On convection and the formation of subantarctic mode water in the Fine Resolution Antarctic Model - FRAM
We investigate the formation of Subantarctic Mode Water (SAMW) in the Fine Resolution Antarctic Model (FRAM). FRAM velocity fields are applied to advect an ideal tracer in an off-line diffusion and advection model of the Southern Ocean, and the results from two computational experiments are reported...

We investigate the formation of Subantarctic Mode Water (SAMW) in the Fine Resolution Antarctic Model (FRAM).
