We present an asymptotic theory for the long-time evolution of an intense barotropic vortex on the b-plane. Three stages are described: first, the near-field development of b-gyres; second, the intensification of the quadrupole and secondary axisymmetric components with vortex deceleration; third, the vortex decay. Our theory takes account of all three stages and provides estimates for the vortex lifetime.
