Experimental observations of the spontaneous formation of the rotating inertia-gravity wave inside cylindrical container have been carried out. The experimental setup combines both inflow and outflow. The inflow is realized as the overflow of liquid over the container’s edge, while the outflow is performed through an outlet at the bottom of the container’s center. Experiments revealed three different regimes of establishment flow inside the container: 1) flow without formation of the inertia-gravity wave, 2) flow with surface perturbations which are initially localized nearby the container’s wall, and 3) the formation of the rotating inertia-gravity wave.
