Modelling of wind-wave interaction under extreme conditions
For coastal defences and development of marine renewables, predicting coastal waves under storm or extreme conditions is one of the key elements for such infrastructures to operate and preform safely and sustainably. However, accurate prediction of storm waves is highly challenging, only not because of the large spatial scale to be considered, but also due to the strong interaction between wind and waves generated by the surface forcing – wind. The nonlinearity of the wave-induced surface friction can affect both the wind distribution near the sea surface and surface waves.
This project is to implement the improved description of wind-wave interaction into the advanced modelling framework which couples the oceanic hydrodynamic and weather models to improve the wave predictions and its impact on the extreme waves, with detailed modelling of flow structure, baroclinic instability and turbulence mixing for applications of coastal defence structures and marine renewable devices.
