Abstract: Knowledge of characteristics of future climate is essential to create adaptation plans. Numerical models can provide such information but an important issue is the correct assessment of reliability. This important problem can be solved by evaluating the ability of a model to reproduce past climate. It is assumed that the type and amount of error in the reference period is transferred to a scenario period. In this paper, the reconstruction of precipitation in 1971–1990 period by models selected from the EU ENSEMBLES project was analyzed. Analyses were subjected to precipitation conditions described by climatic indices based on daily sum of precipitation. Climate indices maps were compared by two methods. The first method is called optical flow method, and consists of assessing the parameters of a local transformation of fields. The second method uses the cluster analysis technique to a combined field consisting of reconstructed and reference values. These methods allow to perform an objectified evaluation of climate simulations.
