Abstract
Drought prediction is vital for sustaining water security in regions highly exposed to climate change. Here we present a machine learning-based method that integrates climate model outputs to improve drought monitoring in the Middle East. We introduce a spatially adaptive index called the Geographically Weighted Temperature Vegetation Dryness Index, developed using local regression techniques and trend analysis. This index integrates temperature and vegetation signals while accounting for variations across space and time. It substantially improves prediction accuracy compared to previous methods. We used recent climate projections under three socioeconomic scenarios to estimate future drought patterns. Results show spatial shifts and intensification of drought conditions in parts of the region by the end of the century under high-emission conditions. Our method also detects localized drought hotspots that broader indices may miss, offering valuable insights for targeted and adaptive water resource planning. Drought conditions could intensify by 25–35% in the future in the Middle East under a high-emissions scenario, with the most affected regions concentrated in central and southern areas, according to a drought index based on ensemble machine learning methods and climate model simulations.

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 it
