Extreme Weather and Climate

Extreme Weather and Climate: In order to produce accurate and timely weather forecasts for extreme weather events (e.g. hurricanes, severe thunderstorms, tornadoes), satellite observations must be combined with prior numerical forecasts from models. The DA group at CIRA develops applications in the area of mesoscale analysis and prediction of severe weather events through the use of ensemble, variational, and hybrid data assimilation.
