There is a great need of constructing regional climate scenarios for the purposes of impact studies. The most sophisticated tools to predict global climate changes are General Circulation Models. Unfortunately, the spatial scale they use is too coarse to represent adequately local climate features. Therefore the problem of great interest is how to project global characteristics of climate variables into regional climate details. One of the approaches is the semi-empirical technique in which local information is estimated using empirical relationships between large scale and regional values.
Various models simulate climate in different way in certain regions.
Discrepancies between models are considerable. It should be useful to provide a kind of preliminary assessment of models' correctness in a given region which would help to choose the most adequate one. Such evaluation has been made for the region of Poland. Monthly means of temperature and precipitation were interpolated from grid values onto Polish meteorological stations and compared with observational data. Historical monthly means were computed from the period 1951-1990.
