Drift waves and vortices are low-frequency phenomena that occur in inhomogeneous plasmas embedded in strong magnetic fields. They propagate in the direction perpendicular to the density gradient and to the magnetic field with phase velocities that are characterized by the diamagnetic velocity. Drift waves and vortices propagate in complementary velocity intervals.
