| Zusammenfassung |
| Two-dimensional vortex pairs are
frequently observed in geophysical conditions, for example, in a shelf
zone of the ocean near river mouths. The main aims of the work are to
estimate the space scales of such vortex structures, to analyze possible
scenarios of vortex pair motion and to give the qualitative classification
of their trajectories. We discuss some features of the motion of strong
localized vorticity concentrations in a given flow in the presence of
boundaries. The analyses are made in the framework of a 2D point
vortex mo-del with an open polygonal boundary. Estimations are made for
the characteristic parameters of dipole vortex structures emitted from
river mouths into the open ocean. |
