This coupled system, as explained by Massel, ocean and atmosphere, by their nature, form a thermodynamic coupled system, continuously exchanging heat, mass and momentum on their interface. This means that any forcing that is imposed from one fluid to the other generates a response that will change the interfacial conditions of the system, modifying the boundary between the fluids. Considering the ocean-atmosphere system, waves are the responses from the ocean surface due to external forces.
Wind is generally considered to be the main (though not the only) driving agent behind waves, which can be modeled with a simplified one-dimensional framework in which the ocean surface is replaced by a plane source. Barranco and Cabeza excavated the bottom layer of a 1:10 scale synthetic swell model, in order to analyze the dependence of the wavenumber spectrum of the radiated waves on the sea-state amplitude and other model parameters. This insight, confirmed by baroclinic experiments on a wave tank at the GSI Helmholtz Centre for Heavy Ion Research (GSI, Darmstadt, Germany), allowed to extract a criterion for characterizing the different propagation regimes of the waves, namely the role of horizontal shear and of geostrophic balance on the propagation of the waves. Building on this basic framework, reconstructed sea surface temperature fields provided by global ocean models were used to compute the mean amplitude of the waves simulated in the wave tank. d2c66b5586
