Kodi Tanthauzo la El Nino Ndi Chiyani?
El Nino, yemwe m'Chisipanishi amamasulira kuti "kamnyamata" kapena "mwana wa Khristu", adapatsidwa dzina ndi asodzi a ku South America omwe adawona kutentha kwa madzi a Pacific Ocean mu Disembala. Koma musasocheretsedwe ndi dzina lake - El Nino ndi yaying'ono!
Ndiye chimayambitsa El Nino ndi chiyani? Kugwirizana kwa El Nino pakati pa nyanja ndi mlengalenga kumapangitsa kutentha kwapanyanja pakati ndi kum'maŵa kwapakati pa Equatorial Pacific kuchulukirachulukira, zomwe zimapangitsa kuti mpweya wokhala ndi chinyezi uwonjezeke kukhala mvula yamkuntho.
M’zaka za m’ma 1930, asayansi monga Sir Gilbert Walker anatulukira zinthu zododometsa: El Nino ndi Southern Oscillation zinali kuchitika nthawi imodzi!
The Southern Oscillation ndi njira yachilendo yonenera kuti kuthamanga kwa mpweya pamwamba pa nyanja ya Pacific Ocean kumasintha.
Kum'maŵa kwa Pacific kotentha kukawotcha (chifukwa cha El Nino), kuthamanga kwa mpweya pamwamba pa nyanja kumatsika. Zochitika ziwirizi ndizolumikizana kwambiri kotero kuti akatswiri azanyengo adazipatsa dzina lokopa: El Nino-Southern Oscillation, kapena ENSO mwachidule. Masiku ano, akatswiri ambiri amagwiritsa ntchito mawu akuti El Nino ndi ENSO mosiyana.

Kodi Chimachitika Chiyani Panthawi ya El Nino?
Chochitika cha El Nino chikachitika, mphepo zamalonda zomwe nthawi zambiri zimawomba chakumadzulo motsatira Equator zimayamba kufooka. Kusintha kumeneku kwa kuthamanga kwa mpweya ndi liwiro la mphepo kumapangitsa kuti madzi ofunda a pamwamba asunthire chakum’mawa motsatira Equator, kuchokera kumadzulo kwa Pacific kupita kugombe la kumpoto kwa South America.
Madzi ofunda amenewa akamayenda, amakulitsa thermocline, komwe ndi kuzama kwa nyanja komwe kumalekanitsa madzi apansi ofunda ndi ozizira pansi. Panthawi ya El Nino, thermocline imatha kuviika mpaka mamita 152 (mamita 500)!
Madzi ofunda okhuthala amenewa amawononga kwambiri zachilengedwe za m’mphepete mwa nyanja kum’mawa kwa Pacific. Popanda madzi ozizira omwe ali ndi michere yambiri, malo osangalalira sangathenso kuthandizira chilengedwe chake chomwe chimabala zipatso. Nsomba zambiri zimafa kapena kusamuka, zomwe zikuwononga chuma cha Ecuador ndi Peru.
Koma si zokhazo! El Nino imayambitsanso kufalikira komanso nthawi zina kusintha kwakukulu kwa nyengo. Kuyenda pamwamba pa madzi ofunda kumabweretsa mvula yambiri, zomwe zimapangitsa kuti mvula iwonjezeke ku Ecuador ndi kumpoto kwa Peru. Izi zingapangitse kusefukira kwa madzi ndi kukokoloka kwa nyanja, kuwononga nyumba, sukulu, zipatala, ndi malonda. Mayendedwe ndi ochepa ndipo mbewu zimawonongeka.
El Nino imabweretsa mvula ku South America koma chilala ku Indonesia ndi Australia, zomwe zimasokoneza madzi awo pamene nkhokwe zimauma komanso mitsinje imanyamula zochepa. Ulimi womwe umadalira ulimi wothirira nawonso ukhoza kukhala pachiwopsezo ndi El Nino! Chifukwa chake konzekerani ndikukonzekera mphamvu zake zosayembekezereka komanso zamphamvu!
Kodi El Nino Ndi Yabwino Kapena Yoipa?
El Nino amakonda kubweretsa nyengo yotentha komanso yowuma yomwe imapangitsa kuti chimanga chizikula ku US Komabe, ku Southern Africa ndi Australia, zitha kubweretsa mikhalidwe yowuma yomwe imawonjezera ngozi zamoto, pomwe Brazil ndi kumpoto kwa South America zimakhala zowuma ndipo Argentina ndi Chile amawona mvula. . Chifukwa chake konzekerani mphamvu zosayembekezereka za El Nino momwe zimatipangitsa kulingalira!
Kodi El Nino Imakhala Nthawi Yaitali Bwanji?
Gwirani zipewa zanu, owonera nyengo: nayi kutsika kwa El Nino! Nthawi zambiri, gawo la El Nino limatha miyezi 9-12. Nthawi zambiri imayamba mu kasupe (March-June), imafika pachimake pakati pa miyezi yophukira-yozizira (November-February), ndiyeno imafooka kumayambiriro kwa miyezi ya chilimwe monga March-June.
Ngakhale zochitika za El Nino zimatha kupitilira chaka chimodzi, makamaka zimachitika miyezi isanu ndi inayi mpaka 12 - El Nino yayitali kwambiri m'mbiri yamakono idatenga miyezi 18 yokha. El Nino amabwera zaka ziwiri kapena zisanu ndi ziwiri zilizonse (quasi-periodic), koma sizikuchitika nthawi zonse.
Kodi Tinganene Kuti El Nino Isanachitike?
Inde! Ukadaulo wamakono watidabwitsa tikamaneneratu za El Nino.
Chifukwa cha zitsanzo za nyengo ngati zomwe zimagwiritsidwa ntchito ndi NOAA's National Centers for Environmental Prediction ndi deta yochokera ku Tropical Pacific Observing System sensors pa satellites, ocean buoys, ndi ma radiosondes omwe amawunikira kusintha kwa nyengo - asayansi nthawi zambiri amatha kulosera molondola kuti idzafika miyezi kapena zaka zisanachitike.
Popanda zida zotere sitingakhale ndi njira yodziwira zomwe zikubwera pokhudzana ndi zovuta zanyengo monga El Nino.
Kodi El Ninos Akukula Kwambiri?
Zitsanzo za nyengo zimapanga projekiti yomwe Dziko likamatentha kwambiri, kuzungulira kwa ENSO kumatha kukulirakulira ndikutulutsa ma El Ninos ndi La Ninas owopsa omwe atha kuwononga madera padziko lonse lapansi. Koma si zitsanzo zonse zimene zimagwirizana, ndipo asayansi akugwira ntchito mwakhama kuti adziwe zambiri zokhudza nkhaniyi.
Mutu umodzi womwe udakali wokambitsirana ndi ngati kuzungulira kwa ENSO kwakula kale chifukwa cha kusintha kwa nyengo komwe kumachitika chifukwa cha anthu, ngakhale chinthu chimodzi chikadali chotsimikizika - ENSO yakhalapo kwa zaka masauzande ambiri ndipo mwina ipitilirabe mpaka mtsogolo.
Ngakhale kuti kuzungulira kwake sikunasinthe, zotsatira zake zikhoza kuonekera kwambiri pamene Dziko lapansi likupitirizabe kutentha.

Mafunso Ofunsidwa Kawirikawiri
El Niño ndi La Niña amatanthauza chiyani?
El Nino ndi La Nina ndi mitundu iwiri ya nyengo yomwe imapezeka ku Pacific Ocean. Iwo ndi gawo la kuzungulira kotchedwa El Niño/Southern Oscillation (ENSO).
El Nino amachitika pamene madzi a kum’maŵa chapakati pa Pacific Ocean amafunda kuposa masiku onse, zomwe zimachititsa kusintha kwa nyengo monga kutentha kwapamwamba ndi kusintha kwa mvula. Chodabwitsa ichi chikuwonetsa gawo lofunda la kuzungulira kwa ENSO.
La Nina imachitika pamene madzi a m’dera lomwelo la nyanja ya Pacific akuzizira mocheperapo, kusinthasintha nyengo mwa kutulutsa kutentha kozizira ndi kusinthasintha kwa mvula; imawonetsa gawo lozizira mumayendedwe a ENSO.
Kodi El Niño amatanthauza kuzizira?
El Nino amatha kudziwika ndi kutentha kwa nyanja ku Equatorial Pacific pamene La Nina imadziwika ndi madzi ozizira modabwitsa m'dera lomweli.
N’chifukwa chiyani El Niño amatchedwa mwana wodalitsika?
Mawu a Chisipanishi akuti El Niño, omwe amatanthauza "mwana wamwamuna," poyamba ankagwiritsidwa ntchito ndi asodzi ku Ecuador ndi Peru kufotokoza kutentha kwa madzi a m'mphepete mwa nyanja kumene kumachitika nthawi ya Khirisimasi.
Poyamba, ankanena za zochitika zokhazikika za nyengo. Komabe, m'kupita kwa nthawi, dzinali linayamba kuimira kutentha kwakukulu ndipo tsopano likutanthauza nyengo yofunda kwambiri yomwe imachitika zaka zingapo zilizonse.
