Intraseasonal Canadian Winter Temperature Responses to Interannual and Interdecadal Pacific SST Modulations
Bibliographic record
Abstract
The influence of the modal structures of the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) on the wintertime intraseasonal temperatures and temperature extremes over Canada has been analyzed for the 1900–2008 period. Results demonstrate that intraseasonal temperature variability (longer than 11 days) dominates with a high degree of persistence in western Canada, whereas synoptic-scale variability (shorter than 11 days) prevails in eastern Canada. The PDO has been found to exert a significant modulating effect on ENSO-related intraseasonal temperature impacts in western Canada. In eastern Canada, temperature anomalies are generally weaker, often with ENSO and the PDO producing opposite effects. Spectral analysis shows reddening of the temperature spectra with significant peaks near the 20-day period in western Canada. In contrast, the power of the spectra is weaker with significant peaks occurring near the 13-day period in eastern Canada.

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.
