Аннотация: Temperature distributions in snow, measured in the laboratory and the field are always used as a basis for the calculation of snow-heat conduction and water-vapor-diffusion characteristics. According to recently obtained experimental data temperature distributions are not linear even under steady conditions and thus do not fit into present theories of the simultaneous heat and mass-transfer mechanisms. The temperature distributions are related to the heat-transfer processes in a much more complicated way than is presently accepted. They must be the result of latent heat release in snow recrystallization that is superimposed on the balance between the evaporation and condensation processes, regulated by the specific surface area of the ice matrix, snow structure, and potentiality of the porous space for water-vapor transfer.
