Impact of water vapor diffusion and latent heat on the effective thermal conductivity of snow [PDF]

The Cryosphere, 2021
Heat transport in snowpacks is understood to occur through the two processes of heat conduction and latent heat transport carried by water vapor, which are generally treated as decoupled from one another. This paper investigates the coupling between both

Macroscopic water vapor diffusion is not enhanced in snow [PDF]

The Cryosphere, 2021
Water vapor transport in dry snowpacks plays a significant role for snow metamorphism and the mass and energy balance of snowpacks. The molecular diffusion of water vapor in the interstitial pores is usually considered to be the main or only transport ...
