A self-consistent theory describing vortex-wave dynamics in a magnetized plasma has been formulated based on the Hasegawa-Mima equation by extending the modulated point vortex model so as to include the vortex-wave interactions. The energy and entrophy are shown to be conserved in contrast with the previous modulated point vortex description. Dynamical behaviors of vortices under the interaction with waves are numerically studied. A contour dynamics is also shown to be formulated for a magnetized plasma with the temperature gradient.
