Bilans de masse des glaciers alpins et scandinaves, leurs relations avec l'oscillation du climat de l'Atlantique nord

Abstract

This paper considers the relations between the North Atlantic Oscillation, reflecting the climate variation patterns on the North Atlantic region, and mass balance variations of Alpine and Scandinavian glaciers. This study first enhances the mass balance representativeness of climate variations on the massif scale. However, dealing with glaciers in the North and the South of Europe, the mass balance variations are inversely correlated. Analyses comparing the mass balance variations and the NAO index show that annual trends between these two components are really poor, but at the decadal scale, the two signals are well correlated.
