Flash Flood

Simulation over Egyptusing RegCM3

Dr. H. Hasanean Abdel Tawab ShalabyBakr A.M. Badawy


Objective

  • The aim of the work to simulate the flash flood of November 1-2,1994, and study the ability of the RegCM3 to describe the sever mesoscale process responsible for development of the unusually intensive Storm of November 1-2, 1994


Model Setup

  • Domain Area:

    • (20° W to 45° E & 15° S to 40° N) cover EgyptArea

  • Case Study:

    • Flash Flood Event ( 1,2 November 1994 )

  • Two Simulations:,

    • 40 km Resolution

    • 60 Km Resolution

  • Different Convective and Cumulus Schemes:

    • Arakawa-Schubert & Anthes-Kuo

    • Arakawa-Schubert & Scheme Grell

    • Fritsch-Chappell & Anthes-Kuo

    • Fritsch-Chappell & Scheme Grell
