: American Meteorological Society
Abstract: nbiased calculations of microphysical process rates such as autoconversion and accretion in mesoscale numerical weather prediction models require that subgrid-scale (SGS) variability over the model grid volume be taken ...
A Bulk Parameterization of Giant CCN
Publisher: American Meteorological Society
Abstract: A parameterization for giant cloud condensation nuclei (GCCN), suitable for use in bulk microphysical models, has been developed that uses precise representations of the condensational growth of aerosol particles in the ...
Effects of Sea-Salt Aerosols on Precipitation in Simulations of Shallow Cumulus
Publisher: American Meteorological Society
Abstract: suite of large-eddy simulations with size-resolving microphysical processes was performed in order to assess effects of sea-salt aerosols on precipitation process in trade cumulus. Simulations based on observations from ...
Fidelity of Analytic Drop Size Distributions in Drizzling Stratiform Clouds Based on Large-Eddy Simulations
Publisher: American Meteorological Society
Abstract: Cloud microphysical parameterizations and retrievals rely heavily on knowledge of the shape of drop size distributions (DSDs). Many investigations assume that DSDs in the entire or partial drop size range may be approximated ...
Assessing the Errors of Cloud Liquid Water and Precipitation Flux Retrievals in Marine Stratocumulus Based on Doppler Radar Parameters
Publisher: American Meteorological Society
Abstract: The errors of formulations of cloud retrievals based on radar reflectivity, mean Doppler velocity, and Doppler spectrum width are evaluated under the controlled framework of the Observing System Simulation Experiments ...
Thermodynamic and Aerosol Controls in Southeast Pacific Stratocumulus
Publisher: American Meteorological Society
Abstract: near-large-eddy simulation approach with size-revolving (bin) microphysics is employed to evaluate the relative sensitivity of southeast Pacific marine boundary layer cloud properties to thermodynamic and aerosol parameters. ...
Evaluation of Warm-Rain Microphysical Parameterizations in Mesoscale Simulations of the Cloudy Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: everal warm-rain microphysical parameterizations are evaluated in a regional forecast model setting (using the Naval Research Laboratory?s Coupled Ocean?Atmosphere Mesoscale Prediction System) by evaluating how accurately ...
Large-Eddy Observation of Post-Cold-Frontal Continental Stratocumulus
Publisher: American Meteorological Society
Abstract: More studies on the dynamics of marine stratus and stratocumulus clouds have been performed than comparable studies on continental stratocumulus. Therefore, to increase the number of observations of continental stratocumulus ...
