Cross-equatorial flow of grounded abyssal ocean currents
Bibliographic record
Abstract
AbstractThe cross-equatorial flow of grounded abyssal ocean currents in a differentially rotating meridional channel with parabolic bottom topography is examined. In particular, the dependence is determined of the cross-equatorial volume flux on the underlying flow parameters including the slope of the channel’s walls , the half-width of the channel , the half-width and height of the abyssal current and , respectively, the magnitude of the rotation vector , the Earth’s radius , and the reduced gravity . In addition, it is shown that the ratio between the width of the channel and the zonal wavelength of a narrow wave structure that is formed by the current in the equatorial region plays a crucial role in determining into which hemisphere the current flows after its interaction with the equator. It is found that some parameters (e.g. and ) do not have any significant effect on the zonal wavelength, while variations in other parameters (e.g. , , , and ) change the zonal wavelength and, consequently, can dramatically alter the qualitative trans-equatorial behavior of the abyssal current. After examining an auxiliary model of a particle in a rotating equatorial channel, it is shown that the zonal wavelength of the equatorial wave is linearly proportional to the equatorial length scale defined as , where is the equatorial value of the beta-parameter.Keywords: Cross-equatorial flowsGrounded abyssal ocean currentsDeep western boundary currents AcknowledgementsPreparation of this paper was partially supported by Research Grants awarded by the Natural Sciences and Engineering Research Council of Canada to G.E.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
