This project will use an analytical approach to describe the evolution of ring current ions and electrons during magnetic storms. A more realistic magnetic field and electric field will be used than has previously been done in analytic studies. It will examine the radial transport and loss mechanisms of particles in the inner magnetosphere and will examine the role the ring current and its associated magnetic field play on the particle dynamics. The motion of both electrons and ions will be described using a Hamiltonian formalism. This formalism will allow the model to treat the particle motions even near the inner boundary of the ring current region (L ~ 2).

本计画将使用解析方法来描述磁暴期间环电流离子与电子的演化。 一个更现实的磁场和电场将使用比以前所做的分析研究。 它将研究内磁层中粒子的径向输运和损耗机制，并将研究环电流及其相关磁场对粒子动力学的作用。 电子和离子的运动都将用哈密顿形式来描述。 这种形式使得模型能够处理甚至在环电流区域（L ~ 2）的内边界附近的粒子运动。
