Regional Climate Modelling and Regional Hydrological Modelling Applications in the Arab Region

This Technical Note serves as an explanatory reference that describes the work undertaken on regional climate modelling and regional hydrological modelling within the framework of the Regional Initiative for the Assessment of Climate Change Impacts on Water Resources and Socio-Economic Vulnerability in the Arab Region (RICCAR). The intention is to provide technical clarification of the regional climate modelling methodology and regional hydrological modelling methodology applied by the Swedish Meteorological and Hydrological Institute (SMHI) to generate the regional projections and findings presented in the Arab Climate Change Assessment Report- Main Report and its Technical Annex, which are issued under RICCAR in coordination with the United Nations Economic and Social Commission for Western Asia (ESCWA) and the other RICCAR implementing partners.
