This magnetic storm has different physical processes at the middle low latitudes and the southern polar cusp region.

分析表明，南极极隙区与中低纬区磁暴形态差异很大。

But without a large prominence eruption, we will not have a magnetic storm here at Earth that drives the brilliant aurora.

但是，如果不发生大喷发，地球将不会受磁暴影响，也就不会产生明亮的极光。

The compression and rotation of the magnetic field serve as an efficient mechanism to cause a large geomagnetic storm.

激波对磁云内禀磁力线的压缩和旋转被证实是增强地磁效应的有效机制。

It is shown that the trapped region will be greatly disturbed during the magnetic storm, and the particle number will vary accordingly.

计算结果认为在磁扰期间捕获区将要发生变化。这个变化引起了捕获区内粒子数目的变化。

Therefore ground-based observations of the magnetic storm is the most basic understanding of the magnetosphere, the most effective means.

因此磁暴的地面观测是了解磁层的最基本、最有效的手段。
