Methodology
Indicator metadata
- Definition
- A climate indicator reflecting the average frequency of solid precipitation (snow) in the winter period (December, January, February) over a moving 10-year time window. It is used to monitor changes in the pattern of winter precipitation, to assess the risks of low snowfall (which affects the formation of river runoff) and to forecast avalanche danger in mountain areas.
- Calculation method
- The calculation is performed in two stages: 1. For each individual year, the total number of days on which snowfall was recorded (regardless of its duration and intensity) is summed over the three winter months: December of the previous year and January and February of the current year. 2. The resulting annual totals for the last 10 years are added up and the result is divided by 10 (the arithmetic mean is calculated). The base calculation window is shifted annually (for example, for the 2026 report the period 2016/17–2025/26 is used). The indicator is calculated annually
