Submesoscale processes are highly energetic ocean currents, eddies and filaments in the ocean surface mixed layer, with horizontal scales of 0.1 to 10 km, characterized by order-one Rossby numbers. These processes effectively bridge the gap between large-scale mesoscale eddies and small-scale turbulence, playing crucial roles in ocean circulation, air-sea interaction, and marine ecosystem structures. In this study, using a high-resolution (800 m) ocean and sea ice coupled model, we investigate the seasonal evolution of the submesoscale processes along the Norwegian coast.
