Do we need fine scale ocean prediction ?! ... and if so, do we have the right tools ? Lars-Anders Breivik OPNet Oslo, May 2011
Heading Oil drift simulations using two different resolutions Red 4 km model Blue 1.5 km model 32 hour after accident At noon on Aug 1
Oslofjord (300m) and Skag (1.5km). 18 Feb at 00:00
Regional models and model areas ROMS 4 km: regional use ROMS Norkyst 800: Coastal applications Topaz: MyOcean Arctic Monitoring and Forecasting
Shall be capable of utilizing available observations, in particular satellite data OSI SAF, Satellite derived SST (7 days accumulated) and ROMS 4 temperature
High resolution model: Norkyst 800
Eddy shedding in the model. Daily mean surface currents for May 3 - 8, 2010, in the ocean west of Lofoten
Rely on high quality atmospheric forcing, Best possible NWP weather forecasts NWP, regional models, HIRLAM 8 and UM 1 km
Future direction: Coupling of ocean forecast / wave forecast and weather forecast models to optimize the description of the fluxes in the boundary layer.
Experience with coupling atmosphere - wave Average differences in fluxes of sensible heat 3 months of HIRLAM - WAM coupled / no coupled Cold air outbreak-> Rougher wind sea -> Increased heat flux Sætra and Køltzow (IPY results)
Experience with coupling wave - ocean 1-year storm surge simulations • Control run with stress calculated from Large and Pond • Experiment using stresses from wave model • Verification against sea level observations From Sætra, Albretsen and Janssen 2007 (JPO)
