The interannual variability of the surface air temperature (SAT) in the Arctic region, including the Barents Sea, is studied on based of use ERA-Interim re-analysis data for the period 1979-2017. The mean SAT map, root-mean-square values and coefficients of linear trend maps are constructed. The obtained estimates are compared with observational data, and with the influence of large-scale atmospheric circulation processes. The relationship between the different types of the atmospheric circulation over the region and the spatial distribution of surface air temperature on seasonal and interannual scales is analyzed. The relevance of the study is determined by the need to study the physical patterns of intensive atmospheric circulation development over the Arctic, the trends of their inter-annual variability, and the relationships with surface air temperature anomalies on the long-term scales.
