Towards the Salinity Profile Influence on an Internal Wave Attractor Formation

A wave attractor is a peculiar hydrodynamic structure that forms under certain conditions, including vertical stratification of water. Previous studies have mainly focused on wave attractors in fluids with a linear salinity profile. However, more complex non-linear salinity profiles are typical of real water reservoirs. To gain a better understanding of natural wave attractors, it is necessary to study their formation in basins with stratification similar to that found in real oceans. This study aims to compare the properties of wave attractors formed under non-uniform stratification with those formed under linear stratification. Energy accumulation and instability development are studied to clarify the influence of the salinity profile shape on the formation of wave attractors and their properties.
