Climate Impacts of the Decadal and Interannual Variability of the Atlantic Thermohaline Circulation in Bergen Climate Model
Bibliographic record
Abstract
Climate impacts of the basin-scale and local-scale oscillations of the Atlantic thermohaline circulation (THC) are identified by using Bergen Climate Model (BCM). The basin-wide oscillation occurs at decadal scales with strong cross-equatorial flow, the more localized fluctuation of the THC occurs mainly at interannual scales with weaker cross-equatorial flow. The basin-wide THC oscillation is associated with an intensified Azores high and Icelandic low,the local-scale THC adjustment is accompanied with a negative phase-like North Atlantic Oscillation (NAO). The atmospheric circulation change results in an intensified deep convection in the Labrador Sea in both cases. For the local-scale THC adjustment, the Irminger Sea is dominated by a weakened convection. Surface salinity anomalies in the Labrador Sea are created locally by evaporation anomalies at the sinking regions. Further analyses support that the local-scale THC oscillation is caused passively by the atmosphere forcing. There are evidences indicating that the whole THC conveyor accelerating generates the warmer sub-polar SST, which warms the air and enhances the surface evaporation.

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.
