Control by the Circulation Transport Outside the Arctic on Transient Response of AMOC to Global Warming
Bibliographic record
Abstract
Using the Alfred Wegener Institute Climate Model (AWI-CM 1.1 LR), we conduct sensitivity experiments separating the Arctic and extra-Arctic warming to investigate the transient response of AMOC to quadrupled carbon dioxide (4×CO2) forcings. The results suggest that AMOC weakening is primarily affected by circulation adjustment induced by the outer-Arctic warming, while the effects of Arctic warming are confined to the polar range and contribute less to AMOC changes. When warming forcing is applied outside the Arctic, the increases of northward advective heat transport dominate the weakening of deep convection in the Nordic Seas, while the reduction of heat loss from ocean to atmosphere is prevalent in Labrador Sea. Besides, the weakening of deep convection in Nordic Seas is more pronounced than in Labrador Sea, implying a leading role of Nordic Seas in the weakening of AMOC under global warming.

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.
