Analyzing the sensitivity of a blowing snow model (SnowPappus) to precipitation forcing, blowing snow, and spatial resolution

Autor: A. Haddjeri, M. Baron, M. Lafaysse, L. Le Toumelin, C. Deschamps-Berger, V. Vionnet, S. Gascoin, M. Vernay, M. Dumont

Publikováno v: The Cryosphere, Vol 18, Pp 3081-3116 (2024)

Accurate snow cover modeling is a high-stakes issue for mountain regions. Alpine snow evolution and spatial variability result from a multitude of complex processes including interactions between wind and snow. The SnowPappus blowing snow model was d

Spatial variability of Saharan dust deposition revealed through a citizen science campaign

Publikováno v: Earth System Science Data, Vol 15, Pp 3075-3094 (2023)

Saharan dust outbreaks have profound effects on ecosystems, climate, human health, and the cryosphere in Europe. However, the spatial deposition pattern of Saharan dust is poorly known due to a sparse network of ground measurements. Following the ext

The S2M meteorological and snow cover reanalysis over the French mountainous areas: description and evaluation (1958–2021)

Autor: M. Vernay, M. Lafaysse, D. Monteiro, P. Hagenmuller, R. Nheili, R. Samacoïts, D. Verfaillie, S. Morin

Publikováno v: Earth System Science Data, Vol 14, Pp 1707-1733 (2022)

This work introduces the S2M (SAFRAN–SURFEX/ISBA–Crocus–MEPRA) meteorological and snow cover reanalysis in the French Alps, Pyrenees and Corsica, spanning the time period from 1958 to 2021. The simulations are made over elementary areas, referr

Propagating information from snow observations with CrocO ensemble data assimilation system: a 10-years case study over a snow depth observation network

Autor: B. Cluzet, M. Lafaysse, C. Deschamps-Berger, M. Vernay, M. Dumont

Publikováno v: The Cryosphere, Vol 16, Pp 1281-1298 (2022)

The mountainous snow cover is highly variable at all temporal and spatial scales. Snowpack models only imperfectly represent this variability, because of uncertain meteorological inputs, physical parameterizations, and unresolved terrain features. In

Statistical post-processing of ensemble forecasts of the height of new snow

Autor: J.-P. Nousu, M. Lafaysse, M. Vernay, J. Bellier, G. Evin, B. Joly

Publikováno v: Nonlinear Processes in Geophysics, Vol 26, Pp 339-357 (2019)

Forecasting the height of new snow (HN) is crucial for avalanche hazard forecasting, road viability, ski resort management and tourism attractiveness. Météo-France operates the PEARP-S2M probabilistic forecasting system, including 35 members of the

Winter tourism under climate change in the Pyrenees and the French Alps: relevance of snowmaking as a technical adaptation

Autor: P. Spandre, H. François, D. Verfaillie, M. Pons, M. Vernay, M. Lafaysse, E. George, S. Morin

Publikováno v: The Cryosphere, Vol 13, Pp 1325-1347 (2019)

Climate change is increasingly regarded as a threat for winter tourism due to the combined effect of decreasing natural snow amounts and decreasing suitable periods for snowmaking. The present work investigated the snow reliability of 175 ski resorts
