Abstract: The factor that contribute to the development of the sharp edge along the poleward boundary of the jet-stream cirrus are examined in three cast studies, using wind field and thermodynamic information from the FGGE dataset ...

Abstract: Two methods designed to parameterize mesoscale ascent in a three-dimensional numerical cloud model via near-surface momentum and heat fluxes are presented and compared to the commonly used technique of an initial perturbation ...

Abstract: During the 2005 NOAA Hazardous Weather Testbed Spring Experiment two different high-resolution configurations of the Weather Research and Forecasting-Advanced Research WRF (WRF-ARW) model were used to produce 30-h forecasts ...
