Good enough: Intermediate complexity atmospheric models improve the representation of processes affecting seasonal snow
Snow plays a crucial role in processes regulating ecosystems, the climate, and human development. Mountain snowpack in particular has great relevance for downstream communities. Knowledge about the distribution and properties of the snowpack thus help in p ...
EPFL2024Impact 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 ...
2024Constraining Latent and Sensible Heat Fluxes during Drifting and Blowing Snow Events in Antarctica using in–situ Measurements and Large–Eddy Simulations
Varun Sharma, Michael Lehning, Wolf Hendrik Huwald, Jérôme François Sylvain Dujardin, Franziska Gerber, Daniela Brito Melo, Francesco Comola, Armin Sigmund
Reliable predictions of sea level rise require a quantitative understanding of the mass balance of the Antarctic ice sheet. Water vapor exchange between snow and the atmospheric boundary layer may be an important term in the mass balance equation but curre ...
2023A Novel Method to Quantify Near-Surface Boundary-Layer Dynamics at Ultra-High Spatio-Temporal Resolution
Michael Lehning, Tobias Jonas, Dylan Stewart Reynolds, Michael Haugeneder
The lateral transport of heat above abrupt (sub-)metre-scale steps in land surface temperature influences the local surface energy balance. We present a novel experimental method to investigate the stratification and dynamics of the near-surface atmospheri ...
SPRINGER2022Wind-tunnel experimental studies of the spatial snow distribution over grass and bush surfaces
The snow is one of the most important water resources in grassland in northern and western China, while the wind blowing snow due to the strong wind there is a common phenomenon, which can lead to heavy disasters to harm the local animal husbandry and tran ...
SPRINGER2022Introducing CRYOWRF v1.0: Multiscale atmospheric flow simulations with advanced snow cover modelling
Varun Sharma, Franziska Gerber
Accurately simulating snow-cover dynamics and the snow-atmosphere coupling is of major importance for topics as wide-ranging as water resources, natural hazards and climate change impacts with consequences for sea-level rise. We present a new modelling fra ...
2021Simulating airborne 'snow walls' of Antarctica using CRYOWRF v1.0
Varun Sharma, Michael Lehning, Franziska Gerber
When a well-developed, high velocity katabatic flow draining down the ice sheet of Antarctica reaches the coast, it experiences an abrupt and rapid transition due to change in slope resulting in formation of a hydraulic jump. A remarkable manifestation of ...
2021The monitoring and modelling of snow preparation in alpine and cross country ski areas
The report explores the eects of track preparation in alpine and cross country skiing areas. The rapidly evolving state of the art and the high customer demand are pushing the ski resorts to dedicate an increasing part of their budget to the production and ...
