The Multi-Radar Multi-Sensor (MRMS) Hydrometeorology Testbed - Hydro (hereafter denoted as HMT-Hydro) experiment is a part of the United States Weather Research Program (USWRP) through the Hydrometeorology Testbed (HMT) that runs from 25 June to 20 July 2018. During the HMT-Hydro experiment, forecasters and hydrologists from the National Weather Service (NWS) will work with National Severe Storms Laboratory (NSSL) research scientists to assess new technology and techniques to improve the prediction and warning of flash flooding. In particular, NWS participants will evaluate new probabilistic hydrologic modeling concepts and output within the Flooded Locations and Simulated Hydrographs (FLASH) system that could help convey the uncertainty of the flash flood threat. NWS participants will also evaluate high resolution precipitation forecasts from the NSSL Warn-on-Forecast (WoF) project and the addition of these forecasts into the FLASH system. Feedback from participants will allow NSSL research scientists to identify how these precipitation forecasts could influence the warning decision making process, including the potential for increased warning lead time. The HMT-Hydro experiment runs in conjunction with the Flash Flood and Intense Rainfall (FFaIR) experiment at the Weather Prediction Center (WPC) to collaborate on the short-term forecasting of flash flooding for both a national and regional scale.

Climate Testbed Awards FY24

WPO’s Climate Testbed partnership with the National Center for Environmental Prediction supports research to improve the operational products at the Climate Prediction Center. We accomplish this by supporting research projects in the collaborative Climate Testbed, which are intended to demonstrate the potential for scientific advances from the external research community to improve operational climate predictions…

Fire Weather FY24 Awards

WPO funds work to advance our understanding of fire weather to improve forecasts of fire behavior and smoke for the public. The projects selected in this competition address the evolution of active fires and smoke, data assimilation of atmospheric and terrestrial conditions, new or improved physics parameterizations, and fire weather forecast system testing and verification.…
