RISThermodynamic Properties of Mesoscale Convective Systems Observed during BAMEX
Publisher: American Meteorological Society
Abstract: Dropsonde observations from the Bow Echo and Mesoscale Convective Vortex Experiment (BAMEX) are used to document the spatiotemporal variability of temperature, moisture, and wind within mesoscale convective systems (MCSs). ...
The 4 June 1999 Derecho Event: A Particularly Difficult Challenge for Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: Warm season convective system rainfall forecasts remain a particularly difficult forecast challenge. For these events, it is possible that ensemble forecasts would provide helpful information unavailable in a single ...
Idealized Mesoscale Convective System Structure and Propagation Using Convective Parameterization
Publisher: American Meteorological Society
Abstract: The development and propagation of mesoscale convective systems (MCSs) was examined within the Weather Research and Forecasting (WRF) model using the Kain?Fritsch (KF) cumulus parameterization scheme and a modified version ...
Verification of Convection-Allowing WRF Model Forecasts of the Planetary Boundary Layer Using Sounding Observations
Publisher: American Meteorological Society
Abstract: his study evaluates forecasts of thermodynamic variables from five convection-allowing configurations of the Weather Research and Forecasting Model (WRF) with the Advanced Research core (WRF-ARW). The forecasts vary only ...

Forecasting Tornado Pathlengths Using a Three-Dimensional Object Identification Algorithm Applied to Convection-Allowing Forecasts
Publisher: American Meteorological Society
Abstract: three-dimensional (in space and time) object identification algorithm is applied to high-resolution forecasts of hourly maximum updraft helicity (UH)?a diagnostic that identifies simulated rotating storms?with the goal of ...
Tornado Pathlength Forecasts from 2010 to 2011 Using Ensemble Updraft Helicity
Publisher: American Meteorological Society
Abstract: xamining forecasts from the Storm Scale Ensemble Forecast (SSEF) system run by the Center for Analysis and Prediction of Storms for the 2010 NOAA/Hazardous Weather Testbed Spring Forecasting Experiment, recent research ...
Synthetic Satellite Imagery for Real-Time High-Resolution Model Evaluation
Publisher: American Meteorological Society
Abstract: utput from a real-time high-resolution numerical model is used to generate synthetic infrared satellite imagery. It is shown that this imagery helps to characterize model-simulated large-scale precursors to the formation ...
Evaluation of a Probabilistic Forecasting Methodology for Severe Convective Weather in the 2014 Hazardous Weather Testbed
Publisher: American Meteorological Society
Abstract: proposed new method for hazard identification and prediction was evaluated with forecasters in the National Oceanic and Atmospheric Administration Hazardous Weather Testbed during 2014. This method combines hazard-following ...
