Description:
This repository provides the complete data used to generate all main and supplementary figures for the above-titled study.
Included files:

• Main Figures  – reproducible datasets (e.g., Fig1.nc) for Figures 1 through 4 of the manuscript.

• Supplementary Figures (e.g., Supp_Fig1.nc/) – extended analyses, seasonal breakdowns, and methodological sensitivity tests.
  All figures are derived from hourly reanalysis data (1980–2024) and CMIP6 model projections, processed using Python (xarray, cartopy, matplotlib) following the methods described in the paper.
