Nonlinear equatorial Kelvin waves and CISK. II: Finite‐amplitude analysis and the leading edge of a cloud region
Bibliographic record
Abstract
Abstract Kelvin wave‐OSK (Conditional Instability of the Second Kind) is studied as a possible explanation for the intraseasonal oscillations of the equatorial troposphere. In this second part of the paper, the finite‐amplitude analysis is performed. It is shown that if one assumes that (he temperature field is separable for the vertical coordinate, then all variables are separable in terms of the vertical coordinate, in the cloud region or in the clear area. Under the assumption that the temperature is separable, it was found that Kelvin waves with finite amplitude when coupled with cumulus heating are never unstable; this conclusion is the same as for the waves in the small‐amplitude approximation in part I. The rarefaction wave at the leading edge of a cloud region is analysed in detail. The analysis can be done only with the finite‐amplitude approximation because of the requirement of genuine nonlinearity.

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.
