A seasonal snowpack model forced with dynamically downscaled forcing data resolves hydrologically relevant accumulation patterns
Michael Lehning, Tobias Jonas, Dylan Stewart Reynolds
The Mountain snowpack stores months of winter precipitation at high elevations, supplying snowmelt to lowland areas in drier seasons for agriculture and human consumption worldwide. Accurate seasonal predictions of the snowpack are thus of great importance ...
Frontiers Media Sa2024Good 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 ...
EPFL2024Risk assessment of waterborne virus in Lake Geneva: the present and the future
The presence of waterborne enteric viruses in lake recreational water sites is not desired, as they may have a negative impact on human health. However, their concentrations, fate and transport in lakes remain poor understood. To date, the health risks pos ...
2023A novel methodology to identify and quantify deepwater-renewal processes during winter cooling in a large, deep lake (Lake Geneva)
David Andrew Barry, Ulrich Lemmin, Naifu Peng, François Mettra, Rafael Sebastian Reiss
We propose a novel methodology – heat budget decomposition – to identify and quantify different deepwater-renewal processes during a very cold spell in 2012 in a large, deep lake (Lake Geneva, 309-m depth). Combined with field observations and numerical mo ...
2023Snow Loss Into Leads in Arctic Sea Ice: Minimal in Typical Wintertime Conditions, but High During a Warm and Windy Snowfall Event
Julia Schmale, Marc Schneebeli Zeugin, Markus Frey
The amount of snow on Arctic sea ice impacts the ice mass budget. Wind redistribution of snow into open water in leads is hypothesized to cause significant wintertime snow loss. However, there are no direct measurements of snow loss into Arctic leads. We m ...
2023Analyzing the effects of snow-atmosphere interactions on snow surface dynamics based on automated 3D laser scanning data
The snow surface morphology is shaped throughout a winter season by atmospheric conditions, like precipitation, wind, solar irradiance, air temperature or relative humidity. Changes in morphology affect the snow surface roughness which influences the turbu ...
2022Climate Change Impacts on Groundwater Recharge in Cold and Humid Climates: Controlling Processes and Thresholds
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 ...
2022Precipitation fate and transport in a Mediterranean catchment through models calibrated on plant and stream water isotope data
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 ...
