HONG KONG: For the very first time, in a unique, ground-breaking experiment, a team of scientists have captured images of thunder. Yes, you read that right: pictures of sound.
Or, rather, what we perceive to be sound, as lead researcher Dr. Maher A. Dayeh points out: “Lightning strikes the Earth more than 4 million times a day, yet the physics behind this violent process remain poorly understood. While we understand the general mechanics of thunder generation, it’s not particularly clear which physical processes of the lightning discharge contribute to the thunder we hear. A listener perceives thunder largely based upon the distance from lightning. From nearby, thunder has a sharp, cracking sound. From farther away, it has a longer-lasting, rumbling nature.”
This, then, exposes one of the most significant questions we still have in regards to thunder.
