| Zusammenfassung: | Glacier mass balance is one of the most important indicators in terms of glacier sensitivity to the changing climatic conditions. Particularly the maritime Norwegian glaciers increased in mass until the beginning of the 2000s, whereas Alpine glaciers mainly experienced mass loss. To investigate the different behaviour of Alpine and Scandinavian glaciers, 18 glaciers ? ten in the Alps and eight in Scandinavia ? have been chosen for analysis of mass balances. For detailed analyses, including meteorological and atmospheric parameters, five glaciers ? two in the Alps, two in Norway and one in Sweden - have been selected. Analyses indicate that especially Norwegian glaciers (e.g. Nigardsbreen), situated at or near the western coast, have extreme high mass turnovers and are therefore highly dependent and influenced by the amount of winter precipitation which results in high sensitivity of glaciers to the changing climate. So, for the maritime influenced glaciers in the Alps (i.e. Gries glacier) and Scandinavia (e.g. Alfotbreen, Nigardsbreen), the winter precipitation and therefore the winter balance are the main factors in terms of annual net mass balance. The more continental situated glaciers, such as the Vernagtferner in the Eastern Alps and Storglaciären in the Kebnekaise massif, however, are, due to their location and lower mass turnover, extremely influenced by summer precipitation and temperature. A high correlation between summer balance and summer temperatures has been observed which strengthens the idea of the high importance of the summer balance in terms of the net mass balance on continental glaciers. Between the parameters winter mass balance, NAO (December ? March)and winter precipitation, a significant correlations of maritime glaciers have been observed. The continental situated glaciers however, show low to no correlations of these parameters. ; eng |
