Internal tides and baroclinicity in the southern Weddell Sea 1. Model description
نویسنده
چکیده
Near the continental shelf break in the southern Weddell Sea, Warm Deep Water and Western Shelf Water meet. Mixing mechanisms, such as internal tides, have the potential to mix these water masses and form Antarctic Bottom Water. A modified version of the Princeton Ocean Model was utilized to investigate the internal tidal fields generated by the interaction of the M2 barotropic tide with topography for transects across the continental shelf and slope in the southern Weddell Sea. Internal tides were generated over the upper continental slope as predicted by linear internal wave theory. Although the essentially two-dimensional domain resulted in differences between the model elevations and the observations exceeding the observational uncertainties, the cross-slope velocities agreed well with differences less than the uncertainties for 78% of the existing observations.

In the southern Weddell Sea, several water masses with the capability to form Antarctic Bottom Water (AABW) meet near the continental shelf break. The internal tidal field over the continental shelf break here is of interest due to its potential to mix these waters and form AABW. A modified version of the Princeton Ocean Model (POM) was utilized to investigate the internal tidal fields generate...

Internal tides and baroclinicity in the Southern Weddell Sea 2. Effects of the critical latitude and stratification
Tidal dynamics affect Antarctic Bottom Water and Ice Shelf Water production in the southern Weddell Sea and the general circulation and mixing. In this region, tidal dynamics were found to be extremely sensitive both to the proximity of the continental shelf-slope break to the critical latitude ? crit and to the existence of a shelf break front. If the continental slope was not in the vicinity ...

A significant fraction of the total oceanic kinetic energy in the southern and western Weddell Sea is supplied by tidal currents [Robertson et al., 1998: denoted “RPE-98”]. The region of strong tides includes the ocean cavity under the Filchner-Ronne Ice Shelves (FRIS), and the adjacent broad southern continental shelf and upper slope. The spatial distribution of tidal energy was estimated usin...
متن کاملA Correction to the Baroclinic Pressure Gradient Term in the Princeton Ocean Model
An error in the calculation of the baroclinic pressure gradient term in the Princeton Ocean Model (POM) was identified while modeling the M2 tidal currents near its critical latitude in the southern Weddell Sea. The error arises from the present calculation of density, which involves the subtraction of a background density profile from the density field calculated at each internal time step. Th...
