Abstract A theory for lenses whose geometric and internal deformation radii are comparable is developed. By constraining the lenses to be elliptical, it is possible to treat the nonlinear terms in the hydrodynamic equations in a complete fashion. This means that thes terms are balanced exactly by the local, Coriolis, and hydrostatic head gradient accelerations. Two examples of the dynamical evolution of such a lens are presented. The first considers the motion in the absence of any external flow. The second examines the dynamical response of the lens to large-scale deformation. The principal conclusion of the study is that the inclusion of the nonlinear terms in the dynamical balance induces fluctuations in the internal wave band of the hydrodynamic fields.
