Abstract
Using the data of observations of the ice cover in theWeddell Sea near the Antarctic coast in a period of the polar night, we carried out numerical experiments with the one-dimensional model of the atmospheric boundary layer. The processes of background advective heat and moisture transport, the catabatic component of motions and vertical turbulent snow transport under the conditions of blowing snow are parameterized in the model. It is shown that the results on the computation of temperature and specific humidity are in good agreement with the corresponding observational data when we take into account the joint efect of baroclinity and relief. It is also established that the consideration of the snow turbulent diffusion process leads to the higher quality of reproducing the wind velocity and friction stress in the atmospheric surface layer.
