Li, S., W. Liu, L. Zhang, W.J.M. Seviour, and , 2026: Stratospheric ozone depletion causes Southern Ocean surface cooling. Geophys. Res. Lett., 53, no. 13, e2025GL120200, doi:10.1029/2025GL120200.
Stratospheric ozone depletion strongly influences Southern Ocean climate change. Using coupled climate model simulations, here we quantify the transient effect of stratospheric ozone depletion on sea surface temperature (SST) over the Southern Ocean from 1982 to 2005. We find that stratospheric ozone depletion intensifies surface zonal winds to the south of 4°S, which increases northward Ekman transports and promotes cold water advection, resulting in SST cooling there. Meanwhile, meridional SST gradients enhance across the Southern Ocean, which, in turn, prompting colder water advection driven by climatological surface winds to exacerbate the SST cooling between 46°S and 60.S. Because of the continuous increase of stratospheric ozone depletion from 1982 to 2005, the sustained Ekman transport induced horizontal cold-water advection — though partially compensated by changes in surface heat flux and vertical advection below the mixed layers — plays a central role in maintaining Southern Ocean SST cooling and regional sea ice expansion around Antarctica.
