Abstract

fetched live from OpenAlex

Tuktoyaktuk, a community along the Beaufort coast in the western Canadian Arctic, experiences serious coastal erosion during periods of strong and persistent northwesterly winds during the late summer season when the sea ice coverage reaches its annual minimum. The prevalence of strong northwesterly winds along the Beaufort coast has often been linked to the passage of powerful storms. In this study, a climatology of late summer winds at Tuktoyaktuk is compiled that links the observed wind regime to the orography of the Brooks Range. The climatology and a detailed case study of an extreme wind event indicate that an anticyclone over the Chukchi or western Beaufort Seas is conducive for cold air damming events north of the Brooks Range that alter the pressure gradient in a direction favorable for strong northwesterly geostrophic winds over Tuktoyaktuk to be mixed to the surface in a neutrally stratified atmosphere.

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.
