Investigation of Air-Sea Turbulent Momentum Flux over the Aegean Sea with a Wind-Wave Coupling Model

Near surface turbulent momentum flux estimates are performed over the Aegean Sea, using two different approaches regarding drag coefficient formulation, a wave boundary layer model (referred here as KCM) and most commonly used Coupled Ocean–Atmosphere Response Experiment (COARE) algorithm. The KCM incorporates modifications in energy-containing spectrum to account for conditions of similarity stratification effects. Airborne turbulence data during an Etesian outbreak Greece processed evaluate simulations. found up 10% higher than COARE ones, indicating that wave-induced may be insufficiently parameterized COARE. Turbulent fluxes measured at about 150 m, reduced their values accounting vertical divergence, consistently lower estimates. Under unstable atmospheric low moderate wind conditions, residuals between measurements less 40%. On other hand, under stable strong winds, majority more This discrepancy is associated with relatively high measurement level, shallow layer, presence level jet.
