Resumen

Coherent structures dominating in the tidal turbulence field inside the Osaka- Bay were detected by flow visualization through satellite image sensors. To obtain the hydrodynamical characteristics, scale down model experiments were done with the Froude/Rossby similarity law. The tidal residual circulations were reproduced on the ensemble mean turbulence field, which is made very similar to each instantaneous turbulence owing to the robustness of the coherent structure interlocked inside a closed vessel. The earth rotation effects were verified to dominate the turbulence processes in this closed vessel, and a hysteresis due to the moon aging was revealed.
