Abstract : A study of heat fluxes in soil is of interest because the quantity and direction of these fluxes, in a final analysis, determines the fluctuation of the boundary between the active layer (or unfrozen soil) and the frozen soil. In the present article, the results of the author's experimental investigations which determine certain quantitative values of the thermal coefficients and heat fluxes in frozen soil are presented. Heat fluxes in the soil were calculated directly by proceeding from values of thermal properties of the medium and of the distribution of its temperature with respect to depth and to time. Thermal conditions of the following media were investigated: of soil covered by snow, of (bare) soil without snow cover, of the snow cover itself. Systematic measurements of soil humidity (moisture) and snow densities were made. (Author)
