We consider a coupling of the Stommel Box and the Lorenz models, with the goal of investigating the so-called "crises" that are known to occur given sufficient forcing. In this context, a crisis is characterised as the bifurcation of a system that is produced by the application of forcing to a bistable system, thereby reducing it to a monostable system. We document the variety of chaotic attractors and crises possible in our model and demonstrate the possibility of a merging between the stable chaotic attractor that persists after a crisis with either a chaotic transient or a ghost attractor. An investigation of the finite time Lyapunov exponents around crisis levels of forcing reveals a strong alignment between the first Stommel and neutral Lorenz exponents, particularly at points of a trajectory most sensitive to divergence around these levels. We discuss possible predictors that may identity those chaotic attractors liable to collapse as a consequence of a crisis and show the chaotic saddle collisions that occur in a boundary crisis. Finally, we comment on the generality of our findings by coupling the Stommel Box model with other strange attractors and thereby show that many of the behaviours are quite generic and robust.
