Abstract

fetched live from OpenAlex

Two Canadian Warmings(CWs) in December 1965 and November 1968 were chosen to investigate the circulation characteristics of CWs.Weak warming was observed at the middle and lower levels of the stratosphere in the two CW cases.Accompanying the weak warming,the westerly in the stratosphere changed to an easterly one,but lasted only a short while.The circulation anomaly in both CW cases was weaker compared to that in the stratospheric sudden warming(SSW).The pre-conditioned process that was observed in the SSW case was not observed in the two CW cases.As the main factor of the stratospheric disturbance,the upward planetary wave was enhanced prior to and after day 0 of the two CW cases,unlike in the SSW case.Arctic Oscillation(AO) evolution was employed to show the downward stratospheric vortex circulation anomaly.Although the two CWs caused an AO anomaly in the high stratosphere,the AO anomaly barely reached the lower troposphere.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
