Village, 715 m
12 fewer days a winter with 30 cm or more than in 1961–1990.Mid-mountain, 1,046 m
27 fewer days a winter with 30 cm or more than in 1961–1990.Modelled from ERA5 weather (Copernicus Climate Change Service), one consistent record for every winter. Checked against measured snow, this model got the direction of change right at 18 of 19 Swiss weather stations and 22 of 25 US snow stations, but overstated its size: a typical loss of 26 days against 17 measured in Switzerland, and 12 against 6 in the US.
