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

这项拨款支持对太阳风的调查， 利用地面磁记录研究地球磁层 从世纪之交到现在， 行星际测量时可用。 本研究将 研究行星间磁场的控制 地磁活动，磁层的响应， 1910年哈雷彗星对太阳风的阻挡; 磁层的快速减少的动量通量， 太阳风，行星间冲击的减速接近1 Au、地磁暴的统计特性和 亚暴强度的量化。 该研究将采用 世界数据中心A的集合，包括其 新制作的光盘和在 国际磁层研究。 除了帮助 我们对太阳风和太阳风之间的耦合的理解 地球的磁层及其在上个世纪的变化， 这项研究将有助于测试光盘和国际监测系统数据的准确性 并帮助纠正这些数据。

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.
