    An interacting continua framework is adopted to model a dry snowpack, which is viewed as a three-constituent mixture composed of an ice- matrix whose pore space is occupied by water vapour and dry air. We focus on the response of a one-dimensional vertical snowpack to changes in pressure and temperature at its surface. The time-scale of the surface forcing is assumed to be much longer than the time-scale for thermal transfers and phase change to take place. Illustrations for the case of a sinusoidal annual temperature gradient imposed at the surface are presented. -from Authors
