Abstract The paper presents characteristics of eastern Serbia climate based on data collected at four main meteorological (Crni Vrh, Negotin, Niš and Zaječar) and two climatological stations (Knjaževac and Sokobanja) over 30 years of climate measurements (1981-2010). To analyse general climatic conditions, monthly, seasonal and annual values of air temperature and precipitation regimes are shown. For a better understanding of climate and climate-vegetation classification, the following climate indices were processed: Lang’s rain factor as the basis for climate-vegetation classification of climate, pluviometric hazard, De Mortonne’s index of aridity, Köerner’s thermodrome coefficient and Ellenberg's climate coefficient. The geographical climate-vegetation classification is based on Walter's climate diagram, the Thornthwaite classification system and UNEP. Lang's bioclimatic classification indicates that Crni Vrh is the most humid, and Niš the most arid. According to Thornthwaite, the research area is dominated by the dry subhumid climate, C1 type. According to the UNEP classification, the entire study area has a humid climate. The values of Ellenberg's climate coefficient indicate the zone of oak forests with the characteristics of a dry climate at all stations, except the Crni Crh station which is in the zone of beech forests and has a humid climate. According to De Mortonne’s index of aridity, exorheism prevails in the study area. Köerner's thermodrome coefficient shows that Niš weather station has a moderate continental climate, Crni Vrh a low continental or mountain climate, and other stations show pronounced continentality. Based on Walter's climate diagrams, we can conclude that the research area has a continental climate.
