Ngomhla wama-25 ku-Epreli, kwingxelo ekhutshwe yiBrazilian National Meteorological Institute (Inmet), kuchazwe uhlalutyo olupheleleyo lwezinto ezingaqhelekanga zemozulu kunye neemeko zemozulu ezimbi kakhulu ezibangelwe yi-El Nino eBrazil ngo-2023 kunye neenyanga ezintathu zokuqala zika-2024.
Ingxelo iphawule ukuba imozulu ye-El Nino iphindaphinde kabini imvula emazantsi eBrazil, kodwa kwezinye iindawo, imvula ibingaphantsi komndilili. Iingcali zikholelwa ukuba isizathu kukuba phakathi kuka-Okthobha kunyaka ophelileyo noMatshi kulo nyaka, imbonakalo ye-El Nino ibangele ukuba kubekho imijikelo emininzi yamaza obushushu angene kwimimandla esemantla, embindini nasentshona yeBrazil, nto leyo eyathintela inkqubela yomoya obandayo (iinkanyamba kunye nemida ebandayo) ukusuka kwincam esemazantsi yeMzantsi Melika ukuya emantla. Kwiminyaka edlulileyo, umoya obandayo onjalo ubuya emantla uye kwi-Amazon River Basin uze udibane nomoya oshushu ukuze wenze imvula enkulu, kodwa ukusukela ngo-Okthobha ka-2023, indawo apho umoya obandayo noshushu udibana khona iye yanda ukuya kummandla osemazantsi eBrazil kwiikhilomitha ezingama-3,000 ukusuka kwi-Amazon River Basin, kwaye kuye kwenziwa imijikelo emininzi yemvula enkulu kwindawo yasekuhlaleni.
Ingxelo ikwabonisa ukuba enye impembelelo ebalulekileyo ye-El Nino eBrazil kukunyuka kwamaqondo obushushu kunye nokufuduka kweendawo ezinamaqondo obushushu aphezulu. Ukususela ngo-Okthobha kunyaka ophelileyo ukuya kuMatshi kulo nyaka, iirekhodi zobushushu eziphezulu kwimbali yexesha elifanayo ziye zaphulwa kulo lonke elaseBrazil. Kwezinye iindawo, amaqondo obushushu aphezulu ayengama-3 ukuya kuma-4 degrees Celsius ngaphezu kwencopho yerekhodi. Okwangoku, amaqondo obushushu aphezulu enzeka ngoDisemba, intwasahlobo esemazantsi e-Hemisphere, endaweni kaJanuwari noFebruwari, iinyanga zasehlotyeni.
Ukongeza, iingcali zithi amandla e-El Nino ehlile ukusukela ngoDisemba kunyaka ophelileyo. Oku kukwachaza isizathu sokuba intwasahlobo ishushu kakhulu kunehlobo. Idatha ibonisa ukuba ubushushu obuqhelekileyo ngoDisemba ka-2023, ngexesha lentwasahlobo yaseMzantsi Melika, bushushu ngakumbi kuneqondo lobushushu eliqhelekileyo ngoJanuwari nangoFebruwari ka-2024, ngexesha lehlobo laseMzantsi Melika.
Ngokutsho kweengcali zemozulu zaseBrazil, amandla e-El Nino aza kuyehla kancinci kancinci ukususela ekupheleni kwekwindla ukuya ekuqaleni kobusika kulo nyaka, oko kukuthi, phakathi kukaMeyi noJulayi 2024. Kodwa emva koko, ukwenzeka kweLa Nina kuza kuba yinto enokwenzeka kakhulu. Kulindeleke ukuba iimeko zaseLa Nina ziqale kwisiqingatha sesibini sonyaka, apho amaqondo obushushu omhlaba emanzini ashushu kumbindi wePasifiki nasempuma ehla kakhulu ngaphantsi komndilili.
