Abstract

This study addresses the impact of variations in the timing and duration of seasonal snow cover on the thermal regime of the active layer and permafrost in the Alaskan Arctic through numerical modelling. Meteorological data from 1995 to 1998 at Barrow, Alaska, were used as baseline inputs. The active layer thickness in 1998 and the ground temperatures at depths of 0.0, 0.5, 1.0, and 2.0 m during September 1997 through August 1998 were simulated. A series of simulation cases was conducted by varying the snowpack onset date in autumn and the disappearance date in spring
