Abstract
To identify new effects in the behavior of localized finite-amplitude eddies, it is convenient to use initial conditions, corresponding to steady-state solitons (Rossby solitons), for the quasigeostrophic potential vorticity (QPV) equation. Then any deviation from the steady-state motion of the eddies will be a consequence of additional effects not taken into account in the QPV equation. Even when the additional nonlinearity is small but acts over a long time period, it will lead to considerable deviations from the soliton solution, and it will not be possible to neglect its effect. In the paper a study is made of the evolution of Rossby solitons with correction for finite-amplitude effects. The time intervals over which the soliton theory remains valid are estimated.
