| 英文摘要 | The role of chaos in the climate system has been dismissed as high dimensional turbulence and noise, with minimal impact on long-term climate change. However theory and experiment show that chaotic systems can be reduced or controlled from high to low dimensionality by periodic forcings and internal feedbacks. High dimensional chaos is somewhat featureless. Conversely low dimensional borderline chaos generates pattern such as oscillation, and is more widespread in climate than is generally recognised. Thus, oceanic oscillations such as the Pacific Decadal and Atlantic Multidecadal Oscillations are generated by dimensionality reduction under the effect of known feedbacks. Annual periodic forcing entrains the El Nino Southern Oscillation. Numerous oceanic and Arctic centered climate oscillations have recently been observed to exhibit delayed synchrony in the manner of a stadium wave. Here, three studied systems with chaotic-nonlinear dynamics (physico-chemical and biological) are reviewed which show dimensionality reduction as a source of emergent pattern. This alongside mathematical studies of chaotic Lorenz models whose trajectories escape under controlling influences from chaotic to non-chaotic phase space regions - incurring a dimensional haircut in the process. Control of chaos by external and internal influences results in lowered phase-space dimensionality with emergent dissipative structure. Dimensionality reduction is proposed as a source of natural climate change. Thus the effect of astrophysical periodic forcing and oceanic and other feedbacks in climate is not so much to generate chaos as to lower dimensionality in a chaotic system, engendering the export of entropy and emergent regular spatiotemporal pattern. |
