SIMULATION OF DIFFERENT CUMULUS SCHEMES OF WRF MODEL FOR TWO EXTREME EVENTS OVER EGYPT

Document Type : Original Article

Abstract

This work aimed to study two heavy rainfall events over Egypt. The two events occur in January, 17 2010 and 2011. Although both events occur in winter season, their impact was very unusual. In this study an attempt was made to perform diagnostic and prognostic analysis of the events. It was found that the 2010 case was due to interaction between tropical and mid-latitude systems, while the 2011 one was entirely due to mid- latitude systems. WRF model was used to investigate the better scheme from Betts Miller (BM) and Kain Fretch (KF) convective in forecasting rainfall. It is found that BM performance better in predicting the characteristics of the two events.
