13 MENA

CORDEX Middle East North Africa (MENA)

The CORDEX MENA domain, which includes North Africa, southern Europe, and the whole Arabian Peninsula, offers considerable challenges for assessing and understanding climate change over the region due to its large size and complex topography. It includes highland areas (e.g., Atlas Mountains, Ethiopian Highlands, Iranian and Anatolian plateaus), wide coastal areas, and desert areas (Sahara in Africa and Rub Al-Khali in the Arabian Peninsula).

Model domain

For CORDEX MENA, the simulations were performed on a rotated grid with the pole at 180°W longitude and 90°N latitude. The domain covers approximately the region from about 27°W to 76°E longitude and 7°S to 45°N latitude.

Simulations were carried out using two different resolutions: 0.44° (approx. 50 km) and 0.22° (approx. 25 km) to investigate the effects of increasing spatial resolution on the quality of results. ERA-Interim driven simulations have been performed over the period is 1979-2011, using both resolutions. Climate projections have been performed over the 21st century according to the RCP4.5 scenario, using both resolutions.
