La Nina ngo-2020! Umthelela usuqalile. Ingabe lobu busika "bubanda ikakhulukazi"?

Qinisekisa! I-La Nina phenomenon yakhiwe ngo-2020, kanti i-US Climate Prediction Centre ikhiphe isitatimende esigunyaziwe, okusho ukuthi ukushintsha kwesimo sezulu emhlabeni wonke kungase kuqiniswe nakakhulu. Vele, ukwakheka kwe-La Nina phenomenon kuzoba nomthelela othile eChina. Okuhlukile, ngakho kufanele uzilungiselele. Lokhu kuphinde kube yinto entsha yemvelo ngemuva kwe-El Nino ebuthakathaka ngo-2020. Ukwakheka kweLa Nina kuzoletha isignali yokupholisa, okuyinto evamile.

Vele, nakuba ukwenzeka kukaLa Nina kunomphumela wokupholisa, akusho ukuthi umhlaba uzoba nesimo sokupholisa esikhulu “esinzima”, ngoba ukufudumala kwembulunga yonke kwanamuhla kungase kube kukhulu kakhulu kunedigri yokupholisa iLa Nina, ngakho-ke u-2020 usengaba. unyaka oshisa kakhulu emlandweni.

I-NOAA iqinisekise ubukhona be-LaNi ó a

Ngokusho kwedatha entsha yomphakathi ekhishwe yi-NOAA ngoSepthemba, isenzakalo sikaLa Nina senzeka ngempela ngo-Agasti, okulindeleke ukuthi siqhubeke ubusika bonke ngamathuba angu-75%, ngakho-ke lobu busika buyoba yinye yezikhathi eziyinhloko ngo-September. I-La Nina phenomenon. Ngokusho kwedatha yokuqapha ye-Ni ﹣ o3.4 ye-anomalies yokushisa kwamanzi olwandle ezinyangeni zamuva, sebefinyelele inani eliphakathi, futhi inani eliphansi lomkhawulo elingu-0.6 ° C livele kudatha eqoqwe ngo-August, nakuba lokhu kungekuphela ejwayelekile. Kodwa-ke, idatha ebanzi ifinyelele inani elimaphakathi lesikhathi eside ukusuka ku-1986 kuya ku-2015.

Ngesikhathi esifanayo, ngokusho kwamamodeli amaningi wekhompiyutha ashukumisayo, izinga lokushisa lolwandle lizohlala lingaphansi - 0.5 ° C umkhawulo weLa Nina ubusika bonke. Njengomphumela, i-NOAA ikhipha amathuba angama-75% ebusika. Ngaphansi kwethonya le-La Nina phenomenon, ukuguqulwa kokujikeleza komkhathi wase-Pacific kuzoqhubeka nokuthinta isimo sezulu somhlaba kanye nezimo zesimo sezulu. Yize i-El Nino nayo ingaba nomthelela, bobabili baphambene. Yebo. Ngesikhathi esifanayo, isenzakalo sikaLa Nina singase futhi sibangele imvula engaphezu kwesilinganiso e-Indonesia, isimo sezulu esipholile nesinomswakama eningizimu ye-Afrika, isimo sezulu esomile eNingizimu-mpumalanga ye-China kanye neminye imithelela.

Uye waba yini umthelela kaLa Nina?

Manje into engathi sína kakhulu i-United States, ngakho ithonya layo seliqalile. Ngokolwazi olukhishwe yi-U.S. Meteorological Center, umlilo okhona e-United States ungase uqhubeke kuze kube uNovemba noma ngisho noDisemba ngemva kokubunjwa kweLa Nina. Ngesikhathi esifanayo, uRyan truchelut, uMongameli we-weather tiger LLC, naye wathi lokhu kwandisa izinga lokushisa eliphezulu elikhona kanye nezinkinga zesomiso. Ngenxa yalokho, izinga lokushisa eliphezulu, isomiso, imililo yequbula nezinye izinkinga e-United States namuhla "kuyimikhiqizo" ye-La Nina phenomenon. Umlilo waseCalifornia e-United States usuphenduke inkathi yomlilo wequbula embi kakhulu emlandweni. Ngokokuqala ngqa, umhlaba ongamahektha ayizigidi ezingu-2.5 ushiswe umlilo.

Ngesikhathi esifanayo, izivunguvungu ziyaqhubeka olwandle, icala leSiphepho uDavid Lara. Ngesikhathi esifanayo, izimo ezilandelayo zingase futhi ziholele ebusika obubandayo enyakatho ye-United States, okuholela ezikhukhuleni enyakatho ye-Australia kanye nokukhuphuka kwemvula e-Indonesia naseBrazil ezifundazweni ezintathu eziseningizimu. Kunjalo, idatha yakamuva evela ku-NASA ikhombisa ukuthi ekuqaleni kukaSepthemba 2020, amazinga okushisa eningizimu-ntshonalanga ye-United States empeleni ayeqashwe emazingeni okushisa ama-degree angama-45. Lokhu kuyethusa kakhulu, ngoba i-United States ayikaze ibe namazinga okushisa aphezulu njengamanje, futhi ivele ngo-2020.

Ngakho-ke, kungashiwo ngokucacile ukuthi i-La Nina phenomenon yakhiwe futhi ithonya layo e-United States selivele selivele. Yebo, lokhu kusho ukuthi umthelela ezweni lethu uzoqhubeka nokukhula. Kudingeka sinake izinguquko zesimo sezulu emhlabeni kanye nakuyo yonke iNorthwest Pacific. Lolu hlobo lwesimo, i-typhoon embryo yanamuhla ivela ngokungapheli, ingase ihlobane nalokhu. Yebo, silapha ukuze sigxile emthelela ongase ube khona kulobu busika.

Ngo-2020, isimo sezulu kungenzeka sishintshe kakhulu. Imuphi umthelela into kaLa Nina ezoba nayo eChina?

Uma nje sikhuluma ngoLa Nina, wonke umuntu angacabanga ngokuqondile ngesimo sezulu seqhwa neqhwa ngo-2008. Kungashiwo ukuthi indawo enkulu yezwe lethu yayineqhwa eliningi ngo-2008, futhi i-La Ni La phenomenon yamanje isekelwe. kunkomba. Bheka, ibuthakathaka, kodwa amathuba azoqhubeka anda. Phela, izinga lokushisa ngo-Agasti lalingu-0.6 ° C. Uma sibheka i-Ni yakamuva yanamuhla? O3.4 amanani, iyaqhubeka. Ngemuva kokuncipha, isondele ngqo ku-0.8 ° C, ngakho-ke ukuqina kwe-La Nina phenomenon kungakhula.

Yiqiniso, lokhu kusho ukuthi ithonya le-La Nina phenomenon lingakhuphuka. Ngokwesimo esijwayelekile "sonyaka weLa Nina", kulula ukwenza isimo sezulu sasebusika sezwe lethu sibe sibanda, futhi kulula ubusika obubandayo. Ngakho-ke, kudingeka silungiselele kusengaphambili, kodwa ngokombono wokufudumala kwembulunga yonke, ithuba lokubuyisela emuva ubusika obufudumele lisencane kakhulu, okusho ukuthi, kungenzeka ukuthi ubusika obufudumele bube bukhulu, ngakho wonke umuntu kufanele ahlale enaka. ukuthuthukiswa kwe-La Nina phenomenon. Isaqhubeka nokuwa, okulingana nesignali ethuthukisiwe.

I-World Meteorological Organization iphinde yathi noma kwenzeka lesi sigameko sikaLa Nina, mancane amathuba okuthi siguqule ukufudumala kwembulunga yonke, ngakho lo nyaka ungase ube unyaka oshisa kakhulu emlandweni. Yebo, kungase kushisa kakhulu ezweni lakithi, ngakho sishilo ukuthi ubusika obufudumele buvame kakhulu. Lokhu kungenxa yokuguquguquka kwesimo sezulu.

Ngenxa yezici ezihlukahlukene zesimo sezulu, akunakwenzeka ukunquma ukuthi kuzoba nobusika obubandayo noma ubusika obufudumele. Kuze kube manje, kungashiwo ukuthi alikho izwe emhlabeni elingasho ngokunembile ukuthi izwe liyabanda noma lifudumele. Ungangizwa kabi. Kusukela kumkhuba walo nyaka, kungenzeka ukuthi ubusika obufudumele buyoba bukhulu, futhi ngeke kube khona isimo sezulu esibanda kakhulu. Kuqondiswe kwireferensi.
