Flash Flood Simulation over Egypt using RegCM3

This study aims to simulate the extraordinary flash flood event that occurred in Egypt from November 1-2, 1994, and evaluate the RegCM3 model's capability to capture the severe mesoscale processes responsible for this storm. The model was set up with different resolutions (40 km and 60 km) and employed various convective and cumulus schemes. The analysis includes synoptic situations and precipitation observations for the specified dates, providing insights into the storm's dynamics and the model's effectiveness in simulating such extreme weather events.
