A new phenomenon of the spontaneous development of the rotating inertial gravity wave inside the rigid cylindrical tank has been observed. The experimental set-up combines both the inflow and outflow. Three regimes of the flow inside the tank have been disclosed for the fixed rate of the liquid height change: a) nonrotating flow, b) nonrotating flow with the ripple localized to the tank’s wall, and c) emergence of the rotating inertial gravity wave. The rotating inertial gravity wave forces the fluid to rotate in the opposite direction. Each of these regimes is realized in some ranges of the outlet diameters and liquid heights, and the maps of these regimes are established.
