与分辨率为25 × 25 km的高分辨率区域气候模式相比，高分辨率区域气候模式（10 × 10 km）在有效模拟希腊气候特征（温度、降水和风）方面的能力得到了检验和分析。总体而言，结果表明，更精细的分辨率模型在高海拔地区产生冬季低温，岛屿和周围海洋之间的温差，山区的高降雨总量，夏季的热风暴，以及爱琴海的风极大值方面表现出更好的技能。关于未来的预测，即使这两个模式同意的气候信号，差异被发现主要是选定的参数的变化幅度。最后，发现在较高的气压水平，目前的两个模式的预测没有显示出显着的差异，因为地形和地形不发挥这样重要的作用，作为一般大气环流。
The ability of a fine resolution regional climate model (10 × 10 km) in simulating efficiently the climate characteristics (temperature, precipitation, and wind) over Greece, in comparison to the previous version of the model with a 25 × 25 km resolution, is examined and analyzed in the present study. Overall, the results showed that the finer resolution model presented a better skill in generating low winter temperatures at high altitudinal areas, the temperature difference between the islands and the surrounding sea, high rainfall totals over the mountainous areas, the thermal storms during summer, and the wind maxima over the Aegean Sea. Regarding the future projections, even though the two models agree on the climatic signal, differences are found mainly to the magnitude of change of the selected parameters. Finally, it was found that at higher pressure levels, the present day projections of the two models do not show significant differences since the topography and terrain does not play such an important role as the general atmospheric circulation.
