Abstract: The paper presents results of analysis of experimental data on activity of snow recrystallization under temperature gradient conditions. In addition to temperature and temperature gradient effects, recently accepted as the main factors influencing the snow recrystallization process, the effects of the water vapor flux and the volumetric mass production, related to the formed in snow heat and mass-fluxes, were estimated. The results suggest that the reported discrepancies between the results of observation and the modeled by presently used empirical construction recrystallization rates can be related to neglected before parameters of the water vapor in the pore space of snow.
