Listening to Tornadoes to increase warning times and save lives

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.
