Richard Heene of the Science Detective Research Group believes its possible to detect tornadoes up to two hours sooner than ever before by tracking them through very low frequency (VLF) sound waves.
But in order to test his theory, he needs film and audio footage of between 20 to 30 tornadoes. Heene figures that by linking up the video and audio signals, he can identify certain sounds that mark dangerous periods during storms and create a predictive measurement for future twisters.
Time is of the essence for Heene, who wants to do his twisted research during May, when as many as 500 twisters are expected to roll through South Dakota, Texas and Oklahoma.
Any video camera will work, but participating storm chasers need a device called a VLF receiver that converts the low frequency sounds emitted by the twisters into tones that can be heard by human ears.
