Wie Waldbrände Feuerstürme auslösen
Feurige Gewitter: Heftige Waldbrände können verheerende Gewitterstürme erzeugen, die die Flammen weiter anfachen und Rauch bis in die Stratosphäre schleudern – ähnlich wie bei einem Vulkanausbruch. Forschende haben dieses extreme Wetterereignis nun erstmals in einem Klimamodell simuliert. Entscheidend für die Entstehung solcher Infernos ist demnach eine Kombination aus Hitze und Feuchtigkeit. Die Ergebnisse können dabei helfen, Gefahren besser vorherzusehen und bisherige Klimamodelle zu verfeinern.

#GarnetFire in Sierra Nevada is extremely active today--perhaps most active it has been so far, w/large & episodically tall (~30k ft) pyroCb plume. Now over 40k acres & burning in heavy forest, it'll likely burn until sustained rain/snow arrives (none on horizon). #CAfire #CAwx

#GarnetFire making another big/high-intensity run today (could double in size by tomorrow) characterized by multiple big pulses of pyrocumulonimbus (pyroCb, or "fire thunderstorm") activity as it "fills in the gaps" between recent fire footprints in/near Sierra NF. #CAwx #CAfire

Very impressive #pyroCb/#pyrocumulonimbus plume from the Dollar Lake Fire this afternoon in Wyoming! It's currently stretching nearly the entire length of the state with activity still ongoing near the fire. #WYwx

Wát een foto! Bosbranden in Portugal hebben gisteren deze enorme 'buienwolk' geproduceerd. Dit verschijnsel veroorzaakt door een lokale warmtebron, wordt ook wel een Pyrocumulonimbus (PyroCB) genoemd en kan in sommige gevallen ook bliksem geven.

Large scale smoke plumes over Canada and Russia were produced from Pyrocumulonimbus (pyroCb) activity over both countries. Shown in this image are Aerosol Index (AI) measurements from the OMPS sensor onboard the NOAA 21 (N21) satellite overlayed on RGB imagery from N21's VIIRS sensor.

2.5-minute #Himawari9 Visible / Shortwave Infrared / Infrared Window images showed signatures of 3 #pyrocumulonimbus cloud pulses (from 0832-0842 UTC) initiated by a wildfire in South Korea -- these are the first documented #pyroCb events on the Korean Peninsula.

Grampians bushfire on 20 Dec generated pyrocumulonimbus (thunderstorm generated by a fire, defined by cloud tops -40°C or less: in this case -51°C).
