The Dual Nature of Chaos and Order in the Atmosphere

Summary

This article argues that weather and climate should be viewed as a mixture of chaotic and ordered processes rather than as purely chaotic systems. Using Lorenz models and generalized Lorenz models, the authors show how steady-state, chaotic, and limit-cycle solutions can coexist under different parameter regimes. The revised view helps separate sensitive dependence on initial conditions from more predictable oscillatory or stable behavior, providing a framework for thinking about short-term limits and longer-range predictability within the same atmosphere.
