The paper analyzes changes in extreme temperature indices over the Peripannonian
region of Bosnia and Herzegovina. Data on daily minimum and maximum temperatures during
the period 1961–2016 from four meteorological stations were used for the calculation in the
RClimDex (1.0) sopware trends in 16 indices recommended by the Expert team on climate change
detection and indices. 0e estimated significant upward tendency in indices of warm extremes
and downward in cold-related indices confirm that warming is present. 0e highest trend values
were obtained for indices TXx, TNn, TN90p, TX90p, SU25, SU30 and WSDI. 0e results indicate
significant distributional changes in the period 1987−2016 compared to the period 1961−1990.
A significant positive (negative) correlation between the East-Atlantic pattern and indices of
warm (cold) extremes was determined throughout the year. In winter and spring, significant
links to the North Atlantic Oscillation and the Arctic Oscillation, respectively, were also found.
