NOAA Hazardous Weather Testbed

Spring Experiment

At the height of the spring severe weather season, the NOAA HWT hosts multiple experiments to evaluate the operational utility of new science, technology and products.

The Spring Experiments are a unique opportunity for researchers and forecasters to work side-by-side to evaluate emerging research concepts and tools and participate in experimental forecast and warning generation exercises. Forecasters have direct access to the latest research developments and scientists gain the knowledge to formulate research strategies that will have practical benefits. This collaborative approach ensures an effective, two-way path between research and operations which ultimately improves NWS forecasts and warnings.

NSSL, the Storm Prediction Center (SPC) and the Norman National Weather Service Forecast Office lead the effort.

Spring Experiments are subdivided into forecast-related activities and warning-related activities.

2015 Forecast Program: May 4–June 5, 2015

Researchers and forecasters investigate the use of convection-allowing model forecasts of the atmosphere to improve predictions of hazardous and convective weather events. Each day during the project they examine and evaluate a variety of model output and create and verify experimental severe weather forecasts. Read more →
