Description
Internal waves are generated in the oceans and atmosphere and play an important role in their energy budgets. The semidiurnal oscillation of the tides over topography in the oceans combined with the density stratification can create internal waves that radiate away from their source. The effect multiple peaks on a single topography has on internal wave generation is explored. Three and four topography peaks create three and four crests respectively in the internal wave beams. Five and six peak topographies generate internal wave beams characterized by two bounding crests and several smaller crests in the middle of the beam. In the far field, the wave beams of the five and six peak topographies resemble that of the plateau topography. Waves are generated at similar wavenumbers regardless of the number of topography peaks as shown by kinetic energy estimates. Kinetic energy is also tightly clustered in a small range of wavenumbers in Fourier space for all topographies.
