UPWELLING INTO THE LOWER STRATOSPHERE & TROPICAL WAVE BREAKING: EVIDENCE FROM CHEMICAL TRACERS
Bibliographic record
Abstract
We use 2005 - 2010 measurements from the Microwave Limb Sounder (MLS) instrument\nto calculate the deseasonalized anomalies of tropical mean water vapor (H2O), carbon\nmonoxide (CO), and nitrous oxide (N2O) on the 68 hPa surface. We then calculate\nthe spatial maps of the coherence between the tropical mean tracer measurements and\nreanalysis temperature on the 100 hPa surface, in both the subseasonal and multiyear time\nwindows. In the multiyear time window, the spatial pattern of the coherence, and the time\nlags, indicate that fluctuations in 100 hPa temperature affect 68 hPa H2O through changes\nin dehydration efficiency. In the subseasonal time window, the coherence between 100\nhPa temperature and 68 hPa H2O is mediated through changes in upwelling driven by the\ndissipation of tropical Rossby waves. On subseasonal timescales, the 68 hPa anomalies in\ntropical mean CO are strongly coherent with the Madden Julian Oscillation (MJO).

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.
