GEM: Steady Magnetospheric Convection Events and Solar-Wind/Magnetosphere Coupling

该项目包括对稳定磁层对流（SMC）事件的性质和原因进行数据分析和理论研究。SMCs是在没有亚暴发生的情况下地磁活动升高的延长间隔。该项目的目标是：(1)通过统计比较SMCs与非SMCs周期的特性来进一步了解SMCs，(2)通过使用SMCs作为驱动SMCs的特殊太阳风条件的探测来进一步了解太阳风/磁层耦合，(3)进一步了解突发体流（BBfs）与亚暴运输相比如何传输磁通量，能量和动量。(4)探索在特定太阳风条件下SMCs发生的新思路。

This project involves a data-analysis and theoretical investigation into the properties and causes of steady magnetospheric convection (SMC) events. SMCs are extended intervals of elevated geomagnetic activity without the occurrence of substorms. The objectives of this project are (1) to further our understanding of SMCs by statistically comparing their properties with the properties of non-SMC periods, (2) to further our understanding of solar-wind/magnetosphere coupling by using SMCs as a probe of the special solar wind conditions that drive SMCs, (3) to further our understanding of how bursty bulk flows (BBfs) transport magnetic flux, energy and momentum in comparison with substorm transport, and (4) to explore new ideas about why SMCs occur under certain solar wind conditions.
