RISSummer Rainfall Forecast Spread in an Ensemble Initialized with Different Soil Moisture Analyses
Publisher: American Meteorological Society
Abstract: The performance of an ensemble forecasting system initialized using varied soil moisture alone has been evaluated for rainfall forecasts of six warm season convective cases. Ten different soil moisture analyses were used ...
On the Impact of WRF Model Vertical Grid Resolution on Midwest Summer Rainfall Forecasts
Publisher: American Meteorological Society
Abstract: Weather Research and Forecast (WRF) model exploratory sensitivity simulations were performed to determine the impact of vertical grid resolution (VGR) on the forecast skill of Midwest summer rainfall. Varying the VGR ...
A Conceptual and Scaling Evaluation of the Surface Wetness Effect on Daytime Moisture Convergence along a Surface Cold Front with Differential Cloud Cover
Publisher: American Meteorological Society
Abstract: A conceptual evaluation and scaling of the potential impact of surface wetness on spring/summer midlatitude daytime surface cold front moisture convergence is presented. First, a simplified expression is derived, evaluating ...
Modified NAM Microphysics for Forecasts of Deep Convective Storms
Publisher: American Meteorological Society
Abstract: AbstractThe Ferrier?Aligo (FA) microphysics scheme has been running operationally in the National Centers for Environmental Prediction (NCEP) North American Mesoscale Forecast System (NAM) since August 2014. It was developed ...
Mesoscale Model Evaluation Testbed (MMET): A Resource for Transitioning NWP Innovations from Research to Operations (R2O)
Publisher: American Meteorological Society
Abstract: wide range of numerical weather prediction (NWP) innovations are under development in the research community that have the potential to positively impact operational models. The Developmental Testbed Center (DTC) helps ...
