This project will further develop the WINDMI model of the magnetospheric tail and its interaction with the ionosphere. The technique used is the reduction of the system to a dynamical model with a small number of dynamical parameters. This reduction to a low dimensional order makes it possible to model and predict the behavior of the system without resorting to extremely complex numerical simulations such as MHD simulations and kinetic particle simulations. This model is of particular applicability to the growth, triggering and recovery of magnetospheric substorms.

该项目将进一步发展关于磁层尾部及其与电离层相互作用的WINDMI模型。所使用的技术是将系统简化为具有少量动力学参数的动力学模型。这种降到低维的阶数使得可以对系统的行为进行建模和预测，而不需要求助于极其复杂的数值模拟，例如MHD模拟和动力学粒子模拟。该模型对磁层亚暴的生长、触发和恢复具有特殊的适用性。
