Influence of sun cups on surface albedo of wet Alpine snowpack
Michael Lehning, Mathias Thierry Pierre Bavay, Francesca Carletti
In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...
2024Impact of intercepted and sub-canopy snow microstructure on snowpack response to rain-on-snow events under a boreal canopy
Michael Lehning, Adrien Michel, Nander Wever, Daniel Nadeau, Benjamin Bouchard
Rain-on-snow events can cause severe flooding in snow-dominated regions. These are expected to become more frequent in the future as climate change shifts the precipitation from snowfall to rainfall. However, little is known about how winter rainfall inter ...
2024Surface snow isotopic composition: Post-depositional processes in an alpine snowpack
Michael Lehning, Luca Bianchi, Yoann Nicolas Sadowski
Stable water isotopes are natural tracers allowing to reconstruct the history of a water parcel. They are used as climate proxies and to better understand the hydrological cycle. The snow isotopic composition is directly influenced by temperatures and atmo ...
2022Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland
Jana Freiin von Freyberg, Ilja van Meerveld
When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...
2021Recent patterns of discharge and sediment output of the Gorner Glacier, Switzerland
Recent climate change is causing rapid retreat of alpine glaciers around the globe. As ice melts and glaciers thin, glacier motion and subglacial processes will change. One of the most relevant aspects for down-valley environments, settlements and infrastr ...
