Low frequency variability of atmospheric circulation over Europe between 1785 and 1994

Abstract: A decadal analysis of monthly sea level pressure fields over Europe and the adjacent North Atlantic with a correlation-based classification scheme results in 12 classes. These classes show a high variability in the frequencies of their occurrence and also in the combination between the different classes. The range of the frequency changes from one decade to another can differ up to a factor 2. The class 1 high index situation with high positive values of the North Atlantic Oscillation Index (NAOI) with a westerly flow into the continent shows an increasing frequency in the last decades, which is unique in the analyzed period of 210 years. The combinations between the different classes are not the same over the whole period of the 210 years and show differences between the 19th century and the middle of the 20th century: especially in winter, spring and autumn. In summer the most remarkable deviations are found in the Greenland Sea. While the Azores high is present very regularly, t.... https://www.erdkunde.uni-bonn.de/article/view/2381
