Technical Summary Regional Atmospheric Modeling

This goal of this Regional Climate Modelling Activity was to develop projections of regional climate for the Arabian Peninsula at fine spatial and temporal scale, that reflect the large-scale features and temporal trends from Global Climate Model (GCM) simulations (AR5), but also the historical patterns of climate variables at the regional and local scale (Fowler et al. 2007; Wood et al. 2004). To achieve this, a regional climate model (RCM) was deployed that dynamically downscaled the climate of the Arabian Peninsula using GCM data for lateral boundary conditions.
