Nonmigrating tides in equinox temperature fields from the Extended Canadian Middle Atmosphere Model (CMAM)
Bibliographic record
Abstract
The extended Canadian Middle Atmosphere model has been analyzed for wave 0, 1 and wave 2 temperature signatures associated with diurnal and semidiurnal migrating and nonmigrating tides. These waves are ubiquitous in the model data and have significant amplitudes relative to the migrating diurnal tide. They are formed both by forcing in the troposphere and through nonlinear interaction in the middle atmosphere. Superposition of the tidal signatures results in significant longitudinal variations in the local derived diurnal and semidiurnal amplitudes and localized regions of convective instability which may be a source for the inversion layers observed in the mesosphere and the bores seen in airglow data. It is conjectured that the dissipation of tidal components can only be understood when they are considered as a system and not as individual components. The superposed tidal fields have a strong geographic dependence. Associated airglow signatures and chemistry will exhibit similar variability.

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.
