Zusammenfassung |
The characteristics of highly nonlinear solitary internal waves
(solitons) are calculated within the fully nonlinear numerical model
of the Massachusetts Institute of Technology. The verification and
adaptation of the model is based on the data from laboratory
experiments. The present paper also compares the results of our
calculations with the calculations performed in the framework of the
fully nonlinear Bergen Ocean Model. The comparison of the computed
soliton parameters with the predictions of the weakly nonlinear
theory based on the Gardner equation is given. The occurrence of
reverse flow in the bottom layer directly behind the soliton is
confirmed in the numerical simulations. The trajectories of
Lagrangian particles in the internal soliton on the surface, on the
pycnocline and near the bottom are computed. |
