This article continues the authors' research on changes in the Väisälä-Brunt frequency caused by mesoscale vortices of different polarities. If the first part discussed theoretical conclusions, the second one gives an interpretation of these results based on field data. The research area is the Lofoten Basin in the Norwegian Sea. For the analysis, we use data from the ocean reanalysis GLORYS12V1 for June 10, 2010. Two vortices are considered: a quasi-permanent anticyclone is the Lofoten Vortex, located in the center of the basin, and a cyclone located southeast of the Lofoten Vortex. Mathematical formulas obtained in Part 1 are checked, the characteristics of vortices are calculated, profiles and vertical sections of potential vorticity and the Väisälä-Brunt frequency are studied. Based on the joint analysis of field and theoretical material, the properties of the considered vortices are indirectly estimated, which cannot be measured directly and cannot be obtained in models.
