Аннотация: An experiment on heat and mass transfer in snow under a temperature gradient was carried out in the laboratory. Opposite ends of snow samples were kept at different temperatures for prolonged periods of time. The time to achieve a quasi-steady temperature distribution varied from about 10 hours to about 40 hours depending on the sample length. It was found that quasi-steady temperature distributions were not linear but that the temperature gradient decreased in the direction of heat flow. This result suggests that heat transport cannot be explained as a pure conduction mechanism in snow having uniform thermal conductivity, and that the contributions of water vapor transport and phase change can be important to different degrees in snow.
