Watch: Listening to Tornadoes
19 June 2020
Last update: 19/06/20 10:57
Before a tornado forms the pressure drop at the centre emits a dull tone at 5-10Hz which can be detected hours before it becomes dangerous.
Brian Elbing at Oklahoma State University has devised a detection system that works up to 300 miles away from the source and can predict the size and strength of the tornado before it forms, providing advanced warning for at-risk areas. Interview with University of Oxford Mathematician Dr Tom Crawford.
This video is part of a collaboration between FYFD and the Journal of Fluid Mechanics featuring a series of interviews with researchers from the APS DFD 2017 conference.
Sponsored by FYFD, the Journal of Fluid Mechanics, and the UK Fluids Network. Produced by Tom Crawford and Nicole Sharp with assistance from A.J. Fillo.
