🟥 🌩 Pyrocumulonimbus (pyroCb) Clouds are towering, thunderstorm-like cumulonimbus clouds triggered by intense heat from large wildfires or volcanic eruptions. ❤️ 🔁 #PyroCb #FireStormClouds
#PyroCB-looking flare up in NE BC... smoke plume with strong West to East flow gusting 57km/h, heat from wildfire (fed by wind and anomalously warm ~6C above normal) and poof, right past the atmospheric cap.
This is one of the most incredible fire photos I've seen to date!! Photo taken @VerimapI during a thermal scan flight over the Adams Lake fire last night shows a lenticular cloud above a #pyrocb, simply incredible!! #wow #BCwildfire #BCfire
Para que entendáis la diferencia entre un pirocúmulo #PyroCu y un pirocumulonimbo #PyroCb, he traducido esta infografía de la NASA.
Disponer de perfiles LIDAR (entre otros) de las formaciones de pirocúmulos y pirocumulonimbus #PyroCB en incendios forestales puede ser oro puro para analizar su comportamiento.
Un poco más al norte. Los incendios de arriba arden con mucha fuerza...demasiada. Se observan claramente pirocúmulos, incluso quizás #PyroCB
Hay un enorme incendio justo al sureste de #Fairbanks, Alaska🇺🇸 Imagen del Aqua ayer. Se aprecia la formación de potentes pirocúmulos (¿quizá #PyroCB?).
Un enorme pirocúmulo (quizá #PyroCB?) se alza sobre los cielos de Northern Australia ya cerca de la frontera con Queensland. El Niño trae otra potente época de incendios a la mitad norte de Oz donde ya han ardido más de 60 millones de hectáreas este año. (Satélite Aqua):
Krai de Zabaykalsky (Federación Rusa🇷🇺) Satélite Aqua hoy. Si, como creo, esa nube blanca es producto de la brutal convección de uno de los incendios, es una de las nubes convectivas más potentes que nunca haya visto en Asia. Tiene pinta de ser un bestial #PyroCB
At 571,184 hectares and growing, the #DonnieCreek fire in NE BC is an absolute monster. Given how much landscape it has already burnt, the amount of black, charred ground is enough to enhance the local heating and lift, generating its own #PyroCB #BCWildfire #BCstorm
Already 85 #pyroCb events in Canada during the 2023 fire season, which exceeds the second highest total of 50 in 2021 (dataset begins in 2013). Nine pyroCbs occurred on 9-10 July alone. There have been 97 pyroCbs worldwide in 2023. Four more will make 2023 the most active year.
Several pyrocumulonumbus (#pyroCb) events were observed in #Alberta this evening. A small, upper-level weather disturbance is helping to destabilize the atmosphere and aid pyroCb development. Contours are 500 hPa heights and winds. Additional pyroCbs are possible this weekend.
A wildfire in British Columbia produced a #pyrocumulonimbus/#pyroCb cloud yesterday evening - more on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-blog…
Sunday was the fourth day in a row of intense wildfires with #pyroCb activity in Canada. PyroCbs developed over a fire along the #BritishColumbia/NWT border and a large fire complex in central #Alberta. Large pyroCu and possible pyroCbs also occurred west of #Edmonton.
A fire in #Quebec produced at least four "pulses" of #pyroCb activity on Thursday (01 June). By sunset, a train of smoke-filled anvil clouds extended across much of the Gulf of St. Lawrence. This is the latest in a series of pyroCb events in Canada since early May.
A large pyrocumulonimbus (#pyroCb) developed over a fire in #Ontario on 22 June. This brings the pyroCb total in Canada to 51, already making 2023 the most active year of the last decade. The previous benchmark was 50 pyroCbs in 2021, with only one pyroCb observed by this date.
Weather friends in #Kelowna shared this photo of a #pyrocb popping up west of Little White Mountain, view is looking south from their home in Glenmore, it has been reported via *5555 #BCwildfire

Radar rendering of yesterdays' #pyroCb from the #WildcatFire. Mt. Rainier for scale. The lowest radar sweeps are well above the surface, so we can't see the updraft core right above the fire.
The #GarnetFire's transition to #pyroCb is both meteorologically fascinating and alarming. Hoping fire crews can get ahead of these dangerous conditions.
#GarnetFire yielding deepening #pyroCu and edging toward #pyroCb. Its updraft also appears to be perturbing the upper level flow with a persistent cloud lens forming aloft, which is then perforated by the plume at the end of the loop.
There is a decent chance the #GarnetFire will produce a #pyroCb today. The well-established fire burning in forest fuels has been active through the night, is already producing a modest plume and #pyroCu, and there is an influx of mid-level moisture. The "inverted-V" profile (

Here is a rotating view of the plume structure during the period of peak depth. There are two distinct detrainment levels for the smoke, the first at a lower inversion layer that the plume punched through and the second near the top of the #pyroCb
Radar summary of yesterday's deep plume and #pyroCb development from the #GarnetFire. The fire is now burning toward/into the Teakettle Experimental Forest, a location that helped me fall in love with the Sierra and my wife. (share.watchduty.org/i/61327?ts=175…)

Here is a radar summary of the multiple distinct #pyroCb pulses from the #EmigrantFire today (times are in UTC, which is PDT+7 hrs).
Timelapse footage of the #EmigrantFire pyrocumulonimbus this evening. Note the corkscrew motion of the plume and the constant pileus clouds developing over it as it rises. #orwx
The radar correlation coefficient data clearly show the development of hydrometeors in the upper plume immediately above the fire, as opposed to displaced downwind as is often the case. #EmigrantFire #pyroCb
Impressive rapid initiation of a morning #pyroCb from the #EmigrantFire.

Quick radar summary of today's #PyroCb plume from the #DollarLakeFire burning near the head of the #GreenRiver. Hope nobody is trapped up there seeing as this is near a popular access point to the #WindRiverMountains
It's been a summer of fire-breathing smoke storms in North America. Scientists have tracked thunderstorms created by #wildfires for years. However, the ferocity of the pyrocumulonimbus, or #pyroCb, events that have popped up in #Canada has surprised them. earthobservatory.nasa.gov/images/148630/…
Turns out the #CranstonFire actually produced a #pyroCumulonimbus (#pyroCb) cloud - #GOES16 Visible/Shortwave Infrared/Infrared Window images: AnimGIF go.wisc.edu/c7sj2r | MP4 go.wisc.edu/2x7a9r #CAwx

GOES indicating lightning with the #pyroCb over the #DixieFire. Other thunderstorms in the vicinity. Going to be a long day/night with plume-dominated fire behavior, outflow winds, lightning, and potential column collapse(s) #CAfire #CAwx

Boom goes the dynamite. #longfire producing rapid #pyroCb development with a substantial anvil aloft. Satellite data indicate cold cloud tops and hot fire (at 1.6 um)
And now its producing deep #pyroCb
Cranking up now, with deeper and more widespread #pyroCu likely to transition to #pyroCb. I think this is the #FallsFire
#SABurshfires Imagen del satélite Suomi NPP de hace creo unas 6-8 horas. Es Kangaroo Island. Lo que señala la flecha es un posible pirocúmulo #PyroCb
Here's a time-lapse video of the #WilliamsFlatsFire (depicting conditions on Aug 8th from 10pm til 11:30pm). Credit: Rocky Raybell Photography flickr.com/photos/rockyra… #WaWILDFIRE #PyroCb
#AustraliaBushfires #PyroCb Estoy casi seguro de que todas esas zonas que señalo han formado pirocúmulos. Hoy es uno de los peores días que recuerdo al respecto en meses.
Outbreak of at least four thunderstorms generated by wildfire (#pyroCb) in Northern #California over the #DixieFire, #AntelopeFire, and #McFarlandFire. Note the smoky anvil clouds at about 30,000 ft. Dixie Fire produced pyroCbs from two separate regions of the fire front. #CAwx
Right now trough #goes16 #realearth new #PyroCb blowing in the fire between #Bolivia #Paraguay the FOURTH this season. Lot to learn @bomberscat @FireWeatherLab and to discuss
