Zusammenfassung: | The paper considers the problem about mathematical modeling of internal gravity waves in ocean of finite depth with an arbitrary distribution of buoyancy frequency excited by moving perturbation source. In the linear formulation, the main dispersion characteristics determining the properties of excited far wave fields are analytically and numerically investigated. It is shown that far wave fields of an individual mode is a sum of separate wave packages. The phase and amplitude structures of far fields of internal gravity waves from moving perturbation sources are numerically investigated for various modes of wave generation. |
