The behavior of a vortex ring convecting in a rotating fluid is investigated by the numerical simulation. The convection direction is parallel to the rotation axis of the fluid. The simulation highlights the flow and vorticity fields induced by the Coriolis force around the vortex ring. An axial vorticity appears along the central axis of the vortex ring, and secondary vortex rings occur at the front and rear of the vortex ring. The simulation also demonstrates that the decay of vortex ring is enhanced by the secondary vortex ring.
