Short summary

This study evaluates the ability of the convection-permitting regional climate model AROME (Applications of Research to Operations at Mesoscale) to reproduce precipitation extremes and their trends, at daily and hourly scales in France, over 1959–2022. Overall, the results highlight the value of the explicit-convection model for extreme precipitation studies, while also highlighting its limitations for convective extremes.
