Yintoni uLa Nina?
I-La Nina, eguqulela "Intombazana encinci" ngesiSpanish, iyaziwa ngokuqhelekileyo ngamanye amagama afana ne-El Viejo okanye i-anti-El Nino, okanye nje "njengesiganeko esibandayo."
Ngokuchaseneyo ne-El Nino, uLa Nina wenza ngokuchaseneyo ngokomeleza imimoya yorhwebo ngakumbi kwaye etyhala amanzi ashushu ukuya e-Asiya, ngelixa kwangaxeshanye eqinisa ukunyuka kunxweme olusentshona lwaseMelika ezisa amanzi abandayo, atyebileyo ngezondlo kufutshane nomphezulu.
ILa Nina yenzeka xa amanzi abandayo ePasifiki etshintshela emantla, etshintsha umsinga wejethi. Ngenxa yoko, imimandla esemazantsi e-United States ifumana imbalela ngelixa iPacific Northwest kunye neKhanada ifumana imvula enkulu kunye nezikhukhula.
Amaqondo obushushu asebusika kwimimandla esemazantsi athanda ukuba shushu kunesiqhelo ngelixa imimandla esemantla ifumana ubusika obupholileyo; ukongeza, uLa Nina unokufaka isandla kwixesha lenkanyamba esebenzayo kunye namanzi abandayo ePasifiki kunye nezixa ezandisiweyo zezondlo.
Oku kunokudala imeko efanelekileyo kubomi baselwandle, kutsala iintlobo zamanzi abandayo ezifana neskwidi kunye nesalmon kunxweme lwaseCalifornia.

Imibuzo esebenzayo yenza abafundi bakho bacengceleze amagama anzima ejografi-alunaxinzelelo ngokupheleleyo
Ziziphi iimpembelelo zikaLa Nina?
Iziphumo zikaLa Nina ziquka:
- Ubusika obubandayo nobumanzi kuMzantsi-mpuma Afrika, kunye nokwanda kwemvula eMpuma Ostreliya.
- Izikhukula ezibalulekileyo eOstreliya.
- Ubusika bubanda kakhulu kumntla-ntshona weUnited States nakwintshona yeKhanada.
- Iimvula ezinkulu zemonsoon eIndiya.
- Iimonsoons ezinzima eMzantsi-mpuma Asia naseIndiya.
- Imbalela yasebusika kuMazantsi eUnited States.
- Amaqondo obushushu aphakamileyo kwiNtshona yePasifiki, kuLwandlekazi lwaseIndiya, nakunxweme lwaseSomalia.
- Iimeko ezifana nembalela ePeru nase-Ecuador.
Yintoni ebangela ukuba kwenzeke uLa Nina?
Kukho izinto ezintathu eziphambili ezinegalelo kwindlela yemozulu yaseLa Nina.
#1. Umphezulu wolwandle amaqondo obushushu athotyiweyo
Njengoko amaqondo obushushu omphezulu wolwandle enqumla empuma nakumbindi woLwandlekazi lwePasifiki ehla ngexesha leLa Nina, aya kuhla nge-3-5 degrees celcius ngaphantsi kwesiqhelo.
Ngexesha laseLa Nina ebusika, iPacific Northwest idla ngokuba manzi kunesiqhelo, kwaye iNyakatho-mpuma ifumana imozulu ebanda kakhulu, ngelixa i-Southern Hemisphere ifumana iimeko ezinzima kunye nezomileyo, ezinokukhokelela ekunyuseni komlilo kunye nesomiso eMzantsi-mpuma.
#2. Imimoya yorhwebo yasempuma enamandla ngakumbi
Xa imimoya yorhwebo yasempuma isiba namandla, ityhala amanzi ashushu ngakumbi ukuya ngasentshona, ivumela amanzi abandayo ukuba anyuke ukusuka ngaphantsi komhlaba kufuphi nonxweme lwaseMzantsi Merika. Le nto inegalelo ekuveleni kukaLa Nina, njengoko amanzi abandayo ethatha indawo yamanzi afudumeleyo.
Kwelinye icala, iEl Niño ibakho xa imimoya yorhwebo yasempumalanga isiba buthathaka okanye ide ivuthuze isiya kwelinye icala, ibangela ukuba amanzi ashushu aqokelelane kwimpuma yePasifiki nokuguquguquka kwemozulu.
#3. Inkqubo yokunyusa
Ngexesha lemisitho yeLa Nina, imimoya yorhwebo yasempuma kunye nemisinga yolwandle iba namandla ngokungaqhelekanga kwaye ibheka ngasempuma, ikhokelela kwinkqubo ebizwa ngokuba kukunyuka.
Ukunyuka kuzisa amanzi abandayo phezu komhlaba, nto leyo ebangela ukwehla okubonakalayo kubushushu bolwandle.
Uthini Umahluko phakathi kukaLa Nina no-El Nino?
Iingcali zenzululwazi zihlala zingaqinisekanga ngeyona nto ibangela u-El Nino kunye noLa Nina, kodwa utshintsho loxinzelelo lomoya kwi-equatorial Pacific lwenzeka ngokukhawuleza kwaye luchaphazela imimoya yorhwebo ukusuka empuma ukuya entshona.
ILa Nina ibangela ukuba amanzi abandayo asuka kwimimandla enzulu kwimpuma yePasifiki anyuke, ethabathel’ indawo amanzi angaphezulu afudunyezwe lilanga; ngokuchaseneyo, ngexesha El Nino, imimoya yorhwebo buthathaka ngoko ngaphantsi amanzi afudumeleyo ihambisa ngasentshona kubangele ukufudumala kumbindi nasempuma Pacific amanzi.
Njengoko umoya ofudumeleyo, nofumileyo unyuka usuka kumphezulu wolwandle kwaye uvelise iindudumo ngokuntywila, imizimba emikhulu yamanzi olwandle afudumeleyo ikhupha ubushushu kwiatmosfera, nto leyo echaphazela iipatheni zokujikeleza empuma-ntshona nakumantla-mazantsi.
I-Convection idlala indima ephambili ekuhlukaniseni u-El Nino kuLa Nina; ngexesha le-El Nino, lenzeka kakhulu kwimpuma yePasifiki, apho amanzi afudumeleyo eqhubeka khona, ngelixa phantsi kweemeko zeLa Nina iye yatyhalelwa ngakumbi ngasentshona ngamanzi apholileyo kuloo mmandla.
Iyenzeka kangaphi iLa Nina?
ILa Nina kunye no-El Nino ngokuqhelekileyo zenzeka rhoqo emva kweminyaka emi-2-7, kunye ne-El Nino eyenzeka kancinane kunoLa Nina.
Ngokuqhelekileyo zihlala ixesha elide lonyaka.
I-La Nina inokufumana into "yokudipha kabini", apho iqala ukukhula, iyeke okwexeshana xa amaqondo obushushu olwandle efikelela kumanqanaba angathathi hlangothi e-ENSO, aze aphuhlise kwakhona xa amaqondo obushushu ehla.

Imibuzo ebuzwa qho
Yintoni iLa Niña ngamagama alula?
ILa Nina yipatheni yemozulu kuLwandlekazi lwePasifiki yetropikhi ephawulwa ngamaqondo obushushu angaphezulu kunesiqhelo olwandle kummandla wasempuma nombindi wePasifiki, edla ngokukhokelela kutshintsho kwiipatheni zemozulu yehlabathi, kuquka imvula eninzi okanye imbalela kwiindawo ezithile.
ILa Nina ime ngokungafaniyo ne-El Nino ebandakanya ubushushu obungaphezu kwesiqhelo bomphezulu wolwandle kulo mmandla.
Kwenzeka ntoni ebudeni beLa Niña?
Iminyaka yeLa Nina idla ngokuvelisa amaqondo obushushu aphezulu asebusika kwi-Hemisphere eseMazantsi nasezantsi kuMntla. Ukongeza, uLa Nina unokufaka isandla kwixesha lenkanyamba.
Yeyiphi i-El Niño efudumeleyo okanye iLa Niña?
I-El Nino ibhekisela kubushushu obungaqhelekanga bolwandle kwi-Equatorial Pacific ngelixa iLa Nina ibhekisela kumaqondo obushushu aphantsi ngokungaqhelekanga kulo mmandla.
