Variability of atmospheric winds and waves in the Arctic polar mesosphere during a stratospheric sudden warming
Bibliographic record
Abstract
A ground‐based wide angle Michelson Interferometer was used to monitor the temporal variation of winds and waves in the mesopause region at Resolute Bay, Canada (74.9°N, 94.9°W) during a stratospheric warming event of February 2001. Observed variability of zonal and meridional winds is compared to the daily mean temperature fields at 3.16 hPa from assimilated stratospheric data. Reversal of eastward zonal winds is seen to occur during maximum mean temperatures in the stratospheric polar cap. Spectral analysis of the wind‐velocity time series shows the evolution of different periodicities and their amplitudes. A cool period between two warming events shows a decrease in the amplitude of the semi‐diurnal tide and an increase in the power of waves shorter than 12 hours before peak stratospheric temperatures are reached.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
