Our new #E3SM wildfire simulation captures how extreme fires can create their own thunderstorm clouds (pyroCb) by reproducing the 2020 Creek Fire pyroCb — a first in climate modeling.

This is interesting because smoke should not contribute to surface heating. Black carbon warms up the atmosphere but not the SST. Something beyond my understanding is going on.

Independent coverage

this kind of fire eruptions are no longer a disturbance but a new climatology. GCMs must take these aerosols and chemistry into consideration

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.

Pyrocumulonimbus affect average stratospheric aerosol composition The fingerprint of pyrocumulonimbus clouds can be seen in lower stratospheric aerosols.

This study using observational data has shown the contribution of wildfire smokes to the stratospheric composition. Our study is the first step to quantify its impact on climate. We need to treat wildfire pyroCbs as moderate volcanic eruptions. (www.science.org/doi/10.1126/...).
