O le a le uiga o le El Nino?
El Nino, which in Spanish translates to "little boy" or "Christ child", was given its name by South American fishermen who observed a warming of Pacific Ocean waters during December. But don't be misled by its name - El Nino is anything but small!
So what causes El Nino? El Nino's interaction between the ocean and atmosphere causes sea surface temperatures in central and east-central Equatorial Pacific to increase, which causes moisture-rich air to accelerate into rainstorms.
El Nino meaning - What would happen between a normal year and El Nino Year (Image source: Spudman)I le vaitau o le 1930, na faia ai e saienitisi e pei o Sir Gilbert Walker se suʻesuʻega mataʻutia: El Nino ma le Southern Oscillation na tupu i le taimi e tasi!
O le Southern Oscillation ose auala matagofie e fai mai ai e suia le mamafa o le ea i luga o le vasa Pasefika.
A vevela le Pasefika i sasae (fa'afetai i le El Nino), e pa'ū le mamafa o le ea i luga o le sami. O nei mea mata'utia e lua e matua'i feso'ota'i ma o lea na faaigoa ai e tagata su'esu'e i le tau le igoa: El Nino-Southern Oscillation, po'o le ENSO mo se faapuupuuga. I aso nei, o le tele o tagata atamamai latou te faʻaogaina upu El Nino ma ENSO e fesuiaʻi.

O le a le mea e tupu i le taimi o El Nino?
A tupu se El Nino, e amata ona vaivai le matagi e masani ona agi agai i sisifo i le Ekueta. O lenei suiga i le mamafa o le ea ma le saoasaoa o le savili e mafua ai ona agai i sasae le vai mafanafana i luga o le Ekueta, mai le Pasefika i sisifo i le talafatai i matu o Amerika i Saute.
A o gaioi lenei vai mafanafana, e faalolotoina ai le thermocline, o le vaega lea o le loloto o le sami lea e vavaeeseina ai le vai mafanafana mai le vai malulu i lalo. I le taimi o le El Nino, e mafai ona goto le thermocline i le 152 mita (500 futu)!
A o'o mai El Nino, o vaega o Amerika i Matu e ono umi atu, malulu malulu nai lo le masaniO lenei vaega mafiafia o vai mafanafana o lo'o i ai se aafiaga fa'aleagaina i le gataifale o le Pasefika i sasae. A aunoa ma le fa'afefeteina masani o le vai malulu, e le mafai e le sone euphotic ona lagolagoina lona fa'anatura masani. E feoti pe feoa'i le faitau aofa'i o i'a, ma fa'aleagaina ai le tamaoaiga o Ekuatoa ma Peru.
But that's not all! El Nino also causes widespread and sometimes severe changes in the climate. Convection above the warmer surface waters brings increased precipitation, leading to drastic increases in rainfall in Ecuador and northern Peru. This can contribute to coastal flooding and erosion, destroying homes, schools, hospitals, and businesses. Transportation is limited and crops are destroyed.
O le El Nino e aumai ai timuga i Amerika i Saute ae o le lamala i Initonesia ma Ausetalia, lea e lamatia ai a latou sapalai o vai pe a mamago faatanoa ma itiiti vaitafe. O fa'ato'aga e fa'alagolago i vai e mafai fo'i ona lamatia e El Nino! O lea ia saunia oe lava ma sauni oe lava mo lona malosi le mafaamatalaina ma le malosi!
E lelei pe leaga El Nino?
El Nino tends to bring warmer and drier conditions that boost corn production in the U.S. However, in Southern Africa and Australia, it can bring dangerously dry conditions that increase fire risks, while Brazil and northern South America experience dry spells and Argentina and Chile see rainfall. So get ready for El Nino's unpredictable power as it keeps us guessing!
O le a le umi e masani ai le El Nino?
Hold onto your hats, weather watchers: here's the lowdown on El Nino! Typically, an El Nino episode lasts 9-12 months. It usually develops in spring (March-June), reaches peak intensity between late autumn/winter months (November-February), and then weakens in early summer months like March-June.
Though El Nino events may last more than one year, mostly they occur about nine to 12 months in duration - the longest El Nino in modern history only lasted 18 months. El Nino comes every two or seven years (quasi-periodic), but it's not happening on a regular schedule.
E mafai ona tatou vavalo le El Nino ae le'i tupu?
Ioe! O tekinolosi fa'aonaponei ua maofa ai i tatou pe a o'o mai i le vavalo o El Nino.
Thanks to climate models like those employed by NOAA's National Centers for Environmental Prediction and data from Tropical Pacific Observing System sensors on satellites, ocean buoys, and radiosondes monitoring changing weather conditions - scientists can often accurately forecast its arrival months or years beforehand.
A aunoa ma ia meafaigaluega semanu tatou te le iloa le mea o loʻo oʻo mai ia i tatou i tulaga o faʻalavelave tau e pei ole El Nino.
O Fa'amalolosi El Ninos?
Fa'ata'ita'iga fa'ata'ita'iga o le tau e fa'apea, a'o fa'a mafanafana atili le lalolagi, e ono fa'ateteleina ta'amilosaga ENSO ma fa'atupu ai le tele o El Ninos ma La Ninas e ono fa'aleagaina ai nu'u i le lalolagi atoa. Ae le o faʻataʻitaʻiga uma e ioe, ma o saienitisi o loʻo galulue ma le le vaivai e maua atili le malamalama i lenei faʻalavelave lavelave.
One topic still up for debate is whether ENSO's cycle has already intensified as a result of human-caused climate change, though one thing remains certain - ENSO has existed for thousands of years and will likely persist far into the future.
E tusa lava pe tumau pea le le suia o lona taamilosaga, o ona aafiaga e mafai ona faʻateleina ona iloa aʻo faʻaauau pea le mafanafana o le lalolagi.

The Spanish term El Niño, meaning "the son," was originally used by fishermen in Ecuador and Peru to describe the warming of coastal surface waters that typically happens around Christmas.
