| Zusammenfassung |
| Strongly nonlinear internal waves in a layer with arbitrary stratification
are considered in the hydrostatic approximation. It is shown that "simple
waves" having a variable vertical structure can emerge from a wide class of
initial conditions. The equations describing such waves have been obtained
using the isopycnal coordinate as a variable. Emergence of simple waves from
an initial Gaussian impulse is numerically investigated for different
density profiles, from two- and three-layer structure to the continuous one. Besides the
first mode, examples of second- and third-mode simple waves are given. |
