EVALUATION OF THE SENSITIVITY OF THE SURFACE HEAT EXCHANGE CALCULATION MODEL TO THE ATMOSPHERE FOR THE AREA OF THE SHESTAKOVKA RIVER BASIN, CENTRAL YAKUTIA

This article analyzes the variability of modeling results depending on various initial data used to assess the influence of meteorological parameters on the conditions of heat exchange between the atmosphere and the soil in the Yakutia region. The contribution of meteorological variables such as air temperature, surface temperature, atmospheric transparency, total cloud cover and albedo of the underlying surface was assessed. The thermophysical properties of the soil remained unchanged, while other parameters were varied. The input data were used to simulate the process of heat transfer between the atmosphere and the ground, and the obtained values of the heat flux were used in modeling the process of heat and mass transfer. The results of the analysis showed that a change in the transparency coefficient leads to significant variability in the simulation results.
