The NOAA HWT Spring Experiment is a yearly experiment that investigates the use of convection-allowing model forecasts as guidance for the prediction of hazardous convective weather. A variety of model output is examined and evaluated daily, and experimental forecasts are created and verified to test the applicability of cutting-edge tools in a simulated forecasting environment. The variety of model output allows us to explore different types of guidance, including products derived from both ensembles and deterministic forecasts, and to provide focused feedback to model developers. The 2011 Spring Experiment will be held from May 9th through June 10th in the HWT facility at the National Weather Center in Norman. The Experiment is scheduled to run Monday through Friday from ~730am to 5pm. In addition to the traditional focus on severe convection, the 2011 Experiment will also explore use of convection-allowing models to address the challenges of convective initiation and convective heavy rain forecasting. More information about this year's Experiment can be found below in the 2011 Spring Experiment Operations Plan. |
