Multi-model climate change analysis over mountainous regions is a complex topic due to the models´ different representations of the mountains. The Andes Mountains produces a huge disturbance of the atmospheric circulation of South America with large differences in the climatic response that occur on the west and eastern side of the range. Due to different representations of the mountain, these sides will differ among the models. Moreover, the climate along the mountain range will present a strong dependence on the topographical high of the grid point, also differing among models, and its distance from the Equator. In order to take under consideration all these elements, we present the first results of a methodology which allows us to objectively classify the domain of simulation following three different criteria: latitudinal bands, topographical height and section of topography (hillside, valley, peak, ...) along the range.
