Could a laser pointer be just as effective as Mjolnir in controlling lightning? Scientists have discovered the largest electrical current ever. “This will provide valuable information for establishing limits to the scale of lightning — including megaflashes — for engineering, safety and scientific concerns.”. But these records also forced scientists to rethink the definition of lightning. To put that in perspective, that would be roughly the distance from Oklahoma City to Dallas, TX. On July 24, 1947, the most powerful lightning strike ever recorded in the United States struck the Cathedral of Learning of the University of Pittsburgh. The most powerful lightning storm ever detected on Saturn has been captured by the Cassini spacecraft – but scientists are still not sure what is causing it. If storms are particularly strong and atmospheric conditions are just right, these powerful thunderbolts can travel tens or hundreds of miles. Called “positive” lightning, these monster bolts may develop a billion (10e9) volts versus ground, and an associated charge of 350 Coulombs. This is the longest lightning bolt ever recorded, stretching 199.5 … This is many times hotter than the surface of the sun.

Lightning data are live and update every minute. The stations can “listen” for lightning-produced radio waves by tuning in to the very low-frequency range of 5 to 18 kilohertz. Scientists from the University of Alabama found that typical afternoon lightning varies from 6,000 to 20,000 amps while powerful morning lightning to … 19 SEPTEMBER 2016. There could be a lower risk—the lower the flash rate—but it’s not ‘no-risk.’”. Space-based lightning mapping allows scientists to measure full flash extent and precise durations of megaflashes over broad geospatial territories. A bolt can carry between 10 and 100 million volts. See lightning strikes in real time across the planet. On June 20, 2007, during a thunder storm in Oklahoma, a lighting bolt streaked across half the state. Cookie Policy It is likely that even greater extremes still exist, and that we will be able to observe them as lightning detection technology improves,” said Professor Randall Cerveny, chief investigator of Weather and Climate Extremes for WMO. Most lightning is considered “negative lighting” in which a cloud unleashes a negative charge to the ground. We have also kept records on some of the worst lightning strikes ever recorded. The most powerful lightning storm ever detected on Saturn has been captured by the Cassini spacecraft – but scientists are still not sure what is causing it. The bolt discharged approximately 345,000 amps This was enough electricity to briefly light 600,000 60W light bulbs “[B]ecause of continued improvements in meteorology and climatology technology and analysis, climate experts can now monitor and detect weather events such as specific lightning flashes in much greater detail than ever before,” Randall Cerveny, Rapporteur of Climate and Weather Extremes for WMO says in the press release.
