“…It has been also demonstrated that, under specific hydraulic conditions, the interaction of a strong flow with a Kelvin wave enhances the progress through which IWs are generated [26]. Because of Kelvin waves, originating from the Arabian Sea and occasionally entering the GoO, this mechanism can play an important role in certain regions of the GoO where favorable hydraulic conditions are satisfied (e.g., east of the Strait of Hormuz) [27][28][29]. More descriptions and references on the mechanisms of IWs generation can be found in [30].…”

A combination of multiple data sources has been used to study the characteristics of internal solitary waves (ISWs) in the Gulf of Oman (GoO). Water column stratification in the Gulf has been examined using field observations and World Ocean Atlas 2018 datasets. The spatiotemporal distribution of ISWs has been obtained from satellite images obtained by means of Synthetic Aperture Radar (SAR) and optical sensors taken from 2018 to 2020. The mechanisms of ISW generation in the GoO have been studied using the data revealed from different available sources. The results show that there are annually two major typical stratifications in the GoO throughout the year, strong stratification in May through September and weak stratification during other months. Dispersion relations corresponding to these types of stratification have been obtained with acceptable accuracy for both deep and shallow regions. The spatiotemporal distribution of ISWs demonstrates that the western and southern regions of the GoO are the hotspots for generation of ISWs in this basin. Several mechanisms of ISW generation in the GoO are discussed including tide, eddies, lee waves, and atmospheric perturbation; the latter one is, apparently, responsible for the appearance of large-amplitude ISWs.
