Multiscale Statistical Properties of a High-Resolution Precipitation Forecast
Publisher: American Meteorological Society
Abstract: Small-scale (less than ?15 km) precipitation variability significantly affects the hydrologic response of a basin and the accurate estimation of water and energy fluxes through coupled land?atmosphere modeling schemes. It ...
Value of Human-Generated Perturbations in Short-Range Ensemble Forecasts of Severe Weather
Publisher: American Meteorological Society
Abstract: During the spring of 2003, the Storm Prediction Center, in partnership with the National Severe Storms Laboratory, conducted an experiment to explore the value of having operational severe weather forecasters involved in ...
Extracting Unique Information from High-Resolution Forecast Models: Monitoring Selected Fields and Phenomena Every Time Step
Publisher: American Meteorological Society
Abstract: A new strategy for generating and presenting model diagnostic fields from convection-allowing forecast models is introduced. The fields are produced by computing temporal-maximum values for selected diagnostics at each ...
Revisiting the 3–4 April 1974 Super Outbreak of Tornadoes
Publisher: American Meteorological Society
Abstract: The Super Outbreak of tornadoes over the central and eastern United States on 3?4 April 1974 remains the most outstanding severe convective weather episode on record in the continental United States. The outbreak far ...
Next-Day Convection-Allowing WRF Model Guidance: A Second Look at 2-km versus 4-km Grid Spacing
Publisher: American Meteorological Society
Abstract: During the 2007 NOAA Hazardous Weather Testbed (HWT) Spring Experiment, the Center for Analysis and Prediction of Storms (CAPS) at the University of Oklahoma produced convection-allowing forecasts from a single deterministic ...
Toward Improved Convection-Allowing Ensembles: Model Physics Sensitivities and Optimizing Probabilistic Guidance with Small Ensemble Membership
Publisher: American Meteorological Society
Abstract: During the 2007 NOAA Hazardous Weather Testbed Spring Experiment, the Center for Analysis and Prediction of Storms (CAPS) at the University of Oklahoma produced a daily 10-member 4-km horizontal resolution ensemble forecast ...
Some Practical Considerations Regarding Horizontal Resolution in the First Generation of Operational Convection-Allowing NWP
Publisher: American Meteorological Society
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 ...
Assessing Advances in the Assimilation of Radar Data and Other Mesoscale Observations within a Collaborative Forecasting–Research Environment
Publisher: American Meteorological Society
Abstract: The impacts of assimilating radar data and other mesoscale observations in real-time, convection-allowing model forecasts were evaluated during the spring seasons of 2008 and 2009 as part of the Hazardous Weather Test Bed ...
Project CRAFT: A Real-Time Delivery System for NEXRAD Level II Data Via the Internet
Publisher: American Meteorological Society
Abstract: The NOAA NWS announced at the annual meeting of the American Meteorological Society in February 2003 its intent to create an Internet-based pseudo-operational system for delivering Weather Surveillance Radar-1988 Doppler ...
