The summer isolated convection regime across the eastern UnitedStates: Geographic extent and regional onset evolution
Bibliographic record
Abstract
Previous studies identified a monsoon-like summer regime of isolated, diurnally-forced convection across the southeastern US (SEUS), but the geographic extent and onset timing of this regime across the eastern US was unresolved. This study focuses on that question using a highresolution radar-based precipitation dataset for a seven-year period. It is found that, on average, onset of the summer isolated convection regime begins in late April in South Florida, extends northward to the Carolinas by mid-May, and to the Canadian border by the end of May. Onset then extends westward from the mid-Atlantic region to just beyond the Mississippi River and as far as east Texas by mid-June. The timing and geographical extent of onset are consistent with previous findings linking this regime with the spring to summer westward migration of the North Atlantic Subtropical High into the SEUS. These results are consistent with the establishment of a more prominent monsoon-like precipitation regime centered in the SEUS as the Earth warms.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
