we did new parameterizations in the model to represent this kind of convections. It is so amazing that this kind of convections (pyroCbs) has comparable horizontal and vertical scale. The implementations are to balance the local pyroCb formation and global representation of its dispersion.

Excited to share a new publication led by @drdavepeterson.bsky.social with contributions by Mike Fromm, René Servranckx and others, that analyzes the inventory of all known, worldwide, observed pyroCb events from 2013-2023! www.nature.com/articles/s41...

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

#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

Yesterday was a terrible #pyroCB #lightning event in #BCwx and into #ABwx. Between 3pm June 30 and 6am July 1 (Pacific Time), the North American Lightning Detection Network detected 710,117 total lightning events.

Mid-September and it looks like a pyrocb (fire generated thunderstorm) has developed in nern BC. GOES 18 Geocolor image below.

Today's environment had the ingredients for deep pyroCb formation from the get-go. The final factor (clearing cloud cover) arrived late afternoon, and boom.
Needless to say, significant expansion to evac zones southward along CR 5/Hwy 13 corridors for the Lee Fire today. #COwx #LeeFire

ago it was almost unheard of to have a PyroCB in Southern California, but now it's becoming a staple of what we experience here. We used to teach it as a NorCal or other area phenomena, to know about in case you went on a strike team elsewhere, but now we show Ted and Arnie and the Station Fire...

Hello. I'm looking to talk with a meteorologist who specializes in fire weather — most specifically, PyroCb and PyroCu — on the record for an assignment. Looking into what research into these events and overshooting tops can tell us about wildfire spread/severity. Feel free to DM here/other place.

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.

PS: Good luck 4 today.
Let's hope fire auths have prepaired commensurately w/ bad conditions. They should b ready to auto deploy VLHTs & VLATs for rapid 1st response while ground crews r on their way.
There is no such thing as response overkill on dangerous fire-weather days like this. PyroCB risk.

👏 🎉 Congrats to AU Environmental Science Prof. Valentina Aquila for receiving supplemental funding of $96,585 (new total: $388,755) from NASA for the project "Estimating the impacts of volcanic aerosol and pyroCb smoke on model forecasts and data assimilation using the GEOS Analysis Increments."

Here is another animation from @zoom.earth showing the #fire activity in #Alberta during the day and how the approaching outflow boundary helped trigger a PyroCb with the wildfire just West of Fort McMurray. 🔥🌩️

Trans-Pacific transport of smoke from the #AustralianWildFires observed by @JPSSProgram SNPP/OMPS between Dec 29, 2019 & Jan 6, 2020. Some smoke was injected to stratospheric altitudes (= highest Aerosol Index values) in #pyroCumulonimbus clouds. #pyroCb

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).

While it may not look very robust, the #pyroCb near the UT/CO produced an EF-2 tornado on Saturday. The 00Z sounding from Grand Junction, CO shows a classic inverted-v pyroCb sounding with some instability beyond any fire-induced modification.

A series of pyroCb events in Alaska over the last few days have combined with high altitude windws to produce a smoke plume that stretches across Alaska, through western Canada / US, and into California / Nevada. This image shows N20 OMPS AI measurements. The length of the plume is over 4500 km.
