Abstract

fetched live from OpenAlex

Low moved southward and then eastward but with a trough extending across southern Canada. Over the southern two-thirds of the North American continent on February 5 (fig. 6), easterly flow had become established in a temperature field indicating increase of wind speed with height. 3. CONCLUDING REMARKS The manner in which the polar night stratospheric jet stream and its associated cold core annually drift away from the pole and lose strength has only recently become observable through increasing amounts of data at 25 mb. and above. Although each year the breakup tends to occur on a different date and in a different region, it is usually accompanied by a spectacular sequence of events. The sequence of events in 1958, as illustrated here, differed strikingly from that of 1957 when the cold air entered the United States through western Canada just prior to the appearance of “explosive ” warming 25 mb. over Newfoundland. The abnormally warm air then moved northward across Greenland. In March 1956, warming moved into central and southern Canada from the Alaskan region but was not accompanied by a rapid breakdown of the circumpolar Low. Other cases studied, dating back to 1948, show a variety of breakup times and magnitudes of stratospheric warming.

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.
