Scherler, Martin ; Hauck, Christian ; Hoelzle, Martin ; Salzmann, Nadine

In: Journal of Geophysical Research: Earth Surface, 2013, vol. 18, no. 2, p. 780–794

Climate change as projected by contemporary general circulation models (GCMs) and regional climate models (RCMs) will have a great impact on high latitude and high mountain permafrost. A process-based one-dimensional permafrost model is used to evaluate the sensitivity of two characteristic alpine permafrost sites to changes in climate for a 110 year time period starting 1991 and ending 2100...

Meltwater infiltration into the frozen active layer at an alpine permafrost site

Scherler, Martin ; Hauck, Christian ; Hoelzle, Martin ; Stähli, Manfred ; Völksch, Ingo

A coupled heat and mass transfer model simulating mass and energy balance of the soil-snow-atmosphere boundary layer was applied to simulate ground temperatures, together with water and ice content evolution, in the active layer of an alpine permafrost site on Schilthorn, Swiss Alps. Abrupt shifts and subsequent fluctuations in ground temperature observed in alpine permafrost boreholes at the...
