Outline of Final Research Achievements

It is of great importance to develop reliable ocean-atmosphere coupled models for estimating the momentum and scalar exchange rates across the air-sea interface, not only for the prediction of the global carbon and heat cycles closely linked to climate change, but also for the prediction of unusual weather conditions such as hurricanes, typhoons and local heavy rain causing natural disasters. In this study, three-dimensional numerical simulations (DNS and LES) are applied to velocity and scalar (mass concentration and temperature) fields in a wind-driven air-water two-phase flow, and the relationship between turbulence structure and scalar transfer (i.e. mass and heat including latent, sensible and radiative heat) across the wind-driven air-water interface was investigated. The results showed that the scalar transfer across the wind-driven air-water interface was strongly affected by longitudinal vortical structures in the liquid and gas sides.
