X'inhu t-tifsira ta' 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)Fis-snin tletin, xjenzati bħal Sir Gilbert Walker għamlu skoperta ta’ xedaq: El Nino u l-Oxxillazzjoni tan-Nofsinhar kienu qed iseħħu fl-istess ħin!
L-Oxxillazzjoni tan-Nofsinhar huwa mod fancy kif tgħid li l-pressjoni tal-arja fuq l-Oċean Paċifiku tropikali tinbidel.
Meta l-Paċifiku tropikali tal-Lvant jisħon (grazzi għal El Nino), il-pressjoni tal-arja fuq l-oċean tonqos. Dawn iż-żewġ fenomeni huma tant interkonnessi li l-klimatologi tawhom isem li jaqbad: El Nino-Southern Oscillation, jew ENSO fil-qosor. Illum il-ġurnata, ħafna mill-esperti jużaw it-termini El Nino u ENSO b'mod interkambjabbli.

X'jiġri Waqt El Nino?
Meta jseħħ avveniment ta 'El Nino, l-irjieħ tal-kummerċ li normalment jonfħu lejn il-punent tul l-Ekwatur jibdew jiddgħajfu. Din il-bidla fil-pressjoni tal-arja u l-veloċità tar-riħ tikkawża li l-ilma tal-wiċċ sħun jimxi lejn il-lvant tul l-Ekwatur, mill-Punent tal-Paċifiku sal-kosta tat-tramuntana tal-Amerika t'Isfel.
Hekk kif dan l-ilma sħun jiċċaqlaq, japprofondixxi t-thermocline, li huwa s-saff tal-fond tal-oċean li jifred l-ilma sħun tal-wiċċ mill-ilma kiesaħ taħt. Waqt avveniment ta 'El Nino, it-thermocline jista' dip sa 152 metru (500 pied)!
Meta El Nino jolqot, partijiet mill-Amerika ta’ Fuq jistgħu jiffaċċjaw xtiewi itwal u kesħin mis-soltuDan is-saff oħxon ta’ ilma sħun għandu impatt devastanti fuq l-ekosistema kostali tal-Paċifiku tal-Lvant. Mingħajr l-upwelling normali ta 'ilma kiesaħ b'ħafna nutrijenti, iż-żona ewfotika ma tistax tibqa' tappoġġja l-ekosistema normalment produttiva tagħha. Il-popolazzjonijiet tal-ħut imutu jew jemigraw, u jġiegħlu ħerba fl-ekonomiji tal-Ekwador u l-Perù.
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.
El Nino iġib ix-xita fl-Amerika t'Isfel iżda n-nixfa fl-Indoneżja u l-Awstralja, li thedded il-provvisti tal-ilma tagħhom hekk kif il-ġibjuni jinxfu u x-xmajjar iġorru inqas. L-agrikoltura li tiddependi fuq l-irrigazzjoni tista' wkoll titqiegħed f'riskju minn El Nino! Allura ipprepara lilek innifsek u ħeġġu infuskom għall-forza imprevedibbli u qawwija tagħha!
El Nino huwa Tajjeb jew Ħażin?
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!
Kemm idum Tipikament 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.
Nistgħu Nbassru El Nino Qabel Jiġri?
Iva! It-teknoloġija moderna għaġbitna meta niġu biex inbassru 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.
Mingħajr għodod bħal dawn ma kien ikollna l-ebda mod kif inkunu nafu x’qed ġejna f’termini ta’ kumplikazzjonijiet tat-temp bħal El Nino.
Qed Isir El Ninos aktar b'saħħtu?
Il-mudelli tal-klima jipproġettaw li hekk kif id-Dinja tissaħħan aktar, iċ-ċikli ENSO jistgħu jintensifikaw akbar u jipproduċu El Ninos u La Ninas saħansitra aktar estremi li jistgħu jkollhom impatti devastanti fuq il-komunitajiet madwar id-dinja. Iżda mhux il-mudelli kollha jaqblu, u x-xjenzati qed jaħdmu bla heda biex jiksbu aktar għarfien dwar dan il-fenomenu kumpless.
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.
Anke jekk iċ-ċiklu attwali tiegħu jibqa' l-istess, l-effetti tiegħu jistgħu jsiru dejjem aktar evidenti hekk kif id-Dinja tkompli tissaħħan.

Xi jfissru El Niño u La Niña?
El Nino u La Nina huma żewġ mudelli tat-temp li jinsabu fl-Oċean Paċifiku. Huma parti minn ċiklu msejjaħ El Niño/Oxxillazzjoni tan-Nofsinhar (ENSO).
El Nino iseħħ meta l-ilma fl-Oċean Paċifiku tal-Lvant u ċentrali jsir aktar sħun mis-soltu, u dan iwassal għal bidliet fix-xejriet tat-temp bħal temperaturi ogħla u xejriet ta’ xita mibdula. Dan il-fenomenu jimmarka l-fażi sħuna taċ-ċiklu ENSO.
La Nina sseħħ meta l-ilma fl-istess parti tal-Oċean Paċifiku jibred taħt in-normal, jibdel it-temp billi jipproduċi temperaturi aktar friski u jbiddel ix-xejriet tax-xita; timmarka fażi kiesħa fiċ-ċiklu ENSO.
El Niño ifisser kesħin?
El Nino jista’ jiġi identifikat minn temperaturi tal-baħar sħan anormalment fil-Paċifiku Ekwatorjali filwaqt li La Nina hija kkaratterizzata minn ilmijiet kesħin mhux tas-soltu f’dan l-istess reġjun.
Għala El Niño jissejjaħ tifel imbierek?
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.
Inizjalment, irreferiet għal okkorrenza staġjonali regolari. Madankollu, maż-żmien, l-isem beda jirrappreżenta xejra ta 'tisħin usa' u issa jirreferi għall-mudelli ta 'temp mhux tas-soltu sħun li jseħħu kull ftit snin.
