Mesoscale subduction at the Antarctic Polar Front driven by baroclinic instability

A study of mesoscale subduction at the Antarctic Polar Front is conducted using hydrographic data from a high-resolution, quasi-synoptic survey of the front. The geostrophic velocity and isopycnal potential vorticity fields are computed, and the ageostrophic flow is diagnosed from the semigeostrophi...

Zusammenfassung:A study of mesoscale subduction at the Antarctic Polar Front is conducted using hydrographic data from a high-resolution, quasi-synoptic survey of the front. The geostrophic velocity and isopycnal potential vorticity fields are computed, and the ageostrophic flow is diagnosed from the semigeostrophic omega equation.
