Evaluation of a regional climate model using in situ temperature observations over the Balkan Peninsula

摘要: Climate model data provide large, dense coverage and long time-series, characteristics that are advantageous in the study of climate. However, it is not recommended such be used any region without prior evaluation their reliability based on comparisons with situ observations. In this study, accuracy maximum minimum temperature from ALADIN-Climate regional climate (with a 25-km horizontal resolution driven at lateral boundaries by ERA-40 reanalysis) have been assessed for 53 stations across Balkan Peninsula. The temperatures corresponding to each station were extracted nearest land grids. first compared observations subsequently examined ability identify extreme events. general, was found quite accurate describing seasonal cycle, as well simulating spatial distribution temperature. Simulations more realistic along coastlines, highlighting constraints topographic forcing simulations. Assessing performance determine extremes (warm cold spells), better detecting spells has tendency toward overestimating frequency occurrence warm spells, particularly summer.
