Gale-force downslope winds in Hurricane Alley, north Dempster Highway, Yukon
Bibliographic record
Abstract
Strong, downslope winds commonly disrupt traffic on the Dempster Highway near the Yukon-NWT border; road closures occur on 25% of winter days.Wind characteristics from regional and local weather stations were analysed and associated with synoptic conditions.Downslope winds form due to a mountain ridge along the territorial border.The ridge is a boundary for wind characteristics: easterlies prevail in the Yukon, westerlies in the NWT, and both in Wright Pass where the highway crosses the border.The ECCC Rock River weather station has recorded 672 easterly windstorms since 2006 and a maximum wind speed of 137 km h -1 .Just 12% of the windstorms occurred in summer, with the remainder equally distributed during the other seasons.Easterly windstorms were commonly associated with extratropical cyclones in the Gulf of Alaska and north-south pressure gradients, and westerly windstorms with south-north gradients and cyclones over the Beaufort Sea.

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.
