15 صفحه اولA dry snow pack model
A dry snow pack is viewed as an interacting mixture of rigid ice grains and air occupying the pore space in the matrix. The three-dimensional mass, momentum and energy balances are formulated within the framework of interacting continua theory. The assumption of a common ice and air temperature is made to reflect the very slow relative motion between the air and ice. Focusing on a one-dimension...

متن کاملEffect of Snow Density Irregularities on Radar Backscatter from a Layered Dry Snow Pack
The contribution of electromagnetic wave scattering on density irregularities in the volume component of radar backscatter was analyzed for a thick snow pack containing internal hoar/ice layers. To evaluate the effect of this scattering, Density Deviation Factor (DDF), a statistical parameter, was introduced into the backscattering coefficient using the “slice” approach. DDF is proportional to ...
