Abstract 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.
