本文探讨了温彻斯特模式（Horton和Doxas，1998）的动力学范围。这种低维模型为我们理解磁层内简单物理量（如能量沉积、宏观电流、跨尾电压等）之间的关系提供了工具。而不需要处理更完整但笨重的模型（例如，MHD或粒子代码）。该模型是高度通用的：参数空间的某些区域支持稳定的不动点，而其它区域包含呈现倍周期和有时混沌的周期状态。在这些制度（稳定，周期性，混乱）的国家进行了调查，他们的能力，准确地描述所观察到的磁层电离层系统的特性。简要讨论了这个模型的应用程序，目前的空间物理问题。
This paper explores the dynamical range of the WINDMI model (Horton and Doxas, 1998]. Such low-dimensional models provide us with the tools to understand the relationships of simple physical quantities within the magnetosphere (such as energy deposition, macroscopic currents, cross-tail voltage, etc.) without the necessity of coping with the more complete but unwieldy models (MHD or particle codes, for example). The model is highly versatile: certain regions of the parameter space support stable fixed points, while others contain periodic states that exhibit period doubling, and sometimes chaos. States in each of these regimes (stable, periodic, chaotic) are investigated for their ability to accurately describe the observed properties of the magnetosphere-ionosphere system. A brief discussion of applications of this model to current space physics problems is included.
