Wind-packing of snow: How do wind crusts form?

Wind-packing of snow is the process responsible for the formation of wind slabs and wind crusts. These are hard layers of well-sintered snow often found in the snowpack in mountains as well as in polar regions. Wind-packing affects the local mass balance, ...

Impact of Extreme Land Surface Heterogeneity on Micrometeorology over Spring Snow Cover

Michael Lehning, Sebastian Schlögl

The melting mountain snow cover in spring typically changes from a continuous snow cover to a mosaic of patches of snow and bare ground, inducing an extreme heterogeneity of the land surface. A comprehensive measurement campaign, the Dischma experiment, wa ...

Influence of slope-scale snowmelt on catchment response simulated with the Alpine3D model

Michael Lehning, Wolf Hendrik Huwald, Ernesto Trujillo Gomez, Tristan Jonas Brauchli

Snow and hydrological modeling in alpine environments remains challenging because of the complexity of the processes affecting the mass and energy balance. This study examines the influence of snowmelt on the hydrological response of a high-alpine catchmen ...

Cubic zirconia in >2370◦C impact melt records Earth’s hottest crust

Cyril Cayron

Bolide impacts influence primordial evolution of planetary bodies because they can cause instantaneous melting and vaporization of both crust and impactors. Temperatures reached by impact-generated silicate melts are unknown because meteorite impacts are e ...

Climate-Induced Changes in Spring Snowmelt Impact Ecosystem Metabolism and Carbon Fluxes in an Alpine Stream Network

Tom Ian Battin, Enrico Bertuzzo, Amber Joy Ulseth

Although stream ecosystems are recognized as an important component of the global carbon cycle, the impacts of climate-induced hydrological extremes on carbon fluxes in stream networks remain unclear. Using continuous measurements of ecosystem metabolism, ...

Modulation of snow reflectance and snowmelt from Central Asian glaciers by anthropogenic black carbon

Julia Schmale, Yang Li

Deposited mineral dust and black carbon are known to reduce the albedo of snow and enhance melt. Here we estimate the contribution of anthropogenic black carbon (BC) to snowmelt in glacier accumulation zones of Central Asia based on in-situ measurements an ...

Streamwater pCO2in an Alpine Headwater Catchment

Tom Ian Battin, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

Boreal and alpine streams are highly sensitive to climate change. Previous studies have shown the relevance of streams for carbon cycling in boreal landscapes. Less work has been done on alpine streams, and we do not understand the contributions from these ...

Mountain shading influence on spatial interpolation of direct shortwave radiation for snowmelt modeling

The hydrology of alpine areas is highly snow-dependent. Snowmelt, as a major component of the hydrologic cycle, influences the streams hydrology and biogeochemistry and is important to take into account in water resources management. Modeling snow distribu ...

Modelling liquid water transport in snow under rain-on-snow conditions – considering preferential flow

Michael Lehning, Nander Wever, Sebastian Würzer, Tobias Jonas

Rain on snow (ROS) has the potential to generate severe floods. Thus, precisely predicting the effect of an approaching ROS event on runoff formation is very important. Data analyses from past ROS events have shown that a snowpack experiencing ROS can eith ...

Spring snowmelt drives ecosystem metabolism in an Alpine stream network

Tom Ian Battin, Enrico Bertuzzo, Amber Joy Ulseth

Stream ecosystem metabolism modulates organic carbon (OC) cycling in rivers and regulates downstream OC fluxes. Climate-change scenarios predict precipitation to shift from snow towards rain in alpine ecosystems, however consequences of this shift to strea ...
