Coupled ocean-atmosphere numerical simulation for the Adriatic Sea: ocean outcomes

Although some authors have shown that wave–current interactions are not negligible, wave setup onsea level is often not considered in modeling the Adriatic Sea. Other studies have demonstrated thatusing a coupled ocean-atmosphere-wave model can improve the simulation of extreme events,particularly when high-resolution sea surface temperature (SST), consistently updated with oceancirculation, is essential for determining heat fluxes. Thus, modeling efforts are increasingly movingtowards two-way current–wave, current–atmosphere, and current–wave–atmosphere coupled systems.In this study, we present a high-resolution ocean-atmosphere numerical simulation for the Adriatic Sea,where the Weather Research and Forecasting (WRF) model is two-way coupled within the COAWST(Coupled Ocean–Atmosphere–Wave and Sediment Transport) modeling system. The system integratesROMS (Regional Ocean Modeling System) for ocean circulation and SWAN (Simulating WavesNearshore) as wave driver. The long-term high-resolution simulation has multiple purposes: torepresent Adriatic Sea circulation from the basin scale to the coastal dynamics, to study extreme eventswhere atmosphere-ocean interactions are crucial, and to provide the starting framework (initial andboundary conditions) for very high-resolution simulations needed for nearshore applications such ascoastal flooding and erosion.In this effort, the model's performance will be evaluated, focusing on thermohaline properties andocean circulation. Validation results will be presented during the talk.
