Modeling Frontal Subduction with ROMS

Frontal subduction of Arctic Water has been observed in the Polar Front
separating Atlantic and Arctic Water in the Nordic Seas. This process
is recreated in an idealized setup with the ROMS model. The experiment
is done in a rather deep periodic channel with an along-channel ridge.
Sensitivity studies are performed to examine the performance of the
model and the robustness of the process with different resolutions and
parameterizations. Emphasis is put on the dependence on the various
vertical mixing schemes provided in ROMS.
