metadata.value: In this paper, dynamic characteristics of mesoscale vortices in the ocean are considered using the
  theory of columnar vortices with a helical structure. The radial profile of the relative vorticity is approximated
  with the Q-distribution. Expressions connecting the distributions of the horizontal and
  vertical velocity components in this type of vortices are obtained. The limitations for the applicability
  of the analytical solution are derived. The advantages and disadvantages of this model are shown in
  comparison with the radial distributions of the corresponding parameters in Scully and in Rayleigh
  vortices. In particular, it is shown that the Q-distribution can, in some sense, be considered as a compromise
  solution between the two distributions above. The theory of columnar Q-vortices with helical
  structure is applied to the permanently existing anticyclonic Lofoten vortex of the Norwegian Sea. The
  mean radial distributions of various dynamics characteristics of the Lofoten vortex are obtained using
  simulations with the regional hydrodynamic model MIT. The reasons for formation of the observed
  vertical velocity structure are analyzed. It is shown that, in contrast to atmospheric synoptic structures,
  divergence of Ekman fluxes in the bottom layer affects only the lower part of the vortex. In the upper
  ocean, ascending vertical motion is observed in the Lofoten vortex. It is assumed that horizontal dispersion
  of vortex energy, the most intense in the surface layer, plays an essential role in the formation
  of the field of vertical velocities in the upper part of its core. Refs 36. Figs 3.
