Based on ERA5 reanalysis for the period of 1991-2020 and observations during 2011-2020 the basic patterns of multiyear distribution and seasonal variability of wind characteristics in the Antarctic Peninsula region have been revealed. In terms of interannual variability and separate months we have determined correlation relationships between wind field changes and variability of Southern Annular Mode and Amundsen Sea Low. Using the snow depth data we calibrated SWAT hydrological model. Obtained optimal parameters of snow acсumulation/melting have been used for modelling of surface runoff and snow depth changes at the 1°×1° domain in the west of Antarctic Peninsula. By the data at one of the modelled sub-basins near the "Academik Vernadsky" station the most statistically significant dependency between modelled surface runoff and observed surface air temperature has been revealed in monthly time scale. It was also obtained that snow accumulation or melting has the strongest relationship with the solid precipitation sums. There have been confirmed that modelled daily surface runoff by the means of SWAT model well correspond with results of previous research for the case study of heavy precipitation. Number of determined statistical characteristics of mesoclimate partly represent connection between hydrological features of land surface and state of atmospheric surface layer.
