Inertial modes are global oscillations that take place inside rotating objects, such as stars and planets with a fluid core and/or liquid ocean, which result from the restoring effect of Coriolis force. Experimental studies in laboratory have shown these can be excited by action tidal deformation at boundary well precession rotation axis. However, influence inertial on remains unclear.
