Surface waves can be generated when air blows over a water body. A turbulent boundary will then develop on the air/water interface. The flow structure over the moving interface substantially affects the turbulent transfers of matter, momentum and energy, but far from fully understood. We have recently constructed a numerical model for directly simulating the interactions between air and water across free interfaces. The code is characterized by the following important numerical aspects: (1) the fluid dynamics is computed by the VSIAM3 (Volume/Surface Integrated Average based Multi-Moment Method), a 3D finite volume method using multi-integrated moments (2) the moving interface is explicitly captured by an efficient algebraic front capturing method, THINC scheme. We have conducted test simulations for the wind-driven waves across the air/water interfaces using the Earth Simulator and it has been shown that our numerical code is practical and efficient to calculate largescale simulations.
