Abstract

When external force, such as wind, is given in a two-layer system, internal waves are induced with a larger amplitude compared to surface waves. In general, when the internal Rossby radius is smaller than the spatial scale of an enclosed bay or lakes, internal Kelvin waves occur in a two-layer system easily. Then, the internal Kelvin waves progress over a uniform slope, the different type of internal wave breaking is expected to occur due to the Coriolis effect. Therefore, this study aims to clarify the influence of the Coriolis effect on the breaking of internal Kelvin waves by using laboratory experiments and numerical analysis. As a result, residual horizontal circulation is found to appear around the density interface.
