Sažetak: U radu su predstavljene promjene temperature vazduha i njihova prostorna raspodjela u Republici Srpskoj. Istraživanja su vršena za periode 1961-1990. i 1999-2008, na bazi meteoroloških podataka i statističkih modela interpolacije, zasnovanim na regresionim modelima. Upotrebom visinskog modela terena (DEM), te konstruisane regresione jednačine i Kriging modela prostorne interpolacije u GIS softverskoj aplikaciji MapInfo izračunate su vrijednosti srednjih temperatura vazduha za kompletnu površinu posmatranog prostora. Dobijeni rezultati istraživanja pokazuju da je najveći trend povećanja temperatura, na godišnjem nivou, u sjeverozapadnom i sjeveroistočnom dijelu Republike Srpske, odnosno na području Posavine. Na području centralnog planinskog pojasa registrovana su neznatna povećanja temperature vazduha, dok je na području istočnog dijela visokog hercegovačkog krša prisutan, čak, blagi pad temperatura vazduha.
Ključne riječi: Republika Srpska, temperatura vazduha, klimatske promjene, interpolacija, GIS.

Abstract: This paper aims to present the changes in air temperature and its spatial distribution in Republic of Srpska. The research was conducted in the periods 1961-1990 and 1999-2008, based on meteorological data and statistical interpolation model, acted on regression models. By using high-altitude terrain model (DEM), a constructed regression equation and Kriging interpolation of spatial models in MapInfo GIS software application, we calculated the values of average air temperature for all surfaces of the space observed. The results showed that the biggest trend of increasing temperature, per annum, was at the northwest and northeast of Republika Srpska and in the area of Posavina. There was only a slight increase of air temperature in the area of the central mountain belt, whereas in the eastern highland Herzegovina karsts region we measured temperature drops.
Key words: Republika Srpska, air temperature, climate changes, interpolation, GIS.
