104 MONTHLY WEATHER REVIEW APsrr. 1954 THE WEATHER AND CIRCULATION OF APRIL 1954' A Month With a Coduent Jet Stream CONFLUENCE AND THE THERMAL GRADIENT
Bibliographic record
Abstract
The most striking feature of the general circulation of April 1954 was the extremely strong poleward temperature gradient which prevailed dong the northern border of the United States, as indicated by the zonal orientation and crowding of isotherms in this area on the monthly mean charts for sea level (Chart I-A) and upper levels from 850 to 300 mb. (Charts XII-XV). The anomalies of temperature at sea level (Chart I-B) and for the layer from 1000 to 700 mb. (fig. 1) show that this month's meridional temperature contrast was much greater than the April normal. Figure 1 highlights the contrast between abnormally warm conditions in the southern three-quarters of the United States and extremely cold temperatures (as much as 12 ' C. below normal) in practically all of Canada. On many days of the month

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.
