Assessment of Model Error in Limited-Area Simulations of Shallow Water Test Cases on the C-Grid Plane and Sphere
Publisher: American Meteorological Society
Abstract: suite of limited-area test cases for the solution of the shallow water (SW) equations on the plane and sphere is collected and evaluated using the Model for Prediction Across Scales (MPAS) modeling system. Included are ...
A Study of Cloud Mixing and Evolution Using PDF Methods. Part I: Cloud Front Propagation and Evaporation
Publisher: American Meteorological Society
Abstract: The evolution of mean relative humidity (RH) is studied in an isobaric system of clear and cloudy air mixed by an incompressible velocity field. A constant droplet radius assumption is employed that implies a simple ...
Comparison of Narrow Bipolar Events with Ordinary Lightning as Proxies for the Microwave-Radiometry Ice-Scattering Signature
Publisher: American Meteorological Society
Abstract: The narrow bipolar event (NBE) is a unique lightning discharge that has a short (?10 ?s) overall duration, lacks a prior leader phase, and produces too little light output to be visible by optical lightning detectors on ...
Unified Treatment of Thermodynamic and Optical Variability in a Simple Model of Unresolved Low Clouds
Publisher: American Meteorological Society
Abstract: Comparative studies of global climate models have long shown a marked sensitivity to the parameterization of cloud properties. Early attempts to quantify this sensitivity were hampered by diagnostic schemes that were ...
Another Look at Stochastic Condensation for Subgrid Cloud Modeling: Adiabatic Evolution and Effects
Publisher: American Meteorological Society
Abstract: The theory of stochastic condensation, which models the impact of an ensemble of unresolved supersaturation fluctuations S? on the volume-averaged droplet-size distribution f?(r), is revisited in the modern context of ...
