Classification of Weather Stations in Switzerland
Understanding the local terrain features is crucial when it comes to interpretation of weather observations (e. g. comparison of wind speeds during a storm event or validation of temperature extrema). The landform classification algorithm described above is applied to the set of automated weather stations run owned by MeteoSwiss. A simple classification by altitude and local landform (figure 2) provides a good overview of station characteristics. Detailed maps allow for a better understanding of local weather/climate processes. The weather station of Buffalora (Grisons, Switzerland) at an altitude of 1970 m AMSL frequently reports the lowest daily minimum temperatures in the whole observation network. Figure 3 exhibits the terrain pattern in this Alpine high-valley. There is a distinct ground depression near the station which permits the formation of nocturnal cold air pool.
