摘要：

The problem of constructing uniform asymptotics for the far fields of internal gravity waves generated by a pulsating localized source of perturbations in finite-depth stratified medium flow is considered. The solutions obtained describe the wave perturbations both inside and outside the wave fronts and can be expressed in terms of the Airy function and its derivatives. Numerically calculated wave patterns of the excited wave fields are presented.
