Arctic Ocean Modeling: The Consistent Physics on the Path to the High Spatial Resolution
Modern numerical models of the Arctic Ocean (AO) exhibit the great progress partly thanks to the fine horizontal resolution, which helps to resolve many of the relevant processes explicitly. Nevertheless, some of the AO features are still modeled poorly by the models with a resolution of 5–10 km. It is anticipated, that the further increase in the horizontal resolution up to 100–1000 m will demand the understanding of the role of the AO specific processes. This paper is a brief review of some of such processes like mesoscale and submesoscale eddies and internal waves, and of the problems of their parameterization, caused by the closeness of their spatial scales. The internal waves and the internal wave-induced mixing are assumed to be the key processes to be taken into account to describe the AO cold halocline mixing properly.
