| Zusammenfassung |
| A numerical analysis
is made on the appearance of oceanic internal solitary waves in a
multi-modal setting. This is done for observed profiles of stratification
from the Sulu Sea and the Bay of Biscay, in which thermocline motion is
dominated by the first and third mode, respectively. The results show that
persistent solitary waves occur only in the former case, in accordance
with the observations. In the Bay of Biscay much energy is transferred
from the third mode to lower modes, implying that a uni-modal approach
would not have been appropriate. To elaborate on these results in a
systematic way, a simple model for the stratification is used; an
interpretation is given in terms of regimes of thermocline strength. |
