| The problem of wave packets propagation at the interface between the two liquid layers of different densities, is considerwd. The liquid is assumed to be ideal and incompressible and the surface tension is taken into account at the interface. The analysis of the influence of geometric and physical parameters on the crest and bottom scewness of wave packets. It is shown that taking into account the second approximation leads to apperance of the scewness of crests and bottoms. In particular, in the case of modulation instability, the blunting or sharpening of envelope takes place. |
