A simulation study of seasonal variations in the thermospheric upward propagation of migrating terdiurnal tide
Bibliographic record
Abstract
Abstract In this study, the Thermosphere Ionosphere Electrodynamics Global Circulation Model and the extended Canadian Middle Atmosphere Model are utilized to investigate the seasonal variations of the upward propagation of the migrating terdiurnal tide from the mesosphere and lower thermosphere (MLT). Three main conclusions are drawn from a series of controlled simulations: (1) The background thermospheric zonal and meridional winds and neutral temperature can affect the upward propagation of the terdiurnal tide. (2) The background zonal winds can play an important role in the variation of the vertical advection and adiabatic cooling/heating, especially in the low thermosphere, and as a consequence, the upward propagation of the terdiurnal tide is modulated. (3) The terdiurnal tide in the MLT has influences not only on the latitudinal distributions and magnitudes of the terdiurnal tide in the upper thermosphere but also on the effect of the background winds on the upward propagation of the terdiurnal tide.

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.
