Average of several regional climate models (EURO-CORDEX). Compare the scenarios with the model reference 1986–2005, not with the yearly values above: models and reanalysis have different errors. Scenarios are not forecasts.
Same numbers as
The data describe a region and a 100 m height band, not individual runs. These resorts lie in the same region at the same mid-mountain band: Bergbahnen Werfenweng, Fageralm, Flachau, Schmittenhöhe Zell am See, Skicircus Saalbach-Hinterglemm Leogang Fieberbrunn.

What the numbers mean
- “Snow” here means at least 30 cm of snow depth in the model (Crocus) — enough to ski on, not just a white field.
- The model works per region (NUTS-3) and 100 m height band, not per piste; north-facing slopes, wind and glaciers are not taken into account.
- The reanalysis ends with the 2013/14 winter. More recent winters are not included.
- “With snowmaking” is the model's typical snowmaking, not the resort's actual equipment.
