Peak Runoff Timing Is Linked to Global Warming Trajectories
Bibliographic record
Abstract
Abstract The earth's hydroclimate is continuing to change, and the corresponding impacts on water resource space‐time distribution need to be understood to mitigate their socioeconomic consequences. A variety of ecosystem services, transport processes, and human activities are synced with the timing of peak annual runoff. To understand the influence of changing hydroclimate on peak runoff dates across the continental United States, we downscaled outputs of 10 Global Circulation Models for different future scenarios. Our results quantify robust spatial patterns of both negative (up to 3–5 weeks) and positive (up to 2–4 weeks) shifts in the dates of peak annual runoff occurrence by the end of this century. In snowmelt‐dominated areas, annual maxima are projected to shift to earlier dates due to the corresponding changes in snow accumulation timing. For regions in which the occurrence of springtime extreme soil wetness shifts to later time, we find that peak annual runoff is also projected to be delayed. These patterns of runoff timing change tend to be more pronounced for projections of higher greenhouse concentration in the future.

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; both teacher heads agree on what is shown here.
