Spatiotemporal Variability and Recent Anomalies of ERA5-Derived Precipitation Extremes over North Sumatra, 2011-2025
This study utilizes ERA5 data and a multi-index framework to characterize the spatiotemporal variability of precipitation extremes in North Sumatra from 2011 to 2025, revealing that recent years, particularly 2023–2025, exhibited significant and spatially heterogeneous anomalies that cannot be captured by annual rainfall totals alone.
