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

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
