Stratospheric Chemistry and Climate Interactions Impacts of Climate Change on Extreme Weather

Peidong Wang is a Stanford Science Postdoctoral Fellow studying the coupling between stratospheric chemistry and surface climate.

Stratospheric ozone plays a key role in shaping surface climate patterns, such as the Southern Annular Mode, which influence sea surface temperatures, sea ice, and extreme weather across the Southern Hemisphere. Yet the two-way coupling between stratospheric chemistry and the stratosphere–troposphere–ocean system remains underexplored. Peidong leverages thousands of years of pre-industrial control simulations from fully coupled chemistry–climate models to uncover the intrinsic relationship between ozone variability and surface climate. This work provides insights into how chemistry–climate interactions drive climate responses and internal variability.
