Permafrost occurrence from BTS measurements and climatic parameters in the eastern Swiss Alps
Relations between climatic parameters such as temperature and potential direct solar radiation (PR) and measured bottom temperatures of the snow cover (BTS) as indicator of permafrost occurrence were investigated.

| Summary: | Relations between climatic parameters such as temperature and potential direct solar radiation (PR) and measured bottom temperatures of the snow cover (BTS) as indicator of permafrost occurrence were investigated. No significant correlation exists between mean annual air temperature (MAAT) and BTS. The high correlation found between PR and BTS may help to develop a model for predicting permafrost distribution in mountain areas. This correlation and the low one between MAAT and BTS help to explain the existence of the low‐altitude permafrost in alpine regions. Les relations entre paramètres climatiques, tels que la température de l'air et la radiation solaire (PR) et les températures à la base de la couche nivale (BTS) comme indicateur de pergélisol. Il n'y a pas de corrélation significative entre le température moyenne annuelle de l'air (MAAT) et les BTS. Une bonne corrélation a peu ětre trouvée entre PR et BTS, permettant ainsi le développement d'un modèle pour prédire le pergélisol dans les régions montagneuses. Les relations MAAT‐BTS et PR‐BTS analysées ici peuvent aider à expliquer l'apparition du pergélisol dans les régions peu élevées des Alpes. |
