摘要

Lightning during thunderstorms is a common phenomenon. Cloud-to-ground lightning bolts are also quite common - about 100 strike Earth's surface every single second - and their power is extraordinary. Till now it was difficult to experimentally determine the voltage that develops within thunderclouds. Over the past several decades, researchers have flown airplanes and balloons into the centres of thunderstorms to study their electrical structure, but they could only probe a small region and not the entire cloud. Now, in a new effort, researchers have developed a way to capture one critical measurement of an entire storm - its electric potential. A team of scientists from several institutions in India and Japan has found that it is possible to use a muon detector to measure electric potential in thunderstorms and their finding is an astounding 1.3 billion volts (GV), which is 10 times greater than the largest value ever reported (Physical Review Letters, 15 March 2019 | DOI: 10.1103/ PhysRevLett.122.105101).
