Аннотация
Application of different approaches for visualization of hydrodynamic fields of internal waves is closely connected with the possibility of extracting important numerical characteristics of the flows. In this paper we describe methods of visualisation, which were shown to be very effective for the illustration of the internal wave attractors both for laboratory experiments and numerical simulations. On the other hand, some novel approaches for description of the wave flows with accumulation of energy are discussed. Methods of vortices identification show interesting properties of the wave flows, and may give an alternative for the estimation of the width of wave beams. At the same time, the limitations of the applicability of the described methods strongly depend on the space and time resolution of the available data, which is especially important in the areas of the internal wave beam reflection.
