Spying on a Storm's Infrasonic Signals to Improve Tornado Warnings

Tornado survivors often compare the terrifying, deafening roars of a twister’s furious winds to the sound of a freight train.

But storms also emit sounds that are inaudible to human ears right before producing a tornado.

By detecting these infrasonic waves from miles away, researchers hope to develop an earlier, more accurate tornado warning system.

Today, weather agencies issue tornado warnings by closely observing storms for characteristic air movements.

The high rate of error causes ‘warning fatigue,’ which can be deadly.

Elbing is trying to understand the secrets held by a storm’s infrasonic signals in order to increase warning time, make warnings more accurate, and improve tornado prediction.
