Kodi La Nina ndi chiyani?
La Nina, lomwe limatanthawuza "Mtsikana Wamng'ono" m'Chisipanishi, amadziwikanso ndi mayina ena monga El Viejo kapena anti-El Nino, kapena kungoti "chochitika chozizira."
Mosiyana ndi El Nino, La Nina amachita mosiyana polimbitsa mphepo zamalonda ndikukankhira madzi ofunda ku Asia, pamene nthawi yomweyo akuwonjezera kukwera kuchokera ku gombe lakumadzulo kwa America kubweretsa madzi ozizira, odzaza ndi michere pafupi ndi pamwamba.
La Nina imachitika pamene madzi ozizira a Pacific amasunthira kumpoto, kusuntha mtsinje wa jet. Zotsatira zake, madera akumwera kwa United States amakhala ndi chilala pomwe Pacific Northwest ndi Canada kumagwa mvula yambiri komanso kusefukira kwamadzi.
Kutentha kwa dzinja kumadera akummwera kumakhala kotentha kuposa masiku onse pamene madera a kumpoto amakhala ndi nyengo yozizira kwambiri; kuonjezera apo, La Nina akhoza kuthandizira nyengo yamkuntho yamkuntho ndi madzi ozizira a Pacific ndi kuchuluka kwa zakudya.
Izi zitha kupanga malo abwino a zamoyo zam'madzi, kukopa mitundu yamadzi ozizira monga sikwidi ndi salimoni kugombe la California.

Kodi Zotsatira za La Nina ndi Chiyani?
Zotsatira za La Nina zikuphatikizapo:
- Ku Southeast Africa kumakhala kozizira komanso konyowa, komanso kumagwa mvula ku Eastern Australia.
- Kusefukira kwamadzi ku Australia.
- Kumpoto chakumadzulo kwa United States ndi kumadzulo kwa Canada kumazizira kwambiri.
- Mvula yamphamvu kwambiri ku India.
- Ma monsoons owopsa ku Southeast Asia ndi India.
- Chilala chachisanu ku Southern United States.
- Kutentha kokwera ku Western Pacific, Indian Ocean, ndi kugombe la Somalia.
- Mikhalidwe ngati chilala ku Peru ndi Ecuador.
Nchiyani Chimachititsa La Nina Kuchitika?
Pali zinthu zitatu zazikulu zomwe zimapangitsa kuti La Nina akhale ndi nyengo.
#1. Kutentha kwapanyanja kutsika
Pamene kutentha kwa nyanja kum'mawa ndi pakati pa Pacific Ocean kutsika pansi pa nyengo ya La Nina, kudzatsika 3-5 digiri Celsius pansi pa nthawi zonse.
M'nyengo yachisanu ya La Nina, Pacific kumpoto chakumadzulo kumakhala konyowa kuposa nthawi zonse, ndipo kumpoto chakum'maŵa kumakhala nyengo yozizira kwambiri, pamene Kumwera kwa Dziko lapansi kumakhala kozizira komanso kouma, zomwe zingayambitse kuopsa kwa moto ndi chilala kumwera chakum'mawa.
#2. Mphepo zamphamvu kwambiri zakum'mawa zamalonda
Mphepo zakum'mawa zikayamba kukhala zamphamvu, zimakankhira madzi ofunda kumadzulo, zomwe zimalola madzi ozizira kukwera kuchokera pansi pamtunda pafupi ndi gombe la South America. Chodabwitsa ichi chimapangitsa kuti La Nina ayambe, chifukwa madzi ozizira amalowa m'malo mwa madzi ofunda.
Mosiyana ndi zimenezi, El Niño amachitika pamene mphepo za kum’maŵa zamalonda zafowoka kapena kuwomba kumene, kuchititsa kuti madzi ofunda aunjikane kum’maŵa kwa Pacific ndi kusintha kwa nyengo.
#3. Njira yowonjezera
Pazochitika za La Nina, mphepo yamkuntho yakum'mawa ndi mafunde a m'nyanja zimakhala zamphamvu kwambiri ndipo zimasunthira chakum'mawa, zomwe zimapangitsa kuti pakhale njira yotchedwa upwelling.
Kukwera kumabweretsa madzi ozizira pamwamba, kuchititsa kuchepa kwakukulu kwa kutentha kwa nyanja.
Kodi Kusiyana Pakati pa La Nina ndi El Nino ndi Chiyani?
Asayansi sakutsimikizirabe za chiyambi chenichenicho chomwe chinayambitsa El Nino ndi La Nina, koma kusintha kwa mpweya pa Pacific equatorial Pacific kumachitika mwa apo ndi apo ndipo kumakhudza mphepo yamalonda kuchokera kummawa kupita kumadzulo.
La Nina imapangitsa madzi ozizira ochokera m'madera akuya kum'maŵa kwa Pacific kuti akwere, m'malo mwa madzi otenthedwa ndi dzuwa; Mosiyana ndi zimenezi, nthawi ya El Nino, mphepo zamalonda zimafooketsa madzi ofunda pang'ono amasunthira chakumadzulo zomwe zimapangitsa kutentha kwa madzi apakati ndi kum'mawa kwa Pacific.
Mpweya wofunda, wonyezimira umatuluka pamwamba pa nyanja ndikupangitsa mvula yamkuntho kudzera mumayendedwe, matupi akulu amadzi am'nyanja otentha amatulutsa kutentha kochuluka mumlengalenga, komwe kumakhudza kayendedwe kakuyenda kum'mawa-kumadzulo ndi kumpoto ndi kumwera.
Convection imagwira ntchito yofunika kwambiri pakusiyanitsa El Nino ndi La Nina; Panthawi ya El Nino, imapezeka makamaka kum'maŵa kwa Pacific, kumene madzi ofunda amapitirirabe, pamene pansi pa mikhalidwe ya La Nina amakankhidwira kumadzulo ndi madzi ozizira m'deralo.
Kodi La Nina Imachitika Kangati?
La Nina ndi El Nino nthawi zambiri amapezeka zaka 2-7 zilizonse, ndipo El Nino imachitika pafupipafupi kuposa La Nina.
Nthawi zambiri amakhala kwa gawo lalikulu la chaka.
La Nina amathanso kukumana ndi "double dip" chodabwitsa, pomwe chimayamba, chimayima kwakanthawi pamene kutentha kwa nyanja kumafika pamlingo wa ENSO-neutral, kenako kumayambanso kutentha kwamadzi kutsika.

Mafunso Ofunsidwa Kawirikawiri
Kodi La Niña ndi chiyani m'mawu osavuta?
La Nina ndi kachitidwe ka nyengo kudera lotentha la Pacific Ocean komwe kumadziwika ndi kutentha kozizira kwambiri kuposa kozizira kwambiri kumadera ake akum'mawa ndi pakati pa Pacific, zomwe nthawi zambiri zimatsogolera kusintha kwanyengo padziko lonse lapansi, kuphatikiza mvula yambiri kapena chilala m'malo ena.
La Nina imasiyana ndi El Nino yomwe imakhudza kutentha kwambiri kuposa kutentha kwapanyanja m'dera lomweli.
Kodi chimachitika ndi chiyani pa La Niña?
Zaka za La Nina zimakonda kutulutsa kutentha kwakukulu kwachisanu ku Southern Hemisphere ndi kumunsi kwa Kumpoto. Kuphatikiza apo, La Nina atha kuthandizira nyengo yamkuntho yamkuntho.
Kodi El Niño kapena La Niña yotentha ndi iti?
El Nino akunena za kutentha kwa nyanja ya Equatorial Pacific pamene La Nina akunena za kutentha kwa nyanja kwachilendo m'dera lomweli.
