The thesis is devoted to investigate the mean state and seasonal variability of the water circulation and the large-scale fronts in the Southern Atlantic (SA), using the modern climatic hydrological array, archive data set and satellite observations. Its relation with variability of the wind field is investigated. Shown, that the response of ocean upper layer on the seasonal variations of large-scale wind field displays in change of the system South subtropical anticyclonic gyre (SSbTAG) - South tropical cyclonic gyre (STCG). The weakening of south-east trade-wind in first half-year results in expansion of zonal boundaries of SSbTAG and extension of its area. The STCG area is diminished. The seasonal cycle propagation in the SA currents from west to east is discovered, using satellite altimeter data. The maximal phase lag (6 months) is to be observed in the North Branch of Antarctic Circumpolar current. The climatic temperature and salinity fronts are investigated. Its revealed criteria and seasonal variability regularities are refined. Discovered, that frontal system in the Tropical Atlantic is asymmetric relatively equator. The unknown earlier the South branch of the South Tropical front, the South branch of the South Subequatorial front, Front of North branch of the South Equatorial current are found and investigated. The seasonal variability of the SA water masses is investigated. Shown, that the relationship between seasonal dynamic of the atnicyclonic gyre, fronts and surface water masses areas are appeared as antiphase variability of areas subtropical water masses and their mode modifications. The fronts structure, geostrophic circulation characteristics and thermohaline characteristics of water masses in the western part of Scotia Sea and Bransfield strait are analyzed, using the observation's results, obtained during the Ukraine Antarctic expeditions.
