I-United States National Oceanic and Atmospheric Administration yenze ngokusemthethweni i ukubuya kweLa NiƱa, kunye neemeko esele zikhona kwiPasifiki yetropiki kunye neempawu ezihambelana nesiqendu ubuthathaka kunye nexesha elifutshaneInqaku eliphambili lesalathiso lijikeleze i--0,5 Ā° C kwindawo ye-NiƱo 3.4, indawo ephawulekayo echaza ukuqala kwesigaba esibandayo se-ENSO.
Emva kweeveki ezininzi kunye iimpawu ezidanyazayo ukupholisa, ipateni idityanisiwe kwaye kulindeleke ukuba iqhubeke ukusuka kuDisemba ukuya kuFebruwari, kunye namathuba angaphezu kwama-50%. Lo mzekelo ungaguqulelwa kwi utshintsho kwimvula kunye nobushushu eMzantsi Melika, ngokuqwalaselwa ngokukodwa kumazantsi eBrazil naseUruguay, kunye nokubeka iliso ngokusondeleyo eArgentina.
Kwenzeka ntoni kwi-equatorial Pacific
Iqondo lobushushu kumphezulu wolwandle olungaqhelekanga kummandla we-NiƱo 3.4 lijikelezile -0,5 Ā° C, ukubeka inkqubo kumda we-NiƱa ebuthakathaka. Ukupholisa kugxile kumbindi-mpuma wePasifiki, ngelixa i imimoya yorhwebo Amaza anamandla ngakumbi atyhala amanzi ashushu ngasentshona kwaye akhuthaza amanzi abandayo ukuba anyukele empuma. Oku kudityaniswa komeleza i Ukujikeleza kweWalker kwaye ilungisa iipateni zemvula kwisikali seplanethi.
Ubude bexesha elilindelekileyo kunye nokuvela kwesiqendu
Ezona mpembelelo zengingqi ezinokwenzeka
EBrazil, ukupholisa kwePasifiki kudla ngokuguqulela eRio Grande do Sul njenge indawo ebalulekileyo ngenxa yentsilelo emazantsi, ngelixa umntla nomntla-mpuma udla ngokubhalisa imvula ephezulu ukuya kumndilili. Ukongeza, ukuphindaphinda kwe ukungena komoya obandayo, kunye nokwenzeka kokuqhambuka okuphawulweyo ngakumbi ekupheleni konyaka wokuqala wesiqendu.
IUruguay yayiza kujongana nemeko imvula engaphantsi kwesiqhelo kwisiqingatha sokugqibela sonyaka, kunye neempembelelo ezinokuthi zibe kho kwi amasebe omda namazantsi eBrazil kunye nesidingo sokuhlengahlengisa ulawulo lwamanzi kwiinkqubo zasedolophini nasezilalini.
E-Argentina, i-panorama ibonakala ezahlukeneyo Ngokwee-arhente zelizwe: unxweme kunye nomntla-mpuma unokubona imvula engaphantsi kwesiqhelo; umntla-ntshona unokuba nemvula engaphezu komndilili; ummandla osembindini uya kusondela kumaxabiso aqhelekileyo, kunye ne Patagonia ingabonisa umkhethe phakathi kwesiqhelo nesisezantsi. I ukudibanisa ulwandle-moya, isitshixo sokugqiba ukuchaza umqondiso.
Iimpembelelo emaphandleni nakwi-ikhosistim
ILa NiƱa inokubeka uxinzelelo kwimveliso ingqolowa, iimbotyi zesoya kunye nombona ngenxa yokungabikho kwamanzi kwizigaba ezibalulekileyo, kunye nesivuno esincinci, uxinzelelo olungakumbi lokunkcenkceshela kunye ukuba sesichengeni okukhulu imali kubavelisi abaphakathi nabancinci.
El ukusilela kwamanzi kwandisa ingozi yokutsha kwehlathi ngokujika uhlaza olomileyo lube sisibaso, kunye iiqabaka zamva kungenza kube nzima ukukhula kweziqhamo kunye newayini kwiindawo ezinochuku kuqhambuko lwengqele.
I-ecosystems nayo iyachaphazeleka: ukuncitshiswa kokuhamba emilanjeni kunye imigxobhozo inciphisa iindawo zokuhlala, ibeka esichengeni intlobo-ntlobo zezinto eziphilayo kwaye ichaphazela ubonelelo ngamanzi kuluntu kunye nemisebenzi yezoqoqosho.
Zeziphi iimpawu ekufuneka uzibukele kwaye uzilungiselele njani
Kuyacetyiswa ukubeka iliso ngokusondeleyo ukuvela kwe Inkwenkwe 3.4, i imimoya yorhwebo kunye nokujikeleza kwe-Walker, ukongeza kwi-coupling yolwandle-atmosphere. Iinzuzo zokwenziwa kwezigqibo ukusuka uqikelelo lwamaxesha onyaka, izicwangciso zokunkcenkceshela eziguquguqukayo, i-inshorensi ye-climate-indexed, kunye nokulungelelaniswa kwamashishini karhulumente kulawulo lomngcipheko.
Ngesigaba esibandayo esele sivuliwe, yonke into ikhomba isiqendu ubunzulu obufutshane kunye obuphantsi kodwa neziphumo palpable in the Southern Cone: imvula encinane kumazantsi Brazil kunye Uruguay, kunye a ukuziphatha ngokungalingani E-Argentina, ukuqhubeka kokubeka iliso kunye nokuhlengahlengiswa kwesicwangciso kuya kuba sisitshixo kwimozulu yexesha lonyaka kunye nokuvezwa okuncinci okunokwenzeka.
