EFFECTIVE THERMAL CONDUCTIVITY OF SNOW AND ITS VARIATIONS
Various empirical relationships of thermal conductivity vs. density and temperature are compared and analyzed in terms of applicability to estimation of the thermal conductivity of snow. The contributions of water vapor diffusion and air convection to the effective thermal conductivity of a snowpack of diff erent temperatures and densities are estimated by mathematical modeling. Experimental estimates of the thermal conductivity of snow are reported for mid-latitude European Russia. The experimental results are compared with those obtained by other authors.
