| ABSTRACT | Understanding the impacts of climate change in the Mediterranean is quite challenging due to the complex morphological, geographical, historical and societal characteristics of the region. The majority of the studies examine the climate change impacts in the specific region with the use of regional climate models under high horizontal resolutions and different future emissions scenarios. In addition, an important feature of the recent and ongoing regional model development is the evaluation and quantification of model performance by comparison against reference data.
In this study we evaluate a set of RCM historical simulations carried out in the framework of EURO-CORDEX and MED-CORDEX. The horizontal resolution of the simulations is about 12km (0.11o) and covers the period 1980-2005 on a daily basis. We focus on two variables, temperature and precipitation, while as a reference data set we use the state-of-the-art publicly available E-OBS gridded dataset as well as available station data for both variables. Beside from the analysis of seasonal mean biases for each experiment separately as well to an ensemble of them, we also apply trend analysis on climatic indices regarding the maximum and minimum temperatures and precipitation. The analysis reveals that the models tend to reproduce quite well the observed patterns of temperature whereas a more variable behavior is shown for precipitation. |
