At the water-air surface, the density changes abruptly from ρ = ρwater = 1000 kg/m3 for water to ρ = ρair = 1.2 kg/m3 for air. The solution to model equations is generalised. The mathematical mechanism
of equation solving suggests automatic smoothing of density in the area of wave breaking and formation of a thin fluid layer with an intermediate density.
