The Impact of a Reduced High-wind Charnock Parameter on Wave Growth With Application to the North Sea, the Norwegian Sea and the Arctic Ocean
Øyvind Breivik, Ana Carrasco, Hilde Haakenstad +8
As atmospheric models move to higher resolution and resolve smaller scales, the maximum modeled wind speed also tends to increase. Wave models tuned to coarser wind fields tend to…
A comparison of data-driven approaches to build low-dimensional ocean models
Niraj Agarwal, Dmitri Kondrashov, Peter Dueben +2
We present a comprehensive inter-comparison of linear regression (LR), stochastic, and deep-learning approaches for reduced-order statistical emulation of ocean circulation. The re…
Machine-Learned Preconditioners for Linear Solvers in Geophysical Fluid Flows
Jan Ackmann, Peter D. Düben, Tim N. Palmer +1
It is tested whether machine learning methods can be used for preconditioning to increase the performance of the linear solver -- the backbone of the semi-implicit, grid-point mode…
Surface Wave Effects in the NEMO Ocean Model: Forced and Coupled Experiments
Øyvind Breivik, Kristian Mogensen, Jean-Raymond Bidlot +2
The NEMO general circulation ocean model is extended to incorporate three physical processes related to ocean surface waves, namely the surface stress (modified by growth and dissi…
Wind and Wave Extremes over the World Oceans from Very Large Ensembles
Øyvind Breivik, Ole Johan Aarnes, Saleh Abdalla +2
Global return values of marine wind speed and significant wave height are estimated from very large aggregates of archived ensemble forecasts at +240-h lead time. Long lead time en…
Approximate Stokes Drift Profiles in Deep Water
Øyvind Breivik, Peter A E M Janssen, Jean-Raymond Bidlot
A deep-water approximation to the Stokes drift velocity profile is explored as an alternative to the monochromatic profile. The alternative profile investigated relies on the same…
