| Zusammenfassung |
| The effects of wave-current interactions on shelf ocean forecasts is
investigated in the framework of the MFSTEP (Mediterranean Forecasting
System Project Towards Enviromental Predictions) project. A one way
sequential coupling approach is adopted to link the wave model (WAM) to the
circulation model (SYMPHONIE). The coupling of waves and currents has been
done considering four main processes: wave refraction due to currents,
surface wind drag and bottom drag modifications due to waves, and the wave
induced mass flux. The coupled modelling system is implemented in the
southern Catalan shelf (NW Mediterranean), a region with characteristics
similar to most of the Mediterranean shelves. The sensitivity experiments
are run in a typical operational configuration. The wave refraction by
currents seems to be not very relevant in a microtidal context such as the
western Mediterranean. The main effect of waves on current forecasts is
through the modification of the wind drag. The Stokes drift also plays a
significant role due to its spatial and temporal characteristics. Finally,
the enhanced bottom friction is just noticeable in the inner shelf. |
