Black Summer and Pyrocumulonimbus clouds
Pyrocumulonimbus (pyroCb) clouds are thunderstorms that occasionally form above intense bushfire and transport smoke into the stratosphere
"PyroCb events are important sources of stratospheric aerosol. During the Australian forest fires in 2019/2020, such convective plumes transported quantities of smoke into the tropopause region comparable to those of a large volcanic eruption. In this study, we investigate the heat emission threshold at which wildfire plumes transition into pyroCbs."

Das Park Fire in #Kalifornien hat bereits 600 Quadratmeilen verbrannt und erzeugt gefährliche #Pyrocumulonimbus-Wolken (pyroCb). Diese #Rauchgewitterwolken können #Blitze erzeugen, die weitere Brände entfachen. PyroCbs entstehen durch intensive #Hitze und trockenen #Brennstoff und verstärken die #Feuer. #Klimawandel begünstigt ihre Entstehung, und sie beeinflussen das Wetter sowie globale Temperaturen durch die Absorption von #Sonnenlicht.
