Short summary
Long-lived rising bubbles of wildfire smoke or volcanic aerosol contained within strong vortices have been observed in the stratosphere. Heating through absorption of solar radiation has been hypothesised as driving these structures. We present simple models incorporating two-way interaction between dynamics and aerosol combined with insight from vortex dynamics to explain aspects of observed behaviours, including ascent rate and vorticity magnitude, and to suggest criteria for formation.
