Abstract

Based on the analysis of a sequence of optical (MODIS-Aqua / Terra, AVHRR NOAA-18, VIIRS-SNPP, TIRS and OLI Landsat-8, ETM + Landsat-7) and radar (Sentinel-1A, Radarsat-2) satellite images, the evolution of mesoscale anticyclonic vortex with a diameter of about 35 km and associated cyclones (two to four) at its periphery was traced for more than a month and a half (from May 15 to July 7, 2015) in the South-Eastern Baltic. Within about a month the position of the anticyclone varied little (center – at about 54° 55’ N, 19°15’ E), but in the interval from June 22 to July 1 the vortex dipole formed by this anticyclone and the cyclone at its northern periphery with a diameter comparable with the diameter of the anticyclone moved eastward with an average speed of about 4 km/day. It is assumed that such movement of this quasisymmetric vortex dipole was due to its location to the north of the Gdansk Bay and the property of a dipole (mushroom-like current) to move in the direction of its jet part under wind forcing (in this case, with the strengthening of the westerly wind).
