Far fields of internal gravity waves in stratified media of variable depth
В. В. Булатов, Yu. V. Vladimirov · Russian Journal of Mathematical Physics · 2010
The present paper is devoted to presenting the solution of the problem on the far field of internal gravity waves in a stratified medium whose depth linearly depends on the space variable. Uniform asymptotic representations of solutions are constructed; these representations enable us to describe the far fields of internal gravity waves excited by a moving source and characterize the main specific features of the wave fields near caustics and wave fronts.
