Internal Gravity Waves and Convection Generated by a Thermal Forcing in the Atmosphere
Bibliographic record
Abstract
In this thesis, we present a mathematical model that represents internal gravity waves and convection generated by a thermal forcing in the atmosphere.The goal is to investigate the mechanisms by which deep heating and convection in the lower atmosphere generate internal gravity waves.We consider a two-dimensional two-layer model of the atmosphere comprising an upper layer with stable stratification and an unstable convective lower layer.The governing equations are based on the equations for conservation of mass, momentum and energy for a fluid.The thermal forcing is represented by a nonhomogeneous term in the energy conservation equation.We study different configurations depending on the vertical structure and depth of the thermal forcing.

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.
