Abstract
The chapter reviews the evidence for the influence of Antarctic and Arctic ozone changes on the troposphere and ocean, and the mechanisms underlying this coupling. Antarctic ozone depletion has driven a cooling and strengthening of the polar vortex in austral spring. Models and observations show that this change has also been associated with a strengthening and poleward shift of the midlatitude westerly winds in the Southern Hemisphere troposphere in austral summer, as well as a cooling of the Antarctic troposphere. Antarctic ozone depletion has been associated with summer trends in surface temperature over Antarctica, precipitation over the southern hemisphere, Southern Ocean circulation, and ocean-atmosphere fluxes of carbon dioxide over the Southern Ocean. Both radiative and dynamical mechanisms are thought to be involved in communicating the response to stratospheric ozone depletion to the troposphere. In the Arctic there is some modeling evidence suggestive of a link between ozone depletion and tropospheric circulation changes, but due to the weaker ozone trends and larger internal variability, no such relationship has been identified in the observations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
