Permafrost environment of the Daisetsu Mountains, Hokkaido, Japan
The distribution of permafrost in the Daisetsu Mountains is discussed on the basis of freezing and thawing indices and the pattern of winter snow distribution. Mean annual air temperature at an altitude of 2000 m a.s.l. is estimated to be −3.6 °C in normal years. Alpine permafrost is distributed mai...

The distribution of permafrost in the Daisetsu Mountains is discussed on the basis of freezing and thawing indices and the pattern of winter snow distribution.

The windward bare ground extends to summit areas, where most snow is removed from the ground surface by strong prevailing wind. The lower limit of permafrost is considered to be about 1650 m a.s.l.
