RISAdvanced Two-Moment Bulk Microphysics for Global Models. Part I: Off-Line Tests and Comparison with Other Schemes
Publisher: American Meteorological Society
Abstract: rognostic precipitation is added to a cloud microphysical scheme for global climate models. Results indicate very similar performance to other commonly used mesoscale schemes in an offline driver for idealized warm rain ...
Parameterization of Cloud Microphysics Based on the Prediction of Bulk Ice Particle Properties. Part III: Introduction of Multiple Free Categories
Publisher: American Meteorological Society
Abstract: he predicted particle properties (P3) scheme introduced in Part I of this series represents all ice hydrometeors using a single ?free? category, in which the bulk properties evolve smoothly through changes in the prognostic ...
A New Approach for Obtaining Advection Profiles: Application to the SHEBA Column
Publisher: American Meteorological Society
Abstract: Time-averaged vertically integrated 3D advections are inferred from heat and moisture budgets obtained from observations at the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment for April, May, June, and ...
Intercomparison of Bulk Cloud Microphysics Schemes in Mesoscale Simulations of Springtime Arctic Mixed-Phase Stratiform Clouds
Publisher: American Meteorological Society
Abstract: A persistent, weakly forced, horizontally extensive mixed-phase boundary layer cloud observed on 4?5 May 1998 during the Surface Heat Budget of the Arctic Ocean (SHEBA)/First International Satellite Cloud Climatology Project ...
Mesoscale Modeling of Springtime Arctic Mixed-Phase Stratiform Clouds Using a New Two-Moment Bulk Microphysics Scheme
Publisher: American Meteorological Society
Abstract: A new two-moment bulk microphysics scheme is implemented into the polar version of the fifth-generation Pennsylvania State University?NCAR Mesoscale Model (MM5) to simulate arctic mixed-phase boundary layer stratiform ...
A New Two-Moment Bulk Stratiform Cloud Microphysics Scheme in the Community Atmosphere Model, Version 3 (CAM3). Part II: Single-Column and Global Results
Publisher: American Meteorological Society
Abstract: The global performance of a new two-moment cloud microphysics scheme for a general circulation model (GCM) is presented and evaluated relative to observations. The scheme produces reasonable representations of cloud particle ...
Impact of Cloud Microphysics on the Development of Trailing Stratiform Precipitation in a Simulated Squall Line: Comparison of One- and Two-Moment Schemes
