Notes on wildfires and volcanic eruptions sergey khaykin

eruption just directly shoots aerosols into the stratosphere.

SAGE III

SAOD HAS NOT RETURNED TO BACKGROUND SINCE 2017

sask/alberta 2024 fires had largest effect in northern hemisphere.

SNPP OMPS-LP

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

GSAW global stratospheric watch latmos.ipsl.fr

wildfires are new emerging source of injection

not observed at all before 2010 - now seasonal - visible by naked eye.

Self-lofting
