Abstract

Marine eddies observed in radar, optical and radiometric panoramas of the sea surface play an important role in the processes of ocean local and global mixing, suspended and organic matter redistribution, propagation of pollutant waters, biological processes et al. Meanwhile, in-situ investigations of the statistical characteristics of generating vortices in the water areas are difficult to conduct. The widespread method of marine eddies investigation is based on the remote sensing data. However, the relation between the characteristics of spiral structures and the marine eddies which lead to their manifestation is poorly studied. In order to investigate this relation, we apply the well-known MCC-method. Investigation of the horizontal fields related to the manifestation of spiral structures revealed new peculiarities which can be described analytically. The analytical model describes the velocity field composed of a marine eddy and a homogeneous current, the results are confirmed by the velocity fields obtained using satellite data, the new features of upper ocean currents associated with marine eddies are discussed. The described approach allows to retrieve inner structure of the genuine velocity field related to marine eddy.
