Abstract

In this paper, the peculiarities of wave dynamics of pulses in incompressible stratified media are considered. It is shown that the character of pulse excitation sources of internal gravity waves is determined by the physical formulation of the problems. For the plane case and in the linear setting, two problems of wave generation for an infinitely long source homogeneous along the horizontal axis are considered. The method of asymptotic analysis of far wave field for different excitation source types is proposed for the three-dimensional case. The estimates of the time of settling the limit harmonic excitation at large distances are determined for the harmonic generation source. It is demonstrated that the effect of harmonic excitation concentration in narrow spatial regions is unlikely under conditions of the real ocean.
