The aim of this thesis is to quantify the links between atmospheric circulation changes over Europe and local climatic trends in the second half of the 20th century. We employ several parallel classifications of circulation types that were collected and developed within the COST733 Action “Harmonisation and Applications of Weather Types Classifications for European Regions”. To our knowledge, such a comparative approach has not been used so far. The influence of circulation changes on climatic trends was studied using 11 climatic variables from the Czech Republic and maximum and minimum temperature and precipitation from 29 European stations. There is large variability within the results obtained with different circulation classifications. We only found substantial influence of circulation changes on winter temperature trends, so it is rather the change of climatic properties of individual circulation types (within-type change) that drives most of the observed climatic trends.
