A Study of the Solar Wind Interaction with the Earth's Magnetosphere: Storms, Substorms and Sudden Impulses

这笔赠款支持利用本世纪之交至今的地面磁记录，结合星际测量(如果有的话)，对太阳风与地球磁层的关系进行调查。这项研究将考察行星际磁场对地磁活动的控制，磁层对1910年哈雷彗星阻挡太阳风的响应，磁层对太阳风动量通量迅速减少的响应，行星际激波在1AU附近的减速，地磁暴的统计特性和亚暴强度的量化。这项研究将使用世界数据中心A收集的资料，包括其新生产的光盘上的资料和在国际磁层研究期间收集的数据。除了有助于我们理解太阳风和地球磁层的耦合以及它在上个世纪的变化之外，这项研究还将有助于测试CDROM和IMS数据集的准确性，并有助于对这些数据进行校正。

This grant supports an investigation of the solar wind with the terrestrial magnetosphere using ground-based magnetic records from the turn of the century to the present in conjunction with interplanetary measurements when available. This study will examine the control by the interplanetary magnetic field of geomagnetic activity, the response of the magnetosphere to the blockage of the solar wind by comet Halley in 1910; the response of the magnetosphere to rapid reductions of the momentum flux in the solar wind, the deceleration of interplanetary shocks near 1 AU, the statistical properties of geomagnetic storms and the quantification of substorm magnitudes. The study will employ the collections of the World Data Center A including those on their newly produce CDROM and the data collected during the International Magnetospheric Study (IMS). In addition to aiding our understanding of the coupling of the solar wind and the Earth's magnetosphere, and its variation over the last century, this study will help test the accuracy of the CDROM and IMS data sets and aid in the correction of those data.
