Phys.org   September 28, 2023 Exceptionally high-energy lightning strokes >106 J (X1000 stronger than average) in the very low-frequency band between 5 and 18 kHz, also known as superbolts (SB), occur mostly during winter over the North-East Atlantic, the Mediterranean Sea, and over the Altiplano in South America. An international team of researchers (Israel, USA- University of Washington) compared the World-Wide Lightning Location Network database with meteorological and aerosol data to examine the causes of lightning stroke high energies. Their results showed that the energy per stroke increases sharply as the distance between the cloud’s charging zone (where the cloud electrification […]
