Chii chinonzi La Nina?
La Nina, iro rinoshandura kuti "Musikana Mudiki" muchiSpanish, rinozivikanwawo nemamwe mazita akadai saEl Viejo kana anti-El Nino, kana kungoti "chiitiko chinotonhora."
Kusiyana neEl Nino, La Nina anoita zvinopesana nekusimbisa mhepo dzekutengeserana mberi uye kusunda mvura inodziya yakananga kuAsia, panguva imwe chete ichiwedzera kukwira kubva kumahombekombe ekumadokero kweAmericas ichiunza mvura inotonhora, ine kudya kunovaka padyo nepamusoro.
La Nina inoitika apo mvura inotonhora yePacific inotamira kuchamhembe, ichishandura rwizi rwejet. Nekuda kweizvozvo, nzvimbo dzekumaodzanyemba kweUnited States dzinosangana nekusanaya kwemvura nepo Pacific Northwest neCanada ichinaya zvakanyanya uye mafashama.
Kupisa kwechando munzvimbo dzekumaodzanyemba kunowanzodziya kupfuura nguva dzose nepo kuchamhembe kuine chando chinotonhorera; nekuwedzera, La Nina inogona kubatsira kune inoshingaira dutu mwaka uye inotonhora yePacific mvura ine yakawedzera huwandu hwezvinovaka muviri.
Izvi zvinogona kugadzira nharaunda yakanaka yezvipenyu zvemugungwa, zvichikwezva mhando dzemvura inotonhora senge squid nesalmon kuCalifornia pamhenderekedzo.

Ndeipi Migumisiro yaLa Nina?
Migumisiro yeLa Nina inosanganisira:
- Kunotonhora nekunyorova kwechando muSoutheast Africa, uye kuwedzera kwemvura muEastern Australia.
- Mafashamo akakosha muAustralia.
- Kunotonhora zvakanyanya kuchamhembe kwakadziva kumadokero kweUnited States uye kumadokero kweCanada.
- Kunaya kwemvura zhinji muIndia.
- Monsoons dzakaoma muSoutheast Asia neIndia.
- Kusanaya kwemvura munguva yechando kuMaodzanyemba kweUnited States.
- Kuwedzera tembiricha muWestern Pacific, Indian Ocean, uye kubva kumahombekombe eSomalia.
- Kusanaya kwemvura muPeru neEcuador.
Chii Chinoita Kuti La Nina Iitike?
Pane zvinhu zvitatu zvakakosha zvinopa maitiro emamiriro ekunze eLa Nina.
#1. Kudziya kwegungwa kwakadzikira
Sezvo tembiricha yepasi pegungwa kumabvazuva nepakati pePacific Ocean ichidzika panguva yeLa Nina, inodonha 3-5 madhigirii celsius pasi peyakajairwa.
Munguva yechando cheLa Nina, Pacific Northwest inowanzova yakanyorova kupfuura nguva dzose, uye Northeast inosangana nemamiriro okunze anotonhora zvikuru, nepo Southern Hemisphere inowanzosangana nemamiriro ezvinhu akaoma uye akaoma, izvo zvinogona kukonzera kuwedzera kwengozi yemoto uye kusanaya kwemvura kumaodzanyemba kwakadziva kumabvazuva.
#2. More simba easterly trade winds
Kana mhepo dzekutengeserana dzekumabvazuva dzinenge dzasimba, dzinosunda mvura inodziya yakawanda kumadokero, zvichibvumira mvura inotonhora kuti ikwire kubva pasi pepamusoro pegungwa pedyo nemhenderekedzo yeSouth America. Ichi chiitiko chinobatsira kuitika kwaLa Nina, sezvo mvura inotonhora inotsiva mvura inodziya.
Ukuwo, El Niño inoitika apo mhepo dzokutengesera dzokumabvazuva dzinopera simba kana kuti kutovhuvhuta kune rimwe divi, zvichiita kuti mvura inodziya iungane kumabvazuva kwePacific uye kuchinja kwemamiriro okunze.
#3. Iyo upwelling process
Munguva yezviitiko zveLa Nina, mhepo dzekutengeserana dzekumabvazuva uye mafungu emugungwa anosimba zvisina mwero uye anoenda kumabvazuva, zvichikonzera chiitiko chinonzi upwelling.
Kukwirisa kunounza mvura inotonhora pamusoro, zvichikonzera kudzikira kwakanyanya kwekushisa kwepasi pegungwa.
Ndeupi Musiyano Uripo Pakati PaLa Nina naEl Nino?
Masayendisiti anoramba asina chokwadi nezvechinokonzera icho chinotanga El Nino neLa Nina, asi mhepo inochinja pamusoro peequatorial Pacific inoitika zvishoma nezvishoma uye inokanganisa mhepo yekutengeserana kubva kumabvazuva kusvika kumadokero.
La Nina inokonzera kuti mvura inotonhora inobva munzvimbo dzakadzika dziri kumabvazuva kwePacific ikwire, ichitsiva mvura dzepamusoro dzinodziya nezuva; Ukuwo, panguva yeEl Nino, mhepo dzekutengeserana dzinopera simba zvekuti mvura shoma inodziya inofamba ichienda kumadokero zvichikonzera kudziya kwepakati nekumabvazuva kwePacific mvura.
Semhepo inodziya, ine mwando inosimuka kubva pamusoro pegungwa uye inogadzira mabhanan'ana kuburikidza ne convection, mitumbi mikuru yemvura inodziya yegungwa inoburitsa huwandu hwekupisa mumhepo, izvo zvinokanganisa mafambiro ekutenderera kumabvazuva-kumadokero uye kuchamhembe-kumaodzanyemba.
Convection inobata basa rinokosha mukusiyanisa El Nino kubva kuLa Nina; panguva yeEl Nino, inowanzoitika kumabvazuva kwePacific, uko mvura inodziya inopfuurira, nepo pasi pemamiriro eLa Nina yakasundidzirwa kumadokero nemvura inotonhorera munharaunda iyoyo.
Kakawanda Sei La Nina Inoitika?
La Nina naEl Nino zvinowanzoitika makore ese 2-7, neEl Nino ichiitika zvishoma kakawanda kupfuura La Nina.
Dzinowanzogara kwechikamu chikuru chegore.
La Nina inogona zvakare kusangana ne "double dip" chiitiko, kwainotanga kuitika, inomira kwenguva pfupi kana tembiricha yepasi pegungwa inosvika ENSO-neutral mazinga, uye yozovandudza zvakare kana tembiricha yemvura yadonha.

Chii chinonzi La Niña mumashoko akareruka?
La Nina inzira yemamiriro ekunze munzvimbo dzinopisa dzePacific Ocean inoratidzwa nekutonhora-kupfuura-kujaira kudziya kwepasi pegungwa munzvimbo dzayo dzekumabvazuva nepakati pePacific, kazhinji zvichikonzera shanduko yemamiriro ekunze epasi rose, kusanganisira kunaya kwemvura zhinji kana kusanaya kwemvura mune dzimwe nzvimbo.
