Here, they can create geomagnetic storms capable of disrupting long-range communication and causing blackouts.

掀磁风暴，由此能扰乱远距离通信并引大规模停电。

Without the geomagnetic field, that solar wind would hit the Earth's atmosphere directly.

如果没有磁场，太阳风就会直接撞的大气层。

So what causes these geomagnetic storms?

那么是什么导致了这些磁暴呢？

The more natural way that this could happen is with a severe geomagnetic disturbance, or GMD.

发生这种情况的更自然的方式是发生严重的磁扰动（GMD）。

This celestial display known as the Northern Lights is caused by a geomagnetic storm.

这种被称为北极光的天象是由磁暴引的。

In 1859 a geomagnetic storm ignited by a huge solar flare created Auroras as far south as Rome.

1859年，一个巨大的太阳耀斑引发的磁暴在远在罗马这样的南方制造了极光。

The last time we had a big power outage due to a geomagnetic storm was in the 80s.

上次由于磁风暴造成大停电是在80年代。

If directed at Earth, these flares and CMEs create geomagnetic storms that then dazzle us with spectacular auroras.

如果是直接, 这些耀斑和日冕物质抛射创造的磁暴会通过壮观的极光让我们眼花缭乱。

Around the same time, there was a " geomagnetic storm watch" listed by the U.S. Space Weather Prediction Center.

大约在同一时间，美国空间天气预报中心列出了一个" 磁风暴观察" 。

We call it a geomagnetic storm or a geomagnetic disturbance.

我们称之为磁风暴或磁扰动。

Did the sunspots cause the geomagnetic fields or did the geomagnetic fields cause the sunspots?

是太阳黑子导致了磁场还是磁场导致了太阳黑子？

Not the intensity of the geomagnetic disturbance itself.

不是磁干扰本身的强度。

He said that the incident is believed to be the largest collective loss of satellites from a single geomagnetic event.

他说，该事件被认为是单次磁事件造成的最大规模卫星集体损失事件。

Without satellites, we wouldn’t be ready for geomagnetic storms either.

没有卫星， 我们也不会为磁风暴做好准备。

Without satellites, we wouldn't be ready for geomagnetic storms either.

如果没有卫星，我们也无法做好应磁风暴的准备。

The Northern Lights are more visible than usual because of a geomagnetic storm which disrupted the Earth's magnetic field.

由于磁风暴扰乱了磁场，北极光比往常更加清晰可见。

And the timing of this geomagnetic storm with an erupting volcano in Iceland puts nature on full display.

这场磁风暴和冰岛火山的喷发正好同时发生，将大自然的魅力展现得淋漓尽致。

No? Well, geomagnetic activity, the natural variations in Earth’s magnetic field, it fluctuates in 11-year cycles.

嗯，磁活动，磁场的自然变化， 它以 11 年的周期波动。

I am actually building mathematical  models to understand how birds are using the geomagnetic field to migrate.

实际上，我正在建立数学模型来了解鸟类如何利用磁场进行迁徙。

It's no longer just that, as you go further south you have on average, less intense geomagnetic disturbances.

- 不仅仅是这样， 随着你向南走得更远，平均而言，磁干扰强度会减弱。
