In a changing climate, ice‐rich permafrost features such as rock glaciers will experience drastic changes. Modeling the heat transport through the blocky surface layer with its large interstitial pore spaces poses some challenges as various modes of non‐conductive heat transport—advective forms in particular—can occur. Here, we show that the 1D physics‐based model SNOWPACK can be...

The European mountain cryosphere: a review of its current state, trends, and future challenges

Beniston, Martin ; Farinotti, Daniel ; Stoffel, Markus ; Andreassen, Liss M. ; Coppola, Erika ; Eckert, Nicolas ; Fantini, Adriano ; Giacona, Florie ; Hauck, Christian ; Huss, Matthias ; Huwald, Hendrik ; Lehning, Michael ; López-Moreno, Juan-Ignacio ; Magnusson, Jan ; Marty, Christoph ; Morán-Tejéda, Enrique ; Morin, Samuel ; Naaim, Mohamed ; Provenzale, Antonello ; Rabatel, Antoine ; Six, Delphine ; Stötter, Johann ; Strasser, Ulrich ; Terzago, Silvia ; Vincent, Christian

In: The Cryosphere, 2018, vol. 12, no. 2, p. 759–794

The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution. We additionally provide an assessment of current cryosphere research in Europe and point to the different...
