ABSTRACT. – Changes in Europe’s Temperature Extreme Values. In environmental researches several concerns on the evolution of temperatures. However, in the last decade we can observe intensification of extreme events, including that of temperatures. The present research investigates the evolution of extreme temperature values scaled at annual scale using frequency analysis on historical data. Three types of extreme temperatures were analyzed: annual minimum and maximum, and highest daily temperature fluctuation on annual scale. The results show both the dynamics of changes and probabilistic laws describing the extreme values, obtaining hazard related to these phenomena. We found risky evolutions in case of maximum annual temperatures, when in 55% of locations the associated hazard value was increasing for long or short time period, and in case of highest daily temperature fluctuation, when in 71% of cases the associated hazard value was increasing for long or short time period.
