Three-Dimensional Cloud-Resolving Modeling of the Flash-Flood Heavy Rainfall Event over Kosovo

Abstract

This study investigates the intense flash-flood heavy rainfall event that struck Kosovo on 24 June 2023, unleashing an unprecedented 54 mm of rainfall within an hour. Employing a state-of-the-art three-dimensional non-hydrostatic cloud-resolving model, the research elucidates the atmospheric processes driving extreme precipitation events. Key findings include the formation of high-altitude cumulonimbus clouds, the role of strong updrafts in promoting intense microphysical vertical transfer, and the subsequent formation of wet downbursts. Validation against radar data confirms the model's accuracy in replicating observed precipitation patterns, enhancing confidence in its predictive capabilities. These findings contribute to advancing our understanding of extreme weather events and hold promise for improved forecasting and risk mitigation strategies.
