MARC recordAnalysis and modeling of melt-water refreezing in dry snow / W. Tad Pfeffer, Tissa H. Illangasekare, Mark F. Meier.
| Title: | Analysis and modeling of melt-water refreezing in dry snow / W. Tad Pfeffer, Tissa H. Illangasekare, Mark F. Meier. |
| Author(s): | Pfeffer, W. Tad. Illangasekare, Tissa H. Meier, Mark F. |
| Date: | 1990. |
| In: | Journal of Glaciology. (1990.), Vol. 36(123) (1990) |
| Abstract: | Intended to provide physical basis for estimating rate of freezing of liquid water introduced into cold porous matrix. Dynamic zone of thermal disequilibrium is described which separates wet snow at 0°C from dry sub-freezing snow. Zone may be eliminated by thermal equilibrium through freezing, but is sustained and propagated into sub-freezing snow by water flow from wet snow. Width of dynamic zone is controlled by rate of water inflow, and by rate of freezing of water onto sub-freezing ice grains, which, in turn, is controlled by ice/water geometry. Equilibrium times and freeze-on mass fluxes are calculated for various general conditions. |
