      A spherical coordinate version of the unstructured grid 3-D FVCOM (finite volume coastal ocean model) has been applied to the Arctic Ocean to simulate tides with a horizontal resolution ranging from 1 km in the near-coastal ...
    • A new mechanism for the generation of quasi-zonal jets in the ocean 

      Wang, Jinbo; Spall, Michael A.; Flierl, Glenn R.; Malanotte-Rizzoli, Paola (American Geophysical Union, 2012-05-16)
      A simple barotropic quasi-geostrophic model is used to demonstrate that instabilities radiated from an unstable eastern boundary current can generate zonal striations in the ocean interior with realistic wavelengths and ...
    • A new parameterization for entrainment in overflows 

      Cenedese, Claudia; Adduce, Claudia (American Meteorological Society, 2010-08)
      Dense overflows entrain surrounding waters at specific locations, for example, sills and constrictions, but also along the descent over the continental slope. The amount of entrainment dictates the final properties of these ...
