I know there's some static precip during a sandstorm, enough to detect by similar means, so it makes sense, although I would think that it would be physically obvious the tornado is approaching your pos before you could discern the threat on the radio.


You're close. When I was a kid, and we had black and white TV's with dials, we would dial in channel 13 and tune it until it was just blacked out, then dial in channel 2. You can actually watch lightning strikes as white flashes, and when a tornado touches down, the whole screen turns white. Yes, it really works.
