To better understand how the stratosphere plays an important role in our climate system, this session invites papers that study: (1) Stratospheric transport and dynamics, including but not limited to trace (e.g., age of air, ozone) transport, Brewer-Dobson circulation (BDC), quasi-biennial oscillation (QBO), stratospheric turbulence, wave activities, and sudden stratospheric warming (SSW). (2) Stratospheric aerosols from either nature (e.g., volcano eruptions) or anthropogenic activities (e.g., rocket/aircraft emissions, satellite re-entry, stratospheric aerosol injections), such as aerosol/plume dispersion and transport, aerosol nucleation and microphysical growth, and aerosol radiative effects. (3) Interactions between stratosphere and troposphere, including stratosphere-troposphere exchange (STE) and stratospheric influences on surface climate. Observational, modeling, and theoretical studies are all welcome in this session. As a recent extreme stratospheric perturbation, we also invite studies regarding atmospheric impacts of the Hunga volcanic eruption in January 2022.
