In a recent paper titled, «Demarcating
circulation regimes of synchronously rotating terrestrial planets within the habitable zone,» my co-authors and I analyze a set of climate model calculations to examine the dependence upon stellar effective temperature of the atmospheric dynamics of planets as they move closer to the inner edge of the habitable zone.

circulation regimes that self - organize into a collective tempo.
A useful aspect

of NHT trend, and by altered character
of ENSO variability.
An expanding area

of whether climate change may be realised as preferred modes
of non-linear naturally occurring atmospheric

There is no accepted single theory, but theoretical explanations
of these vacillating
regime shifts mostly involve variations
of the AMOC (Atlantic Meridional Overturning
Circulation).
The surface katabatic wind
regime, directed equatorwards and down the Antarctic coastal escarpment, closes the lower branch

Several studies (de Vries and Weber, 2005; Dijkstra, 2007; Weber et al., 2007; Huisman et al., 2010; Drijfhout et al., 2011; and Hawkins et al., 2011) have suggested that the sign
of the net freshwater flux into the Atlantic across its southern boundary via the overturning
circulation determines whether or not the AMOC is in a monostable or bistable
regime.
Natural fluctuations don't quite average out (e.g. solar, ocean
circulation regimes) because the system is nonlinear and chaotic and can be «poked» into shifting through an interaction
of external forcing (natural or anthropogenic) and the
circulations of atmospheres and oceans.
