WWLLN does not capture peak seasonal lightning densities, it does represent Evaluation with independent observational networks shows that while the Total number of strokes detected globally was constant, mean stroke powerĭecreases significantly from a peak in 2013 to the lowest levels on record inĢ020. The midlatitudes of the Northern Hemisphere from 2016–2020. With more lightning in the tropics from 2012–2015 and increasing lightning in We also noticed substantial temporal variability over the 11 years of record, Terrestrial regions of the Americas, Africa, and the Maritime Continent, but Shows the well-known pattern of greatest density over the three tropical Strokes detected increases from 2010–2014, an adjustment for detectionĮfficiency reduces this artificial trend. The World Wide Lightning Location Network (WWLLN). Time series and climatology of lightning stroke density based on raw data from Here, weĪnalyze global lightning activity over the second decade of theĢ1st century using a new global, high-resolution gridded Lightning occurrence and distribution are currently freely available. Influence on the Earth system, but few long-term observational datasets of Lightning is an important atmospheric phenomenon and has wide-ranging
