What is it about?
Tornado producing storms emit sound at frequencies below human hearing up to 2 hours before a tornado forms. This paper discusses current understanding of the emitted noise and outlines challenges with integrating these measurements with unmanned aerial systems (drones).
Why is it important?
If we can understand the mechanism for the sound production then we can use the signals to understand the active fluid mechanisms that produce tornadoes and other severe weather events.
