It is proposed to analyze the non-linear response of the Earth's magnetospheric system as driven by the solar wind. The newly developed technique of non-linear input/output analysis will determine the non-linear behavior of the magnetosphere. Previous linear analyses have been incapable of exploring the non-linear dynamics; previous non-linear analyses have treated the magnetosphere as an autonomous system, which clearly neglects the major effects of the solar wind. Under the assumption that the electrojet indices are valid diagnostics of the state and dynamics of the magnetosphere, the time series of the electrojet indices will be analyzed as a function of the solar wind parameters for the years 1978 and 1979. The identification of low dimensional non- linear dynamics in the magnetospheric system will lead to much better short term predictions of the solar wind and magnetosphere. conversely, a definite demonstration of the absence of such deterministic behavior will help to guide future efforts aimed at modelling the magnetosphere.

提出了分析地球的非线性响应， 太阳风驱动的磁层系统。 新 非线性输入/输出分析的发展技术将 确定磁层的非线性行为。 先前 线性分析无法探索非线性 动力学;以前的非线性分析处理 磁层作为一个自治系统，这显然忽略了 太阳风的主要影响。 的假设下 电喷射指数是状态和动力学的有效诊断 的磁层，时间序列的电射流指数 将作为太阳风参数的函数进行分析， 1978年和1979年。 低维非线性的识别 磁层系统中的线性动力学将导致 更好的太阳风和磁层的短期预测。 相反，明确证明没有这种 确定性行为将有助于指导未来的努力， 模拟磁层。
