The localized electron cyclotron resonance heating power that can suppress sawteeth reconnection often drives m=2 tearing modes in a tokamak operating at constant current. The dynamics of mode onset and coupled mode evolution is described in detail and compared with a nonlinear theoretical model that identifies the effects of mode coupling, finite inertia of the rotating islands, and wall braking. © 1998 The American Physical Society.
