Abstract

fetched live from OpenAlex

Abstract Based on unprecedented 22‐year records from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) and the Global Precipitation Measurement (GPM) dual‐frequency precipitation radar (DPR), this study aims to investigate the global distribution and linkage between both convections and precipitation extremes quasi‐globally. Overall, the spatial distributions of extreme events show significant regional variability and land‐ocean contrast. Extreme precipitation is dominant over tropical ocean while extreme convections are exclusive over land from tropics to higher latitude. Besides, there are strong positive relationships between extreme convections and precipitation based on multiple threshold‐based definitions of extremes, which provides more consistent physical properties of extreme events globally. The correlation is significant over land but relatively weak over oceans. Seasonal occurrences of extreme events are also examined. Furthermore, extreme events exhibit notable diurnal characteristics over global land with most extreme convections occurring in the afternoon, while diurnal cycles are more homogeneous over ocean.

Teacher imitation

Not 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.
