Abstract

fetched live from OpenAlex

A moist turbulence model based on the shallow Boussinesq equations with a simple condensation scheme is introduced. Its key advantage is its ability to express the major dynamical effects of moisture on turbulence while maintaining computational efficiency. Because of its simple condensation scheme and periodic boundary conditions, the majority of the computational and memory expense can go towards increased resolution. Sensitivity experiments were performed on a test case of moist bubble simulations. We find that timestep choices that satisfy the CFL condition give adequate temporal resolution. Also addressed are other numerical issues regarding spurious oscillations in fields, in particular in the moisture variables. A ‘hole-filled’ experiment, which removes the negative liquid water and partially smooths the vapour and liquid water fields, indicates that these issues are not important for such a high-resolution model and field-smoothing schemes are not worth the increase in computation expense or lowered accuracy. The moist bubble test cases also span a large range of resolutions, from 903 to 3843. The higher resolutions show shallow liquid water spectra, implying that resolution is key to correct modelling of moist atmospheric dynamics.

Not 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.
