| Zusammenfassung |
| A numerical model is used to investigate the resonances of the Gulf of
Carpentaria and the Arafura Sea, and the additional insights that come from
extending the analysis into the complex angular velocity plane. When the
model is forced at the shelf edge with physically realistic real values of
the angular velocity, the response functions at points within the region show
maxima and other behaviour which imply that resonances are involved but
provide little additional information. The study is then extended to complex
angular velocities, and the results then show a clear pattern of gravity wave
and Rossby wave like resonances. The properties of the resonances are
investigated and used to reinterpret the response at real values of angular
velocity. It is found that in some regions the response is dominated by modes
trapped between the shelf edge and the coast or between opposing coastlines.
In other regions the resonances show cooperative behaviour, possibly
indicating the importance of other physical processes. |
