Global models can characterize the large scale weather systems that affect the Arabian Peninsula, but not the fine scale processes associated with local terrain and land cover. To capture these smaller scale features, a simulation at sufficiently high spatial resolution of the local complex terrain and the heterogeneous land surfaces is necessary. Investigation of the climate change issue began with Global Climate Models (GCMs), but recently climate scientists took advanced a step by using high resolution dynamical downscaling models to investigate climate change in particular regions. Using a higher resolution regional model to examine a regional will provide an enhanced results in terms of interactions between land, atmosphere, and ocean; convection and microphysics; and cloud, aerosol, and radiation. In this study, we used the Weather Research and Forecasting (WRF) model as a Regional Climate Model (RCM), to dynamically downscale GCM output to the Arabian Peninsula, and especially, Kuwait using three nested domains at grid resolutions of 48 km, 12 km, and 4 km. The main motivation of this study is to use a high resolution regional model to investigate the changes in summer surface Temperatures in the future. Read more..
