UIIC 551.~.1:651.613~3)"1972.05" WEATHER AND CIRCULATION OF MAY 1972 Continued Drought in the Southwest
Bibliographic record
Abstract
Large circulation changes took place from April to May as the relatively flat, high-latitude flow pattern of April (Wagner 1972) broke down into a highly amplified pattern during May (figs. 1-3). Mean 700-mb Lows moved southward over both northern Asia and the North Pacific Ocean, accompanied by a return of the westerlies to more normal latitudes (fig. 4). Height anomaly changes over the mid-Pacific were especially striking (fig. 3). Here, a mean trough replaced a mean ridge. This reversal markedly shortened the wavelength across the Pacific, quite in keeping with the observed decline of the mid-tropospheric westerlies to near-normal values after the relatively high speeds of April. To the east of the deepening mid-Pacific trough, a strong ridge developed over western Canada and Alaska, surmounting a fairly active low-latitude trough near California. The pre-existing blocking ridge near Hudson Bay strengthened to the south during May and continued to be a dominant factor in the weather over the United States. South of the blocking ridge, heights were subnormal over much of the southern half of the Nation, and the 700-mb westerlies were observed well south of their normal position. The normal buildup of the upper level continental ridge in late spring was thus delayed. The 700-

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
