Short summary
Alpine areas are experiencing substantial changes in temperature and rainfall, both critical triggers for rockfall events. This article proposes a novel approach based on the frequency of meteorological variables to comprehend implication between climatic scenarios and rockfall events in the Dolomites. Several climate variables were considered and the outcomes reveal warming trend, reduction in icing and freeze-thaw cycles leading to an earlier summer onset and a delayed winter end.
