Short summary

Over the Cévennes–Vivarais region in southern France, 5 h intensive rainfall covering an area of 1000 km² with more than 50 mm rain accumulation was observed during IOP7a of HyMeX. This study evaluates the performance of a bin-resolved cloud model for simulating this heavy-precipitation event. The simulation results were compared with observations of rain accumulation, radar reflectivity, temporal and spatial evolution of precipitation, 5 min rain rates, and raindrop size distributions.
