Risques et impacts environnementaux des retenues d’altitude pour la production de neige de culture dans un contexte de changement climatique

open access: yesRevue de Géographie Alpine, 2011
Mountain reservoirs are hydraulic structures implanted in recreational mountain resorts designed to provide a water reserve mainly used for the production of artificial snow. Their implantation in high-altitude zones makes them highly specific reservoirs

Assessing the Sustainability of Ski Fields in Southern Japan under Global Warming

open access: yesAdvances in Meteorology, 2018
This is the first study in assessing the impact of climate change on Japanese ski fields with ensemble dynamical downscaling simulations. We target three ski fields in Ehime Prefecture, a southern border area for skiing in Japan.

Modeling Wet-Snow Shedding from Current-Carrying Conductors [PDF]

open access: yes
The initiation of wet-snow shedding from currentcarrying conductors was studied experimentally and theoretically. A suspended cable with cylindrical snow accretion was considered, and some of the snow properties at the end of sleeve were measured and ...

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]

open access: yes, 2016
Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

MODIS Fractional Snow Cover Mapping Using Machine Learning Technology in a Mountainous Area

open access: yesRemote Sensing, 2020
To improve the poor accuracy of the MODIS (Moderate Resolution Imaging Spectroradiometer) daily fractional snow cover product over the complex terrain of the Tibetan Plateau (RMSE = 0.30), unmanned aerial vehicle and machine learning technologies are ...

SNOWMIP2: An evaluation of forest snow process simulation [PDF]

open access: yes, 2009
The Northern Hemisphere has large areas that are forested and seasonally snow covered. Compared with open areas, forest canopies strongly influence interactions between the atmosphere and snow on the ground by sheltering the snow from wind and solar ...

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming

open access: yesAdvanced Science, EarlyView.
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Micrometeorological processes driving snow ablation in an Alpine catchment [PDF]

open access: yes, 2011
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.
