Abstract: In June 2010, the University of baby直播app and University of Nebraska collaborated for the first collection of thermodynamic data in a supercell thunderstorm using an unmanned aircraft system (UAS) as part of the 鈥淪econd Verification of the Origins of Rotation in Tornadoes Experiment鈥 (VORTEX-2). In 2019, the CU-NU UAS team again deployed to the Great Plains with new and improved UAS and storm-intercept strategies for the project 鈥淭argeted Observations by Radars and UAS of Supercells鈥 (TORUS). The 2019 TORUS field campaign was highlighted by intercepts of several supercells that produced tornadoes while UAS were sampling the storms.

The TORUS field campaign also provided an opportunity to deploy balloon-borne instruments to begin to characterize how supercells, that can grow above 70,000 feet, generate disturbances in the stratosphere as part of the Hypersonic Flight in the Turbulent Stratosphere (HYFLITS) project. The objectives of HYFLITS research are to measure turbulence and particulates in the stratosphere, and to refine models for the design of hypersonic aircraft. This talk will review the TORUS and HYFLITS campaigns and discuss contributions to severe weather research and efforts to characterize the stratosphere for hypersonic aircraft.
