LIGHTNING

June 29, 2020

A World Meteorological Organisation (WMO) committee of experts said two new world records for the longest reported distance and the longest reported duration for a single lightning flash were set in Brazil and Argentina.

About:

A single Lightning flash stretched more than 700 kilometres across Brazil on October 31 last year has created a new world record for the longest reported distance of lightning. This was equivalent to the distance between Boston and Washington in the US, or between London and Basel in Switzerland.
A lightning flash that developed continuously over northern Argentina on March 4, 2019 lasted a whopping 16.73 seconds creating new world record for the longest reported duration of lightning.
The new records for extreme lightning bursts, or 'megaflashes', during 2019, are more than double the size and duration of the previous record flashes.
The new record-breaking strikes were released on the occasion of International Lightning Safety Day on June 28.
