Abstract
Rotating table experiments are essential in the study of geophysical fluid dynamics (GFD) where planetary rotation is important. They are a valuable research tool that allows one to gain insight into the dynamics of oceanic and atmospheric flows. This chapter describes a different technique for global measurements of dynamic fields. This technique is based on optical altimetry and allows one to measure the slope of the surface elevation in every pixel of the image of the flow. The chapter gives a brief review of the general features of a rotating layer with a free surface, including the so-called polar β-plane approximation. It discusses the experimental technique, including the methods of conversion of the slope of the surface elevation into velocity. The chapter also gives a theoretical description of inertial and Rossby waves. Finally, it presents the examples of different flows studied with the altimetric imaging velocimetry (AIV) technique.

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 it
