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.
在我們腳下約2200公里處是地核，這是一層不斷移動的熔融岩石層。這種旋轉產生了地球
的天然磁場。幾十年來，科學家觀測到地核主要向西旋轉。但在2010年，一件奇特的事情
發生了：太平洋下方的地核流動方向突然逆轉，開始向東湧動。這種反轉的原因至今仍不
清楚。
借助歐洲太空總署的 Swarm 和 CryoSat 等衛星，研究人員收集了地球磁場強度微小變化
的詳細測量數據。
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.
研究團隊分析了近30年（1997-2025年）間由地面站和衛星任務收集的數據，其中包括歐
洲太空總署的Swarm和CryoSat衛星、德國的CHAMP衛星以及丹麥的Ørsted衛星。研究結果
對長期以來關於地核外層穩定的假設提出了質疑。
這種逆轉顯示地球深處正在發生劇烈的變化，讓我們得以窺見磁場形成的新線索。它也暗
示著外核的變化與地球深處的變化之間可能存在著先前未被發現的關聯。
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.
該研究的第一作者、愛丁堡大學地球科學學院的弗雷德里克·達爾·馬德森表示：“太平
洋下方的大規模環流逆轉引發了關於地球深部內部行為的新問題。科學家們現在想要了解
，這種逆轉究竟代表短暫的波動、週期性振蕩的一部分，還是地核環流的一種新的穩定平
衡狀態。持續監測對於確定未來幾年環流的演變至關重要。”
地磁發電機是由外核中熔融鐵圍繞固態內核的循環所驅動的，正是這種循環維持著地球磁
場。儘管這種循環具有高度動態性，但其大部分主要流動模式在數十年間都保持穩定。
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，歐洲太空總署發射了三顆「群星」（Swarm）衛星，每顆衛星都攜帶超靈敏的磁
力計。這些衛星在精確協調的軌道上飛行，能夠將源自地核的磁訊號與源自地殼、海洋、
大氣層和太空的磁訊號區分開來。
這種精確度使得科學家能夠拼湊出地核-地函邊界處流體隨時間的演變過程。這些重建結
果也揭示了一些意想不到的現象，例如2010年的太平洋磁極反轉和2017年的劇烈“地磁突
變”，這些都表明地球深部內部能夠發生快速且不可預測的變化。
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.
據歐洲太空總署「蜂群」任務經理安雅·斯特羅姆稱，「蜂群」提供的長期數據集對這項
研究至關重要。她指出：“儘管‘蜂群’是在2010年劇烈的逆轉事件之後發射的，但它提
供了高精度數據，讓我們了解了此後一段時間內地球內核的情況。”
更廣泛的數據集還揭示了隱藏在精度較低的記錄中的更微妙的、波動性的加速度變化和快
速的流速變化。這項研究表明，太平洋下方的東向流動可能正在減弱，這預示著地球深部
內部更大幅度的振盪或更長週期的週期可能正在減速。
地球的核心是外層翻騰的熔融鐵，地球磁場的大部分就源自於此，它保護我們免受太陽輻
射粒子的侵害。如果沒有這層屏蔽層，大氣層和我們的科技系統將更容易受到來自太陽的
有害輻射的侵害。
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，磁場並非一成不變。隨著時間的推移，地核流動模式的演變會導致磁場緩慢變化，
進而降低導航系統的精確度，使太空船通訊失效，並影響近地空間天氣模型的預測。因此
，無論從科學、技術或社會角度來看，了解控制地核運動的機制都至關重要。密切注意這
些微小的變化有助於保障科技安全，並增進我們對地球內部運作機制的了解。
歐洲太空總署「蜂群」任務科學家伊麗莎白·伊奧爾菲達表示，太平洋環流反轉挑戰了外
核主要由穩定的西向環流主導的假設。她指出：“這項研究表明，區域性變化可以在短短
十年內迅速出現。研究結果還有助於科學家探究地球外核、內核和下地幔之間可能存在的
相互作用，從而更深入地了解核幔邊界—這是地球深部動力學的關鍵區域。”
「這項研究引發了關於地球最深層如何動態連接的有趣問題。隨著磁場的不斷演變，衛星
任務正在提供越來越詳細的地球內部動態過程圖像，揭示出地球核心可能比我們之前認為
的更加多變和復雜。”
