Model simulations of the modulating effect of the snow cover in a rain-on-snow event

Michael Lehning, Nander Wever, Charles Fierz, Tobias Jonas

In October 2011, the Swiss Alps underwent a marked rain-on-snow (ROS) event when a large snowfall on 8 and 9 October was followed by intense rain on 10 October. This resulted in severe flooding in some parts of Switzerland. Model simulations were carried o ...

Do peatlands hibernate?

Alexandre Buttler, Vincent Eric Jules Jassey, Constant Signarbieux, Robert Thomas Edmund Mills

Winter seasonality with low amounts of incoming radiation, frost and snow cover characterize large areas at mid- and high latitudes, especially in the arctic and in mountain ranges. Because of these adverse conditions, it is often assumed that ecosystem pr ...

Simulating melt crust and ice lens formation in a physically based snowpack model

Michael Lehning, Nander Wever, Charles Fierz

Water flow in a natural snow cover is generally a complex process because of the strongly stratified and changing structure of the snowpack. Important differences in, for example, density and grain size between layers cause sometimes very sharp transitions ...

SNOWPACK: where do we stand today?

Michael Lehning, Nander Wever, Mathias Thierry Pierre Bavay, Charles Fierz

The Swiss snow-cover model SNOWPACK is presently used in many applications from snow sports and engineering to climate change assessment but also for avalanche warning. The core routines are packed in a library that also serves as the basic module for the ...

Separating local topography from snow effects on momentum roughness in mountain regions

Michael Lehning, Marc Parlange, Gabriel George Katul, Marc Calaf Bracons, Marc Diebold

Parametrization of momentum surface roughness length in mountainous regions continues to be an active research topic given its application to improved weather forecasting and sub-grid scale representation of mountainous regions in climate models. A field c ...

Studies of the spatial variability of alpine snowfall using an X-band polarimetric radar

Michael Lehning, Alexis Berne, Danny Eddy Scipion Castillo

A mobile polarimetric X-band radar (MXPol) was deployed in Davos, Switzerland in collaboration with SLF (WSL - Institute for Snow and Avalanche Research). MXPol was installed in the beginning of October 2009 and collected valuable and continuous informatio ...

Micrometeorological processes driving snow ablation in an Alpine catchment

Michael Lehning, Mathias Thierry Pierre Bavay, Thomas Grünewald

Mountain snow covers typically become patchy over the course of a melting season. The snow pattern during melt is mainly governed by the end of winter snow depth distribution and the local energy balance. The objective of this study is to investigate micro ...
