We work on the numerical study on a physical mechanism to form a large eddy structure in a surf zone. In particular, we focuses on instantaneous interactions betwen the large-scale vortices and also vortex-surface interactions under breaking waves. You can look at computational animations of the surface deformations and the vortex cores produce under breaking waves.
