Application programs for simulation the temperature regime of the active layer of the vicinity of the Belarusian Antarctic station
Abstract
This paper introduces two applied tools designed to simulate the thermal regime of the active layer in the vicinity of the Belarusian Antarctic station. The first program focuses on temperature dynamics over horizontal surfaces, while the second incorporates the effects of surface inclination and its specific features. The horizontal-surface model employs a three-dimension orthogonal grid, whereas the slope-oriented model is based on a three-dimensional non- orthogonal mesh. Both approaches account for the temperature-dependent phase composition of water and the thermophysical properties of the upper soil layer. Boundary conditions are formulated using meteorological inputs, including air temperature, wind speed, and solar radiation. In the slope model, particular attention is given to the influence of surface angle on the diurnal variation of incoming solar flux.
The developed tools were tested against benchmark models and validated through comparison with field monitoring data collected at control sites. The numerical simulations demonstrated satisfactory agreement with the observed temperature profiles, confirming the reliability of the proposed methodology.
