«The Earth's rotational acceleration has been used to define different
atmospheric circulation regimes (Lamb, 1972), and shows a 60 year cycle with maxima near 1860 and 1920 (Lambeck, 1980).»
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.

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.
Three of these five intervals coincided with multidecadal hemispheric climate -
regime shifts, which were characterized by a switch between distinct
atmospheric and oceanic
circulation patterns, a reversal of NHT trend, and by altered character of ENSO variability.
An expanding area of research since the SAR is the consideration of whether climate change may be realised as preferred modes of non-linear naturally occurring
atmospheric circulation patterns, or so - called weather
regimes as proposed by Palmer (1999).
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.
iv) and Pacific
atmospheric circulation anomalies negatively feeding back onto the Atlantic freshwater balance 609 through remote modification of precipitation
regimes.»
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.
So the question to me is: are there reasons for concern that Earth's large - scale
atmospheric circulation could be disrupted by climate change into an entirely new
regime, with completely different
circulation patterns?
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.
These are in fact inflection points in the global temperature record associated with
regime shifts seen in ocean and
atmospheric circulation.
