Ngo-Ephreli 25, embikweni okhishwe yi-Brazilian National Meteorological Institute (Inmet), kwethulwa ukuhlaziywa okuphelele kokungafani kwesimo sezulu kanye nezimo zezulu ezimbi kakhulu ezibangelwe yi-El Nino eBrazil ngo-2023 kanye nezinyanga ezintathu zokuqala zika-2024.
Umbiko uphawule ukuthi isimo sezulu se-El Nino siphinde kabili imvula eningizimu yeBrazil, kodwa kwezinye izindawo, imvula ibingaphansi kakhulu kwesilinganiso. Ochwepheshe bakholelwa ukuthi isizathu ukuthi phakathi kuka-Okthoba ngonyaka odlule noMashi kulo nyaka, isimo se-El Nino sibangele ukuthi kube neziwombe eziningana zamagagasi okushisa angene ezifundeni ezisenyakatho, eziphakathi nezisentshonalanga yeBrazil, okwanciphisa inqubekela phambili yezinqwaba zomoya obandayo (iziphepho kanye nezimbobo ezibandayo) kusukela eningizimu yeNingizimu Melika kuya enyakatho. Eminyakeni edlule, inqwaba yomoya obandayo enjalo yayiya enyakatho esigodini soMfula i-Amazon futhi ihlangane nomoya oshisayo ukuze yakhe imvula enkulu, kodwa kusukela ngo-Okthoba 2023, indawo lapho kuhlangana khona umoya obandayo noshisayo iye yaqhubekela esifundeni esiseningizimu yeBrazil esingamakhilomitha angu-3,000 ukusuka esigodini soMfula i-Amazon, futhi kuye kwavela iziwombe eziningana zemvula enkulu endaweni yasendaweni.
Lo mbiko uphinde uveze ukuthi omunye umphumela obalulekile we-El Nino eBrazil ukwanda kwezinga lokushisa kanye nokufuduka kwezindawo zokushisa eziphakeme. Kusukela ngo-Okthoba ngonyaka odlule kuya kuMashi kulo nyaka, amarekhodi okushisa aphezulu kakhulu emlandweni wesikhathi esifanayo aphulwe kulo lonke elaseBrazil. Kwezinye izindawo, izinga lokushisa eliphakeme kakhulu lalingama-degree Celsius angu-3 kuya kwangu-4 ngaphezu kwenani eliphakeme kakhulu. Phakathi naleso sikhathi, amazinga okushisa aphezulu kakhulu enzeka ngoDisemba, entwasahlobo yaseningizimu yeNkabazwe, kunokuba kube ngoJanuwari nangoFebhuwari, izinyanga zasehlobo.
Ngaphezu kwalokho, ochwepheshe bathi amandla e-El Nino anciphile kusukela ngoDisemba ngonyaka odlule. Lokhu kuchaza nokuthi kungani intwasahlobo ishisa kakhulu kunehlobo. Idatha ikhombisa ukuthi izinga lokushisa elijwayelekile ngoDisemba 2023, ngesikhathi sentwasahlobo yaseNingizimu Melika, lishisa kakhulu kunezinga lokushisa elijwayelekile ngoJanuwari nangoFebhuwari 2024, ngesikhathi sehlobo laseNingizimu Melika.
Ngokusho kochwepheshe besimo sezulu baseBrazil, amandla e-El Nino azoncipha kancane kancane kusukela ekupheleni kwekwindla kuya ekuqaleni kobusika kulo nyaka, okungukuthi, phakathi kukaMeyi noJulayi 2024. Kodwa ngokushesha ngemva kwalokho, ukwenzeka kweLa Nina kuzoba yisenzakalo esingenzeka kakhulu. Izimo zaseLa Nina kulindeleke ukuthi ziqale engxenyeni yesibili yonyaka, kanti amazinga okushisa omhlaba emanzini ashisayo ePacific ephakathi nasempumalanga ehla kakhulu ngaphansi kwesilinganiso.
