'New El Niño' discovered south of the equator
by University of Reading

A small area of the southwestern Pacific Ocean, near New Zealand and
Australia, can trigger temperature changes that affect the entire Southern
Hemisphere, a new study has found.

赤道以南發現「新聖嬰」現象
雷丁 大學

一項新研究發現，西南太平洋靠近紐西蘭和澳洲的一小片區域可能引發影響整個南半球的
溫度變化。

The new climate pattern, which shares some characteristics with the El Niño
phenomenon, has been named the "Southern Hemisphere Circumpolar Wavenumber-4
Pattern."

Unlike El Niño, which starts in the tropics, this new pattern begins in the
mid-latitudes. The study, published this month in the Journal of Geophysical
Research: Oceans, highlights how important the interaction between the ocean
and atmosphere is for our climate.

這種新的氣候模式與厄爾尼諾現像有一些共同特徵，被命名為「南半球繞極波數4模式」
。



Balaji Senapati, lead author of the study at the University of Reading, said,
"This discovery is like finding a new switch in Earth's climate. It shows
that a relatively small area of the ocean can have wide-reaching effects on
global weather and climate patterns.

"Understanding this new weather system could greatly improve weather
forecasting and climate prediction, especially in the Southern Hemisphere. It
might help explain climate changes that were previously mysterious and could
improve our ability to predict extreme weather and climate events."



“了解這個新的天氣系統可以極大地改善天氣預報和氣候預測，特別是在南半球。它可能
有助於解釋以前神秘的氣候變化，並可以提高我們預測極端天氣和氣候事件的能力。”

Hidden in plain sight

Researchers used sophisticated climate models to simulate 300 years of
climate conditions. This model combines atmospheric, oceanic, and sea-ice
components to create a comprehensive representation of Earth's climate
system. By analyzing this simulated data, the team identified a recurring
pattern of sea surface temperature variations circling the Southern
Hemisphere.

隱藏在眾目睽睽之下



The weather pattern works like a global chain reaction. This pattern creates
four alternating warm and cool areas in the oceans, forming a complete circle
in the Southern Hemisphere. It starts near the ocean of New Zealand and
Australia. When the ocean temperature changes in this small area, it triggers
a ripple effect in the atmosphere. This creates a wave-like pattern that
travels around the entire Southern Hemisphere, carried by strong westerly
winds.

As this atmospheric wave moves, it affects ocean temperatures, creating the
four warm and cool areas.



當大氣波移動時，它會影響海洋溫度，形成四個溫暖和涼爽的區域。

The ocean plays a big role in this process. When the atmospheric wave changes
wind patterns, it affects how heat moves between the ocean and air. This
changes the depth of the ocean's upper layer of warmer water, which can make
temperature changes stronger or weaker.

海洋在這個過程中扮演著重要角色。當大氣波改變風型時，它會影響熱量在海洋和空氣之
間的移動方式。這會改變海洋上層較暖水的深度，使溫度變化更強或更弱。

This new pattern happens independently of other known weather systems in the
tropics, such as the warming El Niño pattern of currents and trade winds, or
its opposite, cooling phase, La Niña. This suggests it has always been a
part of Earth's climate, but it has only just been noticed.
