Not chaotic implies the converse. None of the model behaviors (ENSO, QBO, or Chandler wobble) are dependent on initial conditions -- instead they are sensitive to continuous (including annual) forcing, with any perturbations quickly damping out.

Is having a winter season sensitive to initial conditions? Is having a daily warming sensitive to initial conditions? Thought not.
