During a thunderstorm , it ’s normally the lightning bolts that take over Instagram — after all , it ’s a niggling difficult to apply the X - Pro II filter to a soundwave . That is , if you ’re a heliophysicist arm with rockets , your own lightning bolt , and some heavy scientific discipline .
In a newspaper presented today at a meeting of the American Geophysical Union , Maher Dayeh from the Southwest Research Institute in San Antonio revealed elaborated acoustic maps he ’d made of a lightning bolt — an image of thunder , in other lyric .
To get the data , Dayeh break to a U.S. military installation in Florida , and fired a garden rocket trailling a copper wire into a cloud during a thunderstorm . The skyrocket trip a lightning bolt , which travelled down the wire , allowing the team to read the thunder with 15 microphones set a metre apart . That produced the acoustic maps you could see above .
The experiments allowed Dayeh to map out the acoustics of a bombshell with “ surprising detail ” — and they also discovered that the loudness of a bombshell depend on the efflorescence galvanizing stream flowing through the lightning bolt . Plus , the great unwashed scram to shoot rockets into swarm and make lightning bolt . scientific discipline . [ 2015 Joint Assembly , Nature ]
