Abstract

fetched live from OpenAlex

Potential predictability of seasonal precipitation over the US is explored using a new canonical ensemble correlation (CEC) prediction model, which optimally utilizes intrinsic sea surface temperature (SST) variability in major ocean basins. Results show that CEC yields a remarkable (10–20%) increase in baseline prediction skills for seasonal precipitation over the US for all seasons, compared to traditional statistical predictions using global SST. While the tropical Pacific, i.e., El Niño, contributes to the largest share of potential predictability in the southern tier States during boreal winter, the North Pacific and the North Atlantic are responsible for enhanced predictability in the northern Great Plains, Midwest and the southwest US during boreal summer. Overall, CEC significantly reduces the spring‐summer predictability barrier over the conterminous US, thereby raising the skill bar for seasonal precipitation predictions.

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.
