eruption just directly shoots aerosols into the stratosphere.

an argument you hear fairly frequently is component of a longer oscillation,
once in stratosphere, particle lifespan is not limited by recipitation
once fire intensity is high enough, causes pyro clouds
Canada is the main contributor to wildfire

smoke
black carbon in smoke absorbs visible light, once above 15 km, causes a huge vortex, “self-lofting” “smoke charged vortex” - increases residence time
really beautiful visualizations and videos - ask where can access?
ERA5 and lidar
gorgeous 3d mode;s of vortex
“bubble sampling” of a grid
hunga tongs added 13% of all water vapor in stratosphere
increased
heard timing
he calls 2024 “Panboreal wildfire”
Ipral and atlid
just as intense injection into stratosphere as hunga tomga
weather forecast in franve was 4 deg too warm after smoke cloud injected. Canada cooling france quite efficiently

wildfires are new emerging source of injection
not observed at all before 2010 - now seasonal - visible by naked eye.
