Internal Tides and Baroclinicity in the Southern Weddell Sea. Part I: Model Description and Comparison of Model Results to Observations

Internal tides and baroclinicity in the southern Weddell Sea 1. Model description

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 topogr...

Internal Tides and Baroclinicity in the Southern Weddell Sea. Part II: Effects of the Critical Latitude and Stratification

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 ...

Modelling tides in the southern Weddell Sea: updated model with new bathymetry from ROPEX

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...

Enhanced Predictions of Tides and Surges through Data Assimilation (TECHNICAL NOTE)

The regional waters in Singapore Strait are characterized by complex hydrodynamic phenomena as a result of the combined effect of three large water bodies viz. the South China Sea, the Andaman Sea, and the Java Sea. This leads to anomalies in water levels and generates residual currents. Numerical hydrodynamic models are generally used for predicting water levels in the ocean and seas. But thei...
