Abstract: In the area of ocean climate modelling we observe a paradigm shift, caused by the end of Moore’s law. This talk describes challenges and opportunities of this paradigm shift. A particular example to respond to the challenges of the computational paradigm shift is given by the new ocean circulation model ICON-O and the Earth System Model ICON-ESM of the Max-Planck Institute of Meteorology. This talk provides a look behind the scenes of ICON-O’s design, given by its main developer. Simulation will be shown and model properties will be explained, with emphasis on the structure-preserving (mimetic) numerics of ICON-O. We outline also the emerging scientific opportunities in ocean and climate modelling that ICON-O allows to explore and report on our first steps on these new research avenues.
Bio: Prof. Dr. Peter Korn is member of the Max Planck Institut for Meteorology, an internationally renowned institute for climate research. Prof. Korn leads the scientific group “Applied Mathematics and Computational Physics”. He is the main developer of the ocean model ICON-O, the ocean component of Max-Planck new Earth System Model ICON-ESM. His scientific interests comprise mathematical and computational fluid dynamics, in particular numerical ocean and atmosphere modelling, as well as data assimilation.
