Surface waves and their resulting turbulent processes play a central role in regulating the exchanges of mass, momentum, and energy between the atmosphere and ocean, directly influencing sea states, weather patterns, and climate systems. Although integrating the dynamics of surface waves into the coupled atmospheric-oceanic models is crucial for accurate weather and climate forecasts, the current understanding of fundamental processes that link the turbulent flow structures above and below the surface within the coupled air-sea boundary layers is limited. This is due to challenges in resolving the dynamics of small-scale turbulence in the vicinity of the air-sea interface. This project will combine high-resolution laboratory experiments, high-fidelity numerical simulations, and foundational AI techniques to examine the multiscale turbulence above and below ocean surface waves and quantify the two-way coupled air-sea momentum and energy fluxes at the air-sea interface. This project will examine the coupling of wave-induced flow structures above and below the air-sea interface. A synergistic experimental and AI-driven approach will be used to develop a comprehensive parameterization of wave and turbulent stresses at the air-sea interface. The aim is to address the turbulent closure problem in the governing equations and improve predictive models of air-sea fluxes.
