Processed data and MATLAB code for seasonal energy-budget contrasts in Tibetan Plateau extreme warm anomalies

This record contains key processed data and MATLAB scripts supporting the analyses of seasonal contrasts in surface energy-budget contributions to extreme warm anomalies over the Tibetan Plateau. The package is designed as a minimal reproducibility archive for verifying the main numerical results, including extreme warm-year identification, warm-anomaly core definitions, surface energy-budget contributions, local meteorological diagnostics, circulation-index statistics and Lasso-based statistical decomposition. Raw ERA5 files are not included because the full raw-data volume is large and the original data are publicly available from the Copernicus Climate Data Store. Instead, this package provides processed MATLAB data files, a compact verification script and workflow/reference scripts documenting the main calculation procedures.
