Short summary
This study investigates hourly precipitation patterns and extremes across Italy using the MERIDA HRES reanalysis, a dataset that combines observations and weather models to reconstruct past atmospheric conditions. By analising 37 years of hourly data, the study identifies an increase in hourly extreme precipitation in Alpine areas during summer and southern coastal regions in autumn, providing insights into evolving precipitation patterns and supporting climate resilience planning.
