As a result, the phenomena I describe above, with the rapid changes
in circulation regimes, are not represented in the climate models at all except as gridcell sized averages...

The
circulation of political notions, behaviours and affiliations are informed
in equally palpable ways by the developments and strategies of sending states,
in addition to those of host
regimes.
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.

Schneider, T., and S. Bordoni, 2008: Eddy - mediated
regime transitions
in the seasonal cycle of a Hadley
circulation and implications for monsoon dynamics.
Several ideas have been put forward to explain this hiatus, including what the IPCC refers to as «unpredictable climate variability» that is associated with large - scale
circulation regimes in the atmosphere and ocean.
Physical properties of the water and satellite estimates of primary productivity were used separately to describe 25 different water masses
in Australia's oceans, identified by different
circulation regimes and oceanographic features.
In like manner, the «stadium wave» climate signal propagates across the Northern Hemisphere through a network of ocean, ice, and atmospheric
circulation regimes that self - organize into a collective tempo.
If the ocean is a bit warmer, the new
circulation regime starts earlier
in the morning, and cuts down the total daily warming.
It results
in step changes and
regimes in upwelling
in the eastern Pacific and
in overturning
circulation in the Atlantic.
Transition to the reverse
regime, likely promoted
in part by anomalies of Pacific
circulations negatively feeds back onto the Atlantic, allow the wave to go around for the reversed climate
regime evolution.
Instead of the
regime of individual «doughnut - shaped»
circulation around each thunderstorm and cumulus cloud, it has all been replaced by long cylinders of air which sink
in the valleys between the serried rows of thunderstorms, and rise up through their centers.
The oscillatory nature of the signal can be thought of
in terms of «braking,» whereby positive and negative feedbacks interact
in such a way as to support reversals of the
circulation regimes.
But there are both long and short term patterns of ocean and atmosphere
circulation that modulate both energy
in and energy out through chaotic
regimes in clouds, ice.
What science is suggesting is that there are multi-decadal
regimes that are related to changes
in ocean and atmospheric
circulation in the broader Earth system.
This becomes more than an academic point as complex
circulation models behave
in the same way, and as the present North Atlantic
in many models is
in the bistable
regime -LRB-[11]-RRB-.
It is seen
in regime changes
in cloud, ice, ocean and atmospheric
circulation, hydrology and biology that are evident
in climate records and that are best described as shifts
in state space on the multi-dimensional climate strange attractor at 20 to 30 year intervals.
Changes
in the upwelling or
circulation regimes could affect dissolved oxygen (DO)
in these regions [4], [27].
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.
Multi-decadal
regime shift — chaotic — unpredictable — involving abrupt shifts
in ocean and atmospheric
circulation — show the dynamical mechanism at the core of climate on a global scale.
Quasi-resonant
circulation regimes and hemispheric synchronization of extreme weather
in boreal summer
Recent records of wintertime extents (
in 2012, 2013, and 2014) appear to be associated with patterns
in air
circulation related to the westerly wind
regime.
These are
in fact inflection points
in the global temperature record associated with
regime shifts seen
in ocean and atmospheric
circulation.
