Abstract

fetched live from OpenAlex

Recent publications have evaluated topostrophy, τ ≡ f × V · ∇ D where is f Coriolis, V is velocity, and ∇ D is gradient of total depth, as a means of comparing models' circulations. Some results are striking. Comparing four global models, two with modest grid size and two with fine grids, Merryfield and Scott (2007) show that finer grid models are characterized by more positive τ , especially at greater depths and higher latitudes. Among nine Arctic Ocean models, Holloway et al. (2007) find τ in three of the models quite distinct from the other six, a result shown to depend upon subgrid eddy parameterization. From different choices of numerical method within the same model, Penduff et al. (2007) show that improved numerical representations support more positive τ . Can these model results be compared with observations? A global compilation has been prepared from 17120 current meter records, spanning 83087 current meter‐months. The compilation tends to confirm modeling progress achieved by finer resolution, improved parameterizations and better representations. A new characterization of global ocean circulation emerges, with suggestive dynamical insights.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
