Abstract : The heat transfer processes between a snow cover and its environment were studied and evaluated in order to predict changes in the physical characteristics of the snow cover from standard methorological information. The study was based on micrometeorological and related snow and soil data collected at the Keeweenaw Field Station (Mich.) from 1954-1956. Computations of conductive heat transfer in snow, using the Liljequist method, showed significant correlation with average air temperatures. Average values of the cold content of snow can be estimated from average air temperatures. Average temperature differences through the snow can be estimated from a knowledge of the previous 20-hr average air temperature; snow hardness can be estimated graphically from snow density and depth.
