Representing the Surface Ocean in ECMWF's data-driven forecasting system AIFS
Sara Hahner, Lorenzo Zampieri, Jean-Raymond Bidlot +22
Machine-learning (ML) models, such as the AIFS at the ECMWF, have revolutionised weather forecasting in recent years. We present an extension of the AIFS that jointly models the at…
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 Stokes drift approximation based on the Phillips spectrum
Øyvind Breivik, Jean-Raymond Bidlot, Peter A. E. M. Janssen
A new approximation to the Stokes drift velocity profile based on the exact solution for the Phillips spectrum is explored. The profile is compared with the monochromatic profile a…
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…
Waving in the rain
Luigi Cavaleri, Luciana Bertotti, Jean-Raymond Bidlot
We consider the effect of rain on wind wave generation and dissipation. Rain falling on a wavy surface may have a marked tendency to dampen the shorter waves in the tail of the spe…
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…
Wind and Wave Extremes over the World Oceans From Very Large Forecast Ensembles
Øyvind Breivik, Ole Johan Aarnes, Saleh Abdalla +1
Global return value estimates of significant wave height and 10-m neutral wind speed are estimated from very large aggregations of archived ECMWF ensemble forecasts at +240-h lead…
Wave Extremes in the North East Atlantic from Ensemble Forecasts
Øyvind Breivik, Ole Johan Aarnes, Jean-Raymond Bidlot +2
A method for estimating return values from ensembles of forecasts at advanced lead times is presented. Return values of significant wave height in the North-East Atlantic, the Norw…
A high-resolution hindcast of wind and waves for The North Sea, The Norwegian Sea and The Barents Sea
Magnar Reistad, Øyvind Breivik, Hilde Haakenstad +3
A combined high-resolution atmospheric downscaling and wave hindcast based on the ERA-40 reanalysis covering the Norwegian Sea, the North Sea and the Barents Sea is presented. The…
