Ngomhla zingama-25 kuMbasa, embikweni okhishwe yi-Brazilian National Meteorological Institute (Inmet), ukuhlaziya okuphelele kokungahambi kahle kwesimo sezulu kanye nezimo zezulu ezimbi kakhulu ezabangelwa u-El Nino eBrazil ngo-2023 kanye nezinyanga ezintathu zokuqala zika-2024.
Umbiko uveze ukuthi isimo sezulu sika-El Nino sesiye sanetha kabili imvula eningizimu yeBrazil, kodwa kwezinye izindawo, imvula ibingaphansi kwesilinganiso.Ochwepheshe bakholelwa ukuthi isizathu siwukuthi phakathi kuka-Okthoba wonyaka odlule no-March walo nyaka, isenzakalo sika-El Nino sabangela imizuliswano eminingana yokushisa kwamagagasi okushisa angena ezindaweni ezisenyakatho, emaphakathi nesentshonalanga yeBrazil, okwanciphisa inqubekelaphambili yobuningi bomoya obandayo (iziphepho namakhaza). fronts) ukusuka endaweni eseningizimu yeNingizimu Melika ukuya enyakatho.Eminyakeni edlule, umoya obandayo onjalo ubungaya enyakatho emfuleni i-Amazon futhi uhlangane nomoya oshisayo ukuze kwakhe imvula enkulu, kodwa kusukela ngo-October 2023, indawo lapho kuhlangana khona umoya obandayo noshisayo iye yadlulela esifundeni esiseningizimu ye- I-Brazil eqhele ngamakhilomitha angu-3,000 ukusuka esigodini soMfula i-Amazon, futhi kuye kwakhiwa imijikelezo eminingana yemvula enkulu endaweni yangakini.
Lo mbiko uphinde uveze ukuthi omunye umphumela obalulekile we-El Nino eBrazil ukwanda kwezinga lokushisa kanye nokugudluzwa kwezindawo zokushisa eziphakeme.Kusukela ngo-Okthoba wonyaka odlule kuya kuNdasa kulo nyaka, amarekhodi okushisa aphezulu kakhulu emlandweni wenkathi efanayo aphuliwe kulo lonke elaseBrazil.Kwezinye izindawo, izinga lokushisa eliphezulu lalingu-3 kuya ku-4 degrees Celsius ngaphezu kwerekhodi eliphakeme.Phakathi naleso sikhathi, amazinga okushisa aphakeme kakhulu enzeka ngoDisemba, intwasahlobo eseningizimu Nenkabazwe, kunoJanuwari noFebruwari, izinyanga zasehlobo.
Ngaphezu kwalokho, ongoti bathi amandla e-El Nino ehlile kusukela ngoDisemba nyakenye.Lokhu kuphinde kuchaze ukuthi kungani intwasahlobo ishisa kunehlobo.Idatha ibonisa ukuthi izinga lokushisa elijwayelekile ngoDisemba 2023, ngesikhathi sentwasahlobo yaseNingizimu Melika, lifudumele kunezinga lokushisa elijwayelekile ngoJanuwari noFebruwari 2024, phakathi nehlobo laseNingizimu Melika.
Ngokusho kochwepheshe besimo sezulu baseBrazil, amandla ka-El Nino azokwehla kancane kancane kusukela ekwindla sekwephuzile kuze kube sekuqaleni kobusika kulo nyaka, okungukuthi, phakathi kukaMeyi noJulayi 2024. Kodwa ngokushesha ngemva kwalokho, ukuvela kukaLa Nina kuzoba umcimbi omkhulu ongenzeka.Izimo ze-La Nina kulindeleke ukuthi ziqale engxenyeni yesibili yonyaka, amazinga okushisa angaphezulu kwamanzi ashisayo enkabeni nasempumalanga yePacific ehle kakhulu ngaphansi kwesilinganiso.
