“…In the range of ω ≤ 1.90 rad/s, we find that the wavenumber k is about one order in magnitude larger than the damping coefficient α [33][34][35][36], meaning that viscous effects are weak for these waves. The dispersion relation for coastal Kelvin wave can be solved in a inviscid two-layer model [37] (also see supplementary materials [32]):…”

We experimentally investigate internal coastal Kelvin waves in a two-layer fluid system on a rotating table. Waves in our system propagate in the prograde direction and are exponentially localized near the boundary. Our experiments verify the theoretical dispersion relation of the wave and show that the wave amplitude decays exponentially along the propagation direction. We further demonstrate that the waves can robustly propagate along boundaries of complex geometries without being scattered and that adding obstacles to the wave propagation path does not cause additional attenuation.
