Analytic and direct modelling

inquiry leaders : Prof Tu ( Australia ) and Assoc Prof Song ( China ) Phase resolving models have now reached the level when they can be explicitly used to conduct analytic studies of broad three-dimensional nonlinear wave development, in their pair mutuality on the boundary level above and wave-mixed layer below. Our inquiry leaders are co-authors of such applications and models. Main targeted deliverables are directing distributions of wind-to-wave energy input and wave-breaking waste ; two-phase model of wave demote .

Spectral modelling

research leaders : Prof Yuan ( China ) and Prof Chalikov ( Australia ) spectral models used for the wave forecast, were a meaning measure ahead when introduced in the 1980s to predict the entail wave altitude. A newfangled generation of this model is feasible. Main targets include coupling of estimate address wave models, such as the nonlinear Schrodinger equation to simulate individual rogue waves, into spectral models ; replacing parametric source terminus for the tip energy input with the fluid mechanics faculty for the tip wave limit level, in order to predict air–sea fluxes to be utilised by GCMs.

Wave-GCM coupling

research leaders : Prof Qiao ( China ) and Assoc Prof Toffoli ( Australia ) Coupling waves with GCMs is a general move in the large-scale air-sea interaction community presently. Our researchers, on both the australian and chinese sides, were among the initiators of this vogue and have importantly contributed to studies of the wave-coupled effects both on the atmospheric and oceanic sides. Within the Centre, chief targets are coupling both teams ’ wave-turbulence mix and wave-induced current schemes into the selections of main GCMs ; validation of the coupled schemes by means of hurricane model, and extending the effort to the climate deepen research.

Experiments and remote sensing

research Leaders : Prof Young ( Australia ) and Prof Huang ( China )

Ultimate validation of any model is constantly against observations, and numerical inquiry outputs are always subject to verification against experiments. The australian and chinese groups have most extensive experimental and data process expertness and access to the best lab, in situ and remote sensing facilities and data, many of them purposefully built and assembled. Main targets are testing ground, in situ and remote-sensing research of dynamics of nonlinear waves, air-sea interactions and upper ocean ; specifically, subsurface kinematics of nonlinear waves, 3D social organization of wave fields, wave-turbulence production below and above the interface and wave-ice interactions .

Extreme conditions

Prof Babanin ( Australia ) and Prof Dai ( China ) There is mounting tell that at extreme weather, regimen of air-sea interactions changes in all the three environments : lower atmosphere, ocean interface and the upper ocean. Our australian and chinese teams, in collaboration with their industry partners, establish the beginning two field sites for closed measurements of the air-sea-wave cycle in tropical cyclones, in the indian Ocean and South China Sea, respectively. The independent targets of this research subject are comprehensive experimental and modelling research of extreme point and other ill understand oceanic conditions ; specifically air–sea fluxes in tropical cyclones and other circumstances of extreme upwind, wave–current interactions and swell propagation .
