Submesoscale telescope experiment

The video shows the visualisation of the “submesoscale telescope experiment” with the ICON ocean model ICON-O. The model was run on a grid with a focus in the North Atlantic. The grid resolution varies between 600m in the North Atlantic and 11km near Australia. This configuration allows us to resolve locally the important dynamical regime of submesoscale dynamics (atmospheric processes of spatial scales below 2 km) within a global set up.

Shown are several flow quantities near the surface such as the velocity magnitude, the magnitude of the gradient of velocity, temperature and vorticity, and an eddy detection via the Q-Criterion. The Q criterion is an important calculation used to identify vortices.
