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.
