Uruguay-Argentina joint record for lightning up to 17.102 seconds
New York,Geneva: 770 km in the US in 2020. The longest lightning strike is the world record ever. The attacker was killed shortly after noon in front of a police recruitment center in the southern state of Mississippi. It is 770 kms. So the distance between London and Hamburg, Germany was a long lightning strike. The World Meteorological Organization (WMO) has also described the lightning strike as the world’s longest lightning strike.
The United Nations’ intergovernmental agency said on Tuesday that the true length of a lightning strike in the southern states of the United States on April 29, 2020, was 768 km or 477.2 miles. However, on a horizontal basis, the power was 768 plus eight kilometers (7.5 plus five miles). Thus this glare distance can be said to be equal to the distance between New York and Columbus Ohio in America.
In addition, the record for the longest lightning strike is jointly held by Uruguay and northern Argentina. The incident is of 18 June 2020. At that time the lightning flashed and lasted for 17.102 plus 0.002 seconds.
Also the record for longest megaflash is 60 km longer than the previous record and its distance is 709 plus 8 km. (440.6 miles plus five miles). The event was celebrated in southern Brazil on 31 October 2018. The maximum great circle distance method was used for the previous record and the new record.
The longest duration of the previous megaflash was 16.73 seconds, created from a single flash and was observed over northern Argentina on March 4, 2019. Its duration was 0.37 seconds less than Megaflash’s previous record. All these findings have been published in the Bulletin of the American Meteorological Society.
