The United States experiences over 1,000 tornado’s per year; causing an average of $5 billion in damage, 80 fatalities, and over 1,500 injuries. The most destructive and deadly tornados occur in supercells – rotating thunderstorms with a well-defined circulation called a mesocyclone. Collection and processing of in situ data pertaining to thermodynamic conditions in tornadic supercell thunderstorms is critical to enhancing severe weather forecasting and mitigating the destructive effects of these tornados.
Project Storm leverages the CU Boulder’s proven expertise and extensive capability in nomadic, integrated collection of real-time supercell data using unmanned aircraft systems (UAS) to better predict tornadogenesis and dramatically increase Tornado Warning lead-time. CU Boulder collaborates with an established network of government, academic, and industry partners to improve measurement and collection of supercell data. The CU Boulder Earth Lab works closely with IRISS to process and distribute datasets for improved tornado forecasting techniques.
Goals of Project
- Deployment to verify CONOPS for autonomous, integrated, multi-UAS collection of In Situ Tornadic Supercell data
- Collaboration with NOAA/NSSL and University partners to increase understanding of the Rear-Flank Downdraft/ Forward-Flank Downdraft (RFD/FFD)-Tornado connection in Supercells
- Data assimilation strategy with the goal to double current supercell tornado-warning lead time (15 minutes to 30 minutes) through improved warning accuracy and reduced false alarms
- Leverage the Mobile Research Collaboratory (MRC) and CU Boulder Earth Lab to enable in-field deployment of high-performance computing in support of real-time UAS path-planning for targeted storm observations, and data management
