Standard point error statistics, calculated from grid point and basin aggregated data, and precipitation related climate indices are used to analyze the performance of the different models in representing the main spatial and temporal features of the regional climate, and its extreme events. As a whole, the ENSEMBLES models are found to achieve a good representation of those features, with good spatial correlations with observations. There is a small but relevant negative bias in precipitation, especially in the driest months, leading to systematic errors in related climate indices. The underprediction of precipitation occurs in most percentiles, although this deficiency is partially corrected at the basin level. Interestingly, some of the conclusions concerning the performance of the models are different of what has been found for the contiguous territory of Spain; in particular, ENSEMBLES models appear too dry over Portugal and too wet over Spain. Finally, models behave quite differently in the simulation of some important aspects of local climate, from the mean climatology to high precipitation regimes in localized mountain ranges and in the subsequent drier regions.<\/jats:p>","DOI":"10.1029\/2011jd016768","type":"journal-article","created":{"date-parts":[[2012,3,13]],"date-time":"2012-03-13T13:16:05Z","timestamp":1331644565000},"source":"Crossref","is-referenced-by-count":54,"title":["Assessment of the ENSEMBLES regional climate models in the representation of precipitation variability and extremes over Portugal"],"prefix":"10.1029","volume":"117","author":[{"given":"Pedro M.
