Some 2,200 kilometers beneath our feet lies the outer core, a molten layer of
rock that moves constantly. This rotation creates the planet’s natural
magnetic field. For decades, scientists had observed the core rotating
primarily westward. But in 2010, something bizarre happened: the flow beneath
the Pacific Ocean suddenly reversed direction and began surging east. The
reason for this rebound is still unclear.
Thanks to satellites like ESA’s Swarm and CryoSat, researchers gathered
detailed measurements of small changes in the strength of Earth’s magnetic
field.
在我们脚下约2200公里处是地核，这是一层不断移动的熔融岩石层。这种旋转产生了地球
的天然磁场。几十年来，科学家观测到地核主要向西旋转。但在2010年，一件奇特的事情
发生了：太平洋下方的地核流动方向突然逆转，开始向东涌动。这种反转的原因至今仍不
清楚。
借助欧洲太空总署的 Swarm 和 CryoSat 等卫星，研究人员收集了地球磁场强度微小变化
的详细测量数据。
The team analyzed almost 30 years (1997–2025) of data collected by ground
stations and satellite missions, including ESA’s Swarm and CryoSat, Germany’
s CHAMP, and Denmark’s Ørsted. The results call into question long-held
assumptions about the outer core being stable.
This reversal indicates that explosive things are happening deep within the
Earth, allowing us to glimpse new clues about how such magnetic fields come
into being. It also provides an indication of potential new, previously
unrecognized connections between what is happening in the outer core and
changes occurring deeper in the Earth.
研究团队分析了近30年（1997-2025年）间由地面站和卫星任务收集的数据，其中包括欧
洲太空总署的Swarm和CryoSat卫星、德国的CHAMP卫星以及丹麦的Ørsted卫星。研究结果
对长期以来关于地核外层稳定的假设提出了质疑。
这种逆转显示地球深处正在发生剧烈的变化，让我们得以窥见磁场形成的新线索。它也暗
示著外核的变化与地球深处的变化之间可能存在着先前未被发现的关联。
Lead author of the study, Frederik Dahl Madsen, of the University of
Edinburgh – School of Geosciences, said, “The large-scale flow reversal
beneath the Pacific raises new questions about the behavior of Earth’s deep
interior. Scientists now want to understand whether the reversal represents a
short-lived fluctuation, part of a repeating oscillation, or a new stable
equilibrium for core circulation. Continued monitoring will be essential to
determine how the flow evolves over the coming years.”
The geodynamo is driven by the circulation of molten iron in the outer core
around the solid inner core, and it is this circulation that maintains Earth’
s magnetic field. Despite the highly dynamic nature of this circulation, most
of its main flow patterns remained stable over several decades.
该研究的第一作者、爱丁堡大学地球科学学院的弗雷德里克·达尔·马德森表示：“太平
洋下方的大规模环流逆转引发了关于地球深部内部行为的新问题。科学家们现在想要了解
，这种逆转究竟代表短暂的波动、周期性振荡的一部分，还是地核环流的一种新的稳定平
衡状态。持续监测对于确定未来几年环流的演变至关重要。”
地磁发电机是由外核中熔融铁围绕固态内核的循环所驱动的，正是这种循环维持着地球磁
场。尽管这种循环具有高度动态性，但其大部分主要流动模式在数十年间都保持稳定。
In 2013, ESA launched the trio of Swarm satellites, each carrying ultrasensitive magnetometers. These satellites, flying in precisely coordinated
orbits, can separate magnetic signals originating in the core from those
originating in the crust, oceans, atmosphere, and space.
This accuracy has allowed scientists to piece together the evolution of flows
at the core–mantle boundary over time. There were unexpected things
associated with these reconstructions, for example, the Pacific reversal in
2010 or the sharp ‘geomagnetic jerk’ of 2017, which showed that Earth’s
deep interior is capable of undergoing rapid and unpredictable changes.
2013年，欧洲太空总署发射了三颗“群星”（Swarm）卫星，每颗卫星都携带超灵敏的磁
力计。这些卫星在精确协调的轨道上飞行，能够将源自地核的磁讯号与源自地壳、海洋、
大气层和太空的磁讯号区分开来。
这种精确度使得科学家能够拼凑出地核-地函边界处流体随时间的演变过程。这些重建结
果也揭示了一些意想不到的现象，例如2010年的太平洋磁极反转和2017年的剧烈“地磁突
变”，这些都表明地球深部内部能够发生快速且不可预测的变化。
According to ESA’s Swarm Mission Manager, Anja Stromme, the long-term
dataset provided by Swarm is important for this study. She noted, “Although
Swarm was launched after the dramatic reversal event of 2010, it has provided
high-precision data that tells us about Earth’s inner core in the period
that followed.
The broader data set also revealed the more nuanced, wave-like accelerations
and rapid flow changes buried within less precise records. That research
indicates the eastward flow beneath the Pacific may be waning, signaling a
possible deceleration of a much larger oscillation, or longer cycle, in Earth
’s deep interior.
At its core lies the swirling molten iron of the outer layer, from which much
of Earth’s magnetic field originates, protecting us from particles emitted
by the Sun. The atmosphere and our technological systems would be much more
exposed to debilitating radiation coming from the Sun without that shielding
field.
据欧洲太空总署“蜂群”任务经理安雅·斯特罗姆称，“蜂群”提供的长期数据集对这项
研究至关重要。她指出：“尽管‘蜂群’是在2010年剧烈的逆转事件之后发射的，但它提
供了高精度数据，让我们了解了此后一段时间内地球内核的情况。”
更广泛的数据集还揭示了隐藏在精度较低的记录中的更微妙的、波动性的加速度变化和快
速的流速变化。这项研究表明，太平洋下方的东向流动可能正在减弱，这预示着地球深部
内部更大幅度的振荡或更长周期的周期可能正在减速。
地球的核心是外层翻腾的熔融铁，地球磁场的大部分就源自于此，它保护我们免受太阳辐
射粒子的侵害。如果没有这层屏蔽层，大气层和我们的科技系统将更容易受到来自太阳的
有害辐射的侵害。
However, the magnetic field is not fixed. Over time, it slowly changes as the
flow patterns in the core evolve, making navigation systems less accurate and
spacecraft communications useless, along with models of near-Earth space
weather. There are thus both scientific and technical (as well as societal)
reasons to understand the mechanisms that control core motion. Keeping tabs
on these small shifts helps keep technology safe and adds to our knowledge of
Earth’s internal workings.
According to Elisabetta Iorfida, ESA’s Swarm Mission Scientist, the Pacific
reversal challenges assumptions that the outer core is dominated by stable
westward circulation. She noted, “This study shows that regional changes can
emerge rapidly within just a decade. The findings may also help scientists
investigate possible interactions between Earth’s outer core, inner core,
lower mantle, and, therefore, give more insights into the core-mantle
boundary, which is a critical region for the deep Earth dynamics.”
“This research raises intriguing questions about how Earth’s deepest layers
are dynamically connected. As the magnetic field continues to evolve,
satellite missions are providing an increasingly detailed view of the dynamic
processes unfolding deep inside our planet, revealing that Earth’s core may
be far more variable and complex than once believed.”
然而，磁场并非一成不变。随着时间的推移，地核流动模式的演变会导致磁场缓慢变化，
进而降低导航系统的精确度，使太空船通讯失效，并影响近地空间天气模型的预测。因此
，无论从科学、技术或社会角度来看，了解控制地核运动的机制都至关重要。密切注意这
些微小的变化有助于保障科技安全，并增进我们对地球内部运作机制的了解。
欧洲太空总署“蜂群”任务科学家伊丽莎白·伊奥尔菲达表示，太平洋环流反转挑战了外
核主要由稳定的西向环流主导的假设。她指出：“这项研究表明，区域性变化可以在短短
十年内迅速出现。研究结果还有助于科学家探究地球外核、内核和下地幔之间可能存在的
相互作用，从而更深入地了解核幔边界—这是地球深部动力学的关键区域。”
“这项研究引发了关于地球最深层如何动态连接的有趣问题。随着磁场的不断演变，卫星
任务正在提供越来越详细的地球内部动态过程图像，揭示出地球核心可能比我们之前认为
的更加多变和复杂。”
