Virtual Event: Annual Seminar 2020

In the area of ocean and climate modelling the anticipated end of Moore’s law has motivated efforts to formulate ocean and atmosphere models on unstructured grids. The ocean-sea-ice model ICON-O and the Earth System Model ICON-ESM of the Max-Planck Institute of Meteorology are particular examples of a new generation of ocean and earth system models. This talk provides a look behind the scenes...

The sixth version of the Modular Ocean Model, MOM6, uses the vertical Lagrangian-remap method as the basis of its dynamical core. One of the driving motivations for this approach was to permit generalized vertical coordinates and reduce the numerical mixing associated with the use of Eulerian vertical coordinates. The inspiration for the approach can be traced back to the isopycnal layer...

Unstructured meshes introduce a multiresolution aspect in ocean modeling. Their resolution can be adjusted to practical needs according to the observed eddy activity, the Rossby radius of deformation, or the interest in small-scale dynamics in a particular area. Although the utility of unstructured meshes is well recognized in coastal ocean modeling, global ocean models used in climate studies...
