Storm Wind Frequency and Direction, Dempster Highway, Richardson Mountains, Yukon and Northwest Territories
Bibliographic record
Abstract
Maintenance costs have risen since 1996 along the northern Dempster Highway, especially for snow clearing. The purpose of this paper is to investigate the wind regime of the region and determine its association with increased maintenance activities. Hourly wind speed and direction were measured at four sites near the territorial border crossing (YT km 465/NT km 0) for July 2006–December 2018 at the Environment Canada Rock River station (YT km 457) and February 2014 to July 2018 at YT km 421, NT km 8.5, and NT km 51.5. Wind speeds were classified according to the Beaufort Scale and wind type: calm (force 0–1), breeze (2–6), gale (7–9), and storm (10–12). The mean winter wind speed was highest at Rock River (4.1 m/s), followed by km 8.5 (2.4 m/s), km 421 (2.3 m/s), and km 51.5 (2.1 m/s). At all sites the mean wind speed was lower in winter than summer, but the highest winds were measured in the winter. At Rock River, 9.1% of observations were for gale or storm winds, considerably more than at kms 8.5 (0.5%), 51.5 (0.1%), and 421 (1.1%). In Yukon the dominant and strongest winds were easterly off Richardson Mountains, while in the NT the dominant winds were southwesterly, but more variable in direction. There were no apparent increases in winter wind speeds over the period of record. Although Rock River experienced the strongest winds throughout the year, it exhibited the same seasonal trends in wind speed as the other locations. The dominant easterly wind direction at Rock River was consistent with km 421. The valley near Rock River is well nicknamed Hurricane Alley.

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.
