A Numerical Study of Circulation and Associated Variability in the Intra-Americas Sea
Bibliographic record
Abstract
A three-dimensional, data-assimilative, regional ocean circulation model is used in simulating circulation, hydrography and associated variability in the Intra-Americas Sea (IAS). The model domain covers the region between 8°N and 32°N and 99°W and 54°W, with a horizontal resolution of 1/6°. The ocean circulation model is driven by 6 hourly wind fields produced by the National Centers for Environmental Prediction and boundary forcing extracted from 5-day reanalysis data produced by the British Atmospheric Data Centre. The model is integrated for 3 years from January 1999 to December 2001. The model performance is assessed by comparing model results with oceanographic observations made in the IAS during this period. Model results are used in the study of the "compensation effect" in which transport variations through the Yucatan Channel are partially compensated by flow through the Old Bahama and Northwest Providence Channels. The compensation effect is found to be associated with baroclinic (2-layer) flow through the Yucatan Channel at timescales longer than 20 days, while at shorter timescales (less than 20 days) the vertical structure of the flow is barotropic.

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.
