| Zusammenfassung |
| The transformation of nonlinear long internal waves in a two-layer fluid is
studied in the Boussinesq and rigid-lid approximation. Explicit analytic
formulation of the evolution equation in terms of the Riemann invariants
allows us to obtain analytical results characterizing strongly nonlinear
wave steepening, including the spectral evolution. Effects manifesting the
action of high nonlinear corrections of the model are highlighted. It is
shown, in particular, that the breaking points on the wave profile may shift
from the zero-crossing level. The wave steepening happens in a different way
if the density jump is placed near the middle of the water bulk: then the
wave deformation is almost symmetrical and two phases appear where the wave
breaks. |
