Quantifying Particle Numbers and Mass Flux in Drifting Snow

Michael Lehning, Enrico Paterna, Philip Crivelli

We compare two of the most common methods of quantifying mass flux, particle numbers and particle-size distribution for drifting snow events, the snow-particle counter (SPC), a laser-diode-based particle detector, and particle tracking velocimetry based on ...

Wind slab formation in snow: experimental setup and first results.

Michael Lehning, Christian Gabriel Sommer, Charles Fierz

Geophys . Res. Abstr. 18: EGU2016‐11274. The formation of wind-hardened surface layers, also known as wind slabs or wind crusts, is studied. Better knowledge about which processes and parameters are important will lead to an improved understanding of the m ...

Changes in snow distribution and surface topography following a snowstorm on Antarctic sea ice

Michael Lehning, Katherine Colby Leonard, Ernesto Trujillo Gomez

Snow distribution over sea ice is an important control on sea ice physical and biological processes. We combine measurements of the atmospheric boundary layer and blowing snow on an Antarctic sea ice floe with terrestrial laser scanning to characterize a t ...

Snow Avalanches.

Christophe Ancey

Avalanches have long been a natural threat to humans in mountainous areas. At the end of the Middle Ages, the population in Europe experienced significant growth, leading to an intensive exploitation of upper valleys. At almost the same time, Europe’s clim ...

Influence of Initial Snowpack Properties on Runoff Formation during Rain-on-Snow Events

Michael Lehning, Nander Wever, Sebastian Würzer, Tobias Jonas

Rain-on-snow (ROS) events have caused severe floods inmountainous areas in the recent past. Because of the complex interactions of physical processes, it is still difficult to accurately predict the effect of snow cover on runoff formation for an upcoming ...

Mountain Snow Distribution and how it may Change in the Future

Michael Lehning, Wolf Hendrik Huwald

The spatial distribution of snow in the mountains is highly heterogeneous, and processes behind this heterogeneity are not yet understood quantitatively. Based on (i) increasing accuracy and spatial coverage of remotely sensed snow depth maps, which have b ...

Decoupling of mass flux and turbulent wind fluctuations in drifting snow

Michael Lehning, Enrico Paterna, Philip Crivelli

The wind-driven redistribution of snow has a significant impact on the climate and mass balance of polar and mountainous regions. Locally, it shapes the snow surface, producing dunes and sastrugi. Sediment transport has been mainly represented as a functio ...

Change in snow distribution patterns over an Antarctic ice floe following a snow storm event

Michael Lehning, Katherine Colby Leonard, Ernesto Trujillo Gomez

Sea ice, snow and atmosphere interactions are major drivers of the spatial distribution of snow over sea ice in polar regions. Here, we quantify changes caused by a snow storm in the spatial distribution of snow over an Antarctic ice floe at resolutions of ...

Wind-driven snow distribution patterns over an Antarctic ice floe

Michael Lehning, Katherine Colby Leonard, Ernesto Trujillo Gomez

Sea ice, snow and atmosphere interactions are major drivers of the spatial distribution of snow over sea ice in polar regions. Here, we combine measurements of the wind flow, atmospheric conditions and blowing snow at two locations on an Antarctic sea ice ...
