Theoretical Modeling of Global Time-Dependent Ground Magnetic Disturbance Patterns and the Electrojet Indices

本项目将利用两个磁亚暴模型，从理论上描述与亚暴相关的全球地面磁扰动模式和场向电流。 所用的两个模型是最初由Kan开发的M-I耦合模型和Zhu和Kan（1989）的电流-磁扰动转换代码。 通过制作地面磁扰动模式的精确理论模型，将有可能改进亚暴研究中地面磁力计数据的利用。

This project will use two models of magnetic substorms to develop theoretical picture of the global ground magnetic disturbance patterns and field-aligned currents associated with substorms. The two models which will be used are the M-I Coupling models originally developed by Kan, and the Current-Magnetic Disturbance Conversion Code of Zhu and Kan (1989). By producing accurate theoretical models of ground magnetic disturbance patterns it will be possible to improve the utilization of ground magnetometer data in substorm research.
