| 520 | _aNile River is life artery for Egypt; it is the main source for fresh water. Egypt water interests beyond its political borders. Many concerns regard to climate change and climate variability and their impacts on Nile river and its tributaries. Regional climate models one of important tools for investigation of climate. Precipitation is one of important climate elements that affect on climate system and its representation in regional climate models is very significant. We compared 4 convection schemes (kuo-grell with 2 closures (arakawa schubert and fritsch-chappell)-emanuel-tiedtke) quantitative comparison (total precipitation-convective precipitation and surface temperature) for river nile domain (blue nile region and equatorial Lakes region) to find the best convection scheme valid for interested region Tiedtke convection scheme was added to convection scheme sensitivity comparison. For more investigation all variables will be fixed except convection scheme using boundary condition ECMWF-EIN15 reanalysis data from ERA interim for three year period 2003-2005. Boundary condition validation is made by using CRU (surface temperature, total precipitation) and TRMM convective precipitation data. We found that grell convection scheme as most often was more stable in results and give less bias compared with observation specifically Grell_AS was the best especially for equatorial lakes region where Grell_FC give much convective especially for Blue Nile region | ||
