This study provide relatively simple climatological models for determining the incidence of frost days (minimum daily temperature 0 C), ice days (maximum daily temperature 0 C) and freeze-thaw days (minimum daily temperature 0 C), maximum daily temperature 0 C) throughout Iceland, Greenland, Alaska, and E. Siberia. Both area and station models yield estimates of the frequency of diurnal freeze-thaw cycles per month or year. The various models demonstrate the relationships between daily freezing conditions and the different temperature regimes. The results should improve understanding of periglacial activity and provide a means of predicting possible climatic effects on the construction of buildings, roads and airport runways. (Author)
