32 hour after accidentAt noon on Aug 1



Oslofjord (300m) and Skag (1.5km). 18 Feb at 00:00


Regional models and model areas

Topaz:MyOcean Arctic Monitoringand Forecasting

ROMS 4 km: regional use

ROMS Norkyst 800:Coastal applications


OSI SAF, Satellite derived SST (7 days accumulated) and ROMS 4 temperature

Shall be capable of utilizing available observations,in particular satellite data


NOAA19, channel 1,2,3. May 5, 2011


met.no Sea Ice service analysis, may 5, 2011


Satellite derived SST in the 9. May 2011


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


NWP, regional models, HIRLAM 8 and UM 1 km

Rely on high quality atmospheric forcing, Best possible NWP weather forecasts


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 couplingatmosphere - wave

Average differences in fluxes of sensible heat3 months of HIRLAM - WAM coupled / no coupled

Cold air outbreak->Rougher wind sea ->Increased heat flux

Sætra and Køltzow (IPY results)


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
