An empirical model to calculate snow depth from daily snow water equivalent: SWE2HS 1.0

Many methods exist to model snow densification in order to calculate the depth of a single snow layer or the depth of the total snow cover from its mass. Most of these densification models need to be tightly integrated with an accumulation and melt model a ...

Towards a fully physical representation of snow on Arctic sea ice using a 3D snow-atmosphere model

Michael Lehning, Adrien Michel, Mahdi Jafari, Océane Hames, Nander Wever, Marc Schneebeli Zeugin, David Nicholas Wagner

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 ...

The Effect of Wind on the Surface Snow Microstructure – Experimental Insights

Sonja Wahl, Benjamin Andreas Walter

Snow precipitation frequently occurs under moderate to strong wind conditions, resulting in drifting and blowing snow. Processes like particle fragmentation and airborne metamorphism during snow transport result in microstructural modifications of the ulti ...

Modeling the small-scale deposition of snow onto structured Arctic sea ice during a MOSAiC storm using snowBedFoam 1.0.

Michael Lehning, Mahdi Jafari, Océane Hames, Marc Schneebeli Zeugin, David Nicholas Wagner

The remoteness and extreme conditions of the Arctic make it a very difficult environment to investigate. In these polar regions covered by sea ice, the wind is relatively strong due to the absence of obstructions and redistributes a large part of the depos ...

Wind-tunnel experimental studies of the spatial snow distribution over grass and bush surfaces

Guang Li

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 ...

Fluorescent aerosols in the Arctic: Seasonality and sources

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Margarida Teles Nogueira Rolo

Aerosol-cloud interactions play an important role in regulating the Arctic climate. However, cloud formation processes in the Arctic remain poorly understood and information on aerosol properties in this environment are insufficient, especially during pola ...

Parameterizing snow saltation: the exponential decay of the mass flux profile and its relation to the saltation dynamics

Varun Sharma, Michael Lehning, Daniela Brito Melo, Armin Sigmund

Drifting snow events lead to snow redistribution and enhance snow sublimation. Taking into account the importance of snow sublimation to the correct prediction of the surface mass balance, a general consensus has emerged within the scientific community on ...

Climate Change Impacts on Groundwater Recharge in Cold and Humid Climates: Controlling Processes and Thresholds

Emmanuel Qays Dubois

Long-term changes in precipitation and temperature indirectly impact aquifers through groundwater recharge (GWR). Although estimates of future GWR are needed for water resource management, they are uncertain in cold and humid climates due to the wide range ...

Precipitation fate and transport in a Mediterranean catchment through models calibrated on plant and stream water isotope data

Paolo Benettin

To predict hydrologic responses to inputs and perturbations, it is important to understand how precipitation is stored in catchments, released back to the atmosphere via evapotranspiration (ET), or transported to aquifers and streams. We investigated this ...

High-speed imaging of snow saltation: wind tunnel experiments using natural snow

Michael Lehning, Daniela Brito Melo, Benjamin Andreas Walter

Drifting snow is a multi-scale process. It is composed of particles rolling and sliding along the surface, particles in saltation following short ballistic trajectories in the first 10 cm above the surface and particles in suspension at higher regions of t ...
