Purpose. The study is aimed at assessing the impact of choice of parameterizing the turbulent heat transfer at the ocean - atmosphere boundary upon the basic characteristics of ice regime in the Taganrog Bay apex. Methods and Results. Thermal seasonal dynamics of the snow-ice cover thickness was studied using the non-stationary thermodynamic model of sea ice. The algorithm for defining the turbulent fluxes of momentum, sensible and latent heat in the sea ice regional model is based on the Monin - Obukhov similarity theory. The numerical experiments were performed for the winter seasons of 2007-2008 and 2 017-2018, the meteorological conditions of which differed significantly. The transfer coefficients were determined both as the constant values, and as those depending on the atmosphere stratification and the aerodynamic roughness of underlying surface. Implementing stable stratification implied application of three different expressions for determining the stability functions...
