FISSION LAWS OF INITIALLY INTERFACE SOLITARY WAVES IN TWOLAYER OCEAN

A 2-D KdV equation of two-layer stratified ocean with 2-D topography is recapitulated in the present paper.Based on a reduced version of this 2-D KdV equation,the fission laws of the initially internal solitary waves are studied by means of numerical calculation.From the numerical results,it is shown that the initially interface solitary waves can fission on the continental slope like the initially surface solitary waves and the fission process is a significant generating mechanism of internal interface soliton packet on the continental shelf.
