100-year mass changes in the Swiss Alps linked to the Atlantic multidecadal oscillation

Huss, Matthias ; Hock, Regine ; Bauder, Andreas ; Funk, Martin

In: Geophysical Research Letters, 2010, vol. 37, p. L10501

Thirty new 100-year records of glacier surface mass balance, accumulation and melt in the Swiss Alps are presented. The time series are based on a comprehensive set of field data and distributed modeling and provide insights into the glacier-climate linkage. Considerable mass loss over the 20th century is evident for all glaciers, but rates differ strongly. Glacier mass loss shows multidecadal...

Snow accumulation distribution inferred from time-lapse photography and simple modelling

Farinotti, Daniel ; Magnusson, Jan ; Huss, Matthias ; Bauder, Andreas

In: Hydrological Processes, 2010, p. -

The spatial and temporal distribution of snow accumulation is complex and significantly influences the hydrological characteristics of mountain catchments. Many snow redistribution processes, such as avalanching, slushflow or wind drift, are controlled by topography, but their modelling remains challenging. In situ measurements of snow accumulation are laborious and generally have a coarse...

Strong Alpine glacier melt in the 1940s due to enhanced solar radiation

Huss, Matthias ; Funk, M. ; Ohmura, A.

In: Geophysical Research Letters, 2009, vol. 36, p. L23501

A 94-year time series of annual glacier melt at four high elevation sites in the European Alps is used to investigate the effect of global dimming and brightening of solar radiation on glacier mass balance. Snow and ice melt was stronger in the 1940s than in recent years, in spite of significantly higher air temperatures in the present decade. An inner Alpine radiation record shows that in the...
