PRESENT CLIMATE, GCM-BIASES AND EXPECTED CHANGES ALONG ONE ZONAL AND ONE MERIDIONAL BELT, CROSSING IN EAST-CENTRAL EUROPE
Geographical zonality and continentality are presented. The global climate models (GCM) and the ERA-40 adjusted observations are called to answer three questions: (i.) How do these peculiarities appear in the observed climate of single meridional and zonal belts around the Globe? (ii.) Can the model...
