Abstract
AbstractMountain glaciers in Scandinavia are currently advancing while most of the monitored mountain glaciers of the world are retreating. We examine atmospheric circulation variability and compare changes in air pressure indices to changes in the mass balance of glaciers in the northeastern part of the Atlantic Ocean. The glacier mass balance correlates well with the strength of maritime flow in both winter and summer, the presence of high pressure over the Barents Sea being a critical factor in summer. The advance of Scandinavian glaciers is due partly to persistently strong westerlies over the northeastern Atlantic during post-1980 winters and partly to cold summertime flow, which together have helped maintain positive glacier net balance by decreasing ablation since 1980.
