1·A geomagnetic storm is brewing.
一场电磁风暴正在酝酿。
2·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。
3·In this paper, the stratification events of the ionosphere related to geomagnetic storm in the night-time over Wuchang are studied.
本文研究了武昌上空与磁暴有关的电离层夜间分层事件。
4·And while aurorae are normally visible only at high latitudes, they can light up the sky even at lower latitudes during a geomagnetic storm.
虽然极光通常只出现在高纬度地区，但是在磁暴发生时，极光也能点亮稍低纬度地区的天空。
5·This striking aurora image was taken during a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun on May 24, 2010.
这张惊人的极光图片在一场极有可能由2010年5月24日来自太阳的日冕物质抛射引起的地磁风暴期间拍摄的。
6·The resulting solar storm could cause a geomagnetic storm on Earth, knocking out electricity grids around the world for hours, days, or even months, bringing much of normal life grinding to a halt.
由其引发的太阳风暴可能会激发地磁场风暴，届时，全球电网瘫痪，时间将长达数小时，数天，甚至几个月，大量的生产生活将无法继续进行。
7·Z (Changes in the Vertical field) for the sudden storm commencements and geomagnetic bays to the northeast and southwest of this line appear opposite in signs.
此线的东北与西南，地磁湾扰、磁暴急始等短周期事件垂直分量的变化△z 呈现反号。
