Forecasters to test experimental lightning data
NOAA National Weather Service (NWS) forecasters will test how lightning data impacts the warning process during convective events in the NOAA Hazardous Weather Testbed from July 21-August 29. The project is a collaboration between NSSL and Earth Networks, Inc., a private weather company.
Earth Networks has indicated the potential for its continental scale total lightning network (ENTLN) data and associated “Dangerous Thunderstorm Alerts” (DTAs) to increase forecaster situational awareness and lead times. Prior limited studies have shown the use of total lightning detections and associated derivative products could have positive impacts on the warning process.
During the tests, Earth Networks lightning data and its DTA products will be implemented into NWS operational software (AWIPS2) in the NOAA Hazardous Weather Testbed. Forecasters will complete a series of weather-warning scenarios in displaced real time, ranging from marginally severe to high-impact tornadic events for a variety of geographic locations.
These tests will evaluate the feasibility of using this data in warning operations, as well as the impact on warnings issued by NWS forecasters. The final outcome of this project is to make recommendations on possible product improvements, and determine whether Earth Networks products should become part of the operational product suites available to NWS offices nationally.
