But some papers give the indication that the strong instability/variability of the thermohaline circulation under traditional mixed boundary conditions cannot possibly occur when a more realistic SST condition is used. Yet that's not true of some current models - e.g.: - some LSG/EBM configurations still oscillate, - the Manabe & Stouffer 1988 coupled model had two stable states, - Mikolajewicz and Maier-Reimer 1994 still could collapse NADW even with a reduced coupling of 16 W/m**2/K (I note your caveat about the lack of scale dependence though), - the Stocker et al 1992 zonally averaged coupled model had multiple
