| Zusammenfassung |
The effect of viscosity, non linearities,
incident wave period and realistic eastern coastline geometry on energy fluxes
are investigated using a shallow water model with a spatial resolution of 1/4
degree in both meridional and zonal directions. Equatorial and mid-latitude
responses are considered. It is found that (1) the influence of the coastline
geometry and the incident wave period is more important for the westward energy
flux than for the poleward flux, and (2) the effect of the inclination of the
eastern ocean boundary on the poleward energy flux, for the Pacific and Atlantic
Oceans, decline as the period of the incident wave increases. Furthermore, the
model simulations suggest that the poleward energy fluxes from meridional
boundaries give plausible results for motions of seasonal and annual periods.
For comparatively shorter periods, a realistic coastline geometry has to be
included for more accurate results. It is recommended that any numerical model
involving the reflection of baroclinic Rossby waves (of intraseasonal, seasonal
or annual periods) on the eastern Pacific or Atlantic Oceans, should consider
the effect of the coastline geometry in order to improve the accuracy of the
results.
Key words. Oceanography: general (climate and
interannual variability; equatorial oceanography). Oceanography: physical
(eastern boundary currents). |
