High-resolution ocean and climate modelling on unstructured grids: from finite elements to finite volumes

This talk will give an overview about the ocean model developments at the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research, and summarise example applications made possible by using a novel numerical core. The Finite Element Sea Ice-Ocean Model (FESOM1.4) supports multi...
