New WMO Certified Megaflash Lightning Extremes for Flash Distance (709 km) and Duration (16.73 seconds) recorded from Space

doi:10.1029/2020GL088888

Identification and validation of atmospheric extremes is essential to monitoring climate change, to addressing engineering and safety concerns, and to promoting technological advancement. An international World Meteorological Organization evaluation committee has critically adjudicated and recommended acceptance of two lightning megaflash events (horizontal mesoscale lightning discharges of 100s km in length) as new global extremes using analysis of Geostationary Lightning Mapper (GLM) data. The world’s greatest extent for an individual lightning flash is a single flash that covered a horizontal distance of 709 ± 8 km (441 ± 5 mi) across parts of southern Brazil on 31 October 2018. The greatest duration for a single lightning flash is 16.730 ± 0.002 seconds from a flash that developed continuously over northern Argentina on 4 March 2019.

英文摘要	Identification and validation of atmospheric extremes is essential to monitoring climate change, to addressing engineering and safety concerns, and to promoting technological advancement. An international World Meteorological Organization evaluation committee has critically adjudicated and recommended acceptance of two lightning megaflash events (horizontal mesoscale lightning discharges of 100s km in length) as new global extremes using analysis of Geostationary Lightning Mapper (GLM) data. The world’s greatest extent for an individual lightning flash is a single flash that covered a horizontal distance of 709 ± 8 km (441 ± 5 mi) across parts of southern Brazil on 31 October 2018. The greatest duration for a single lightning flash is 16.730 ± 0.002 seconds from a flash that developed continuously over northern Argentina on 4 March 2019.
