RISModification of the Thermodynamic Structure of the Lower Troposphere by the Evaporation of Precipitation: A GEWEX Cloud System Study
Publisher: American Meteorological Society
Abstract: The importance of subcloud evaporation to the thermodynamics and movement of cold fronts is investigated through inclusion of an explicit cloud scheme within a 30-km resolution limited-area model. Two cases are examined: ...
Midlatitude Frontal Clouds: GCM-Scale Modeling Implications
Publisher: American Meteorological Society
Abstract: The importance of subgrid-scale processes for the simulation of midlatitude frontal clouds by global models is investigated. The case chosen is a frontal cloud associated with a cool change crossing the southern Australian ...
Impacts of Land Surface Model Complexity on a Regional Simulation of a Tropical Synoptic Event
Publisher: American Meteorological Society
Abstract: A multimode Chameleon Surface Model (CHASM) with different levels of complexity in parameterizing surface energy balance is coupled to a limited-area model (DARLAM) to investigate the impacts of complexity in land surface ...
Limited-Area Model Sensitivity to the Complexity of Representation of the Land Surface Energy Balance
Publisher: American Meteorological Society
Abstract: By coupling a multimode land surface scheme with a regional climate model, three scientific issues are addressed in this paper: (i) the regional model's sensitivity to the different levels of complexity presented by the ...
Simulations of a Cold Front by Cloud-Resolving, Limited-Area, and Large-Scale Models, and a Model Evaluation Using In Situ and Satellite Observations
Publisher: American Meteorological Society
Abstract: The Global Energy and Water Cycle Experiment has identified the poor representation of clouds in atmospheric general circulation models as one of the major impediments for the use of these models in reliably predicting ...
Hydrological Processes in Regional Climate Model Simulations of the Central United States Flood of June–July 1993
Publisher: American Meteorological Society
Abstract: Thirteen regional climate model (RCM) simulations of June?July 1993 were compared with each other and observations. Water vapor conservation and precipitation characteristics in each RCM were examined for a 10° ? 10° ...
