We review simple instabilities in linear theories of coupled atmosphere-ocean models in both bounded and unbounded ocean basins and describe the mechanisms for instability in these linear theories. We then review nonlinear coupled atmosphere-ocean simulations of the El Nino Southern Oscillation (enso) phenom enon and relate the instabilities seen in linear theory to the fully nonlinear enso simulations. We present a general discussion of the relation between instability and predictability in
