Local surface deformations of the wave breaking jets were computed using a three-dimensional large eddy simulation. The typical counter-rotating vortices formed with the jet entrains the adjacent jet surface into inner fluid to penetrate the jet, forming a so-called finger jets. The tips of the fingers are fragmented into sprays. The breakup rate of the fingers and the volume fraction of the resulting sprays have also been statistically estimated in this paper. It has been found that local acceleration along the fingers determines the breakup rate as well as the fluid fraction.
