The smoke has also caused an unusually large number of pyrocumulonimbus (pyrCbs) events, or fire-induced thunderstorms, to form in the skies
new report from NASA
, the smoke from the devastating blazes is “having a dramatic impact on New Zealand, causing severe air quality issues” and has already “traveled halfway around Earth,” reaching across South America. Because of the rate and strength at which the fires are burning and the amount of pollution entering the air, NASA scientists believe the heavy smoke will make “at least one full circuit around the globe” before returning to its origins in Australia.
Researchers from NASA said the smoke has led to an unusually large number of pyrocumulonimbus events, or fire-induced thunderstorms, to form in the skies. These clouds, which act like thunderstorms but do not have precipitation, have formed due to the “searing heat combined with historic dryness” and the “uplift of ash, smoke, and burning material via super-heated updrafts,” according to the space agency.
