Extended Data Fig. 2: Trend in 6-month SPEI based on CRU-TS and ERA5 during 1981–2022.

Panel a) shows the trends in 6-month SPEI using precipitation and AED from the CRU-TS dataset. Panel b) illustrates the trends in 6-month SPEI derived from precipitation and AED based on ERA5 datasets. Non-significant trends (P-value > 0.05) are marked in gray to improve clarity. The analysis excludes dryland regions with an average annual rainfall of less than 180 mm.
