This project will develop a generalized model for the equilibrium conditions for the Earth's magnetic tail during conditions when the magnetosphere is characterized by (1) quasi-steady convection, (2) the growth phase of magnetic substorms, and (3) directly driven solar wind effects. It will use analytic methods in conjunction with a computer simulation code that will ensure appropriate topological conditions and conservation of flux and/or entropy. The result will be an equilibrium model that can be embedded in a Geospace General Circulation Model, or other global magnetohydrodynamic (MHD) simulations of the magnetospheric system.

该项目将为磁层的特点是（1）准稳定对流、（2）磁亚暴的增长阶段和（3）直接驱动的太阳风效应时的地球磁尾平衡条件建立一个通用模型。它将结合计算机模拟代码使用分析方法，以确保适当的拓扑条件和通量和/或熵的守恒。其结果将是一个可嵌入地球空间环流模型或磁层系统的其他全球磁流体动力学模拟的平衡模型。
