Ezinsukwini ezimbalwa ezedlule, iNingizimu Melika ibe yinkundla ye- igagasi elibandayo le-polar elingakaze libonwe ngaphambili okuyinto eshiya uphawu e-Argentina, eChile nase-Uruguay. Ukufika kungazelelwe kwalesi sixuku somoya oneqhwa, ovela e-Antarctica, kuye kwabangela amazinga okushisa aphansi ngokungavamile, ngeziningi amarekhodi omlando kokubili emadolobheni nasezindaweni zasemakhaya, futhi kubangele uchungechunge lwezinyathelo ezingavamile zeziphathimandla ukubhekana nemiphumela.
Lesi simo sezulu esibi kakhulu sekubangele ukufa okungenani kwabangu-15, ikakhulukazi phakathi kwabantu abangenamakhaya abachayeka ezimweni ezimbi. I-Buenos Aires yabhekana nosuku lwayo olubanda kunawo wonke kusukela ngo-1991, iqopha -1.9 ° C, kuyilapho amanye amadolobha, njengedolobha elisogwini i-Miramar, ebona iqhwa okokuqala ngqa emashumini amathathu eminyaka. Eningizimu ye-Argentina, uMaquinchao wafinyelela -18 ° C, futhi iPatagonia yaze yafinyelela -20 ° C kwezinye izindawo.
Izinyathelo ezisemthethweni nokuphazamiseka kwesevisi
Umthelela wegagasi elibandayo uphoqe ohulumeni besifunda ukuthi ukubeka phambili ukuhlinzekwa kwegesi ezindlini, ukumisa ukunikezwa ezimbonini naseziteshini zesevisi. Lesi sinqumo senziwe Kulandela ukwanda okungakaze kubonwe kwesidingo segesi yemvelo, okubangele ukunqamuka kukagesi emadolobheni anjengeMar del Plata neBuenos Aires, lapho izinkulungwane zabantu zahlala amahora amaningi zingenakushisa nogesi.
Izikole, izakhiwo zomphakathi namabhizinisi nazo zathinteka, zasala zivaliwe ezindaweni eziningana njengesinyathelo sokugcina amandla. I-Mar del Plata, eqhele ngamakhilomitha angu-380 ukusuka e-Buenos Aires, ihlangabezane nobunye ubusika obunzima kakhulu kwinkumbulo yakamuva, namasistimu okushisa adilika ngenxa yokushoda kwezinto.
Isexwayiso esibomvu nesimo esiphuthumayo e-Uruguay naseChile
E-Uruguay, igagasi elibandayo liholele e isimemezelo "sesaziso esibomvu" sikazwelonke, okuvumela ukufuduka kwabantu abangenamakhaya ngenkani baye ezindaweni zokukhosela. Ukushona okuyisithupha okuqinisekisiwe kukhomba ukuba sengozini kwalabo abahlala emigwaqweni lapho bebhekene nalezi zimo ezimbi kakhulu. I-Montevideo ihlangabezane nenani eliphansi kakhulu kusukela ngo-1967, nge 5.8 ° C.
I-Chile, ngakolunye uhlangothi, irekhodiwe -9.3 °C e-Chillán kanye nezinyathelo zokukhosela ezikhethekile nezindlela zokusiza. Amadolobha aseSantiago, eRancagua, naseTalca nawo abhekana nokuwohloka okukhulu kwezinga lomoya ngenxa yokunganyakazi komoya obandayo nokunqwabelana kwezinto ezingcolisayo.
Ukuwa kweqhwa okumangalisayo nokulimala kwezomnotho
Esinye sezici ezigqama kakhulu zaleli wave polar kube yi- ukubonakala kweqhwa ogwadule lwase-Atacama, indawo eyome kakhulu emhlabeni, into engakaze ibonwe eminyakeni engaphezu kweshumi. Ngokunjalo, I-Mar del Plata nezinye izindawo ezingavamile ogwini lwase-Argentina wavuka embozwe ezimhlophe, okuphazamisa isimiso sansuku zonke sezakhamuzi zakhona.
I-Las imiphumela yezomnotho nezenhlalo Akuphelanga sikhathi esingakanani bafika. Abalimi enkabeni yeChile nasenyakatho yePatagonia babikile Ukulahlekelwa okukhulu ezitshalweni zezithelo nasezitshalweni zasebusika, ngenxa yesithwathwa. Ezokuthutha nemisebenzi yesikole ibe neziphazamiso eziningi, ikakhulukazi ezifundeni ezingasijwayele isimo sezulu esibi kangaka sasebusika.
Isimo sezulu kanye nencazelo yesayensi
Ngokusho kwe- Inhlangano Yezwe Yezulu (WMO), igagasi elibandayo laqala ngoJuni 26 futhi lafinyelela umvuthwandaba walo ekupheleni kwenyanga, lapho i-Argentina neChile zaziphakathi kwezindawo ezibanda kakhulu emhlabeni ngaphandle kwezigxobo. Umsuka walo mkhuba Kuthiwa ku-a i-polar anticyclone eye yahambisa umoya ovela eningizimu, igcina isibhakabhaka esicwebile nesithwathwa eside ngisho nasezindaweni eziphansi, kude nokujwayelekile.
Ongoti besimo sezulu, njengochwepheshe besimo sezulu uRaúl Cordero kanye nabakhulumeli beNational Meteorological Service yase-Argentina, baveza ukuthi ukushintshashintsha kwesimo sezulu kanye nokuba buthaka kwe-polar jet stream Zenza kube lula ukufika kwalezi zindimbane zomoya oneqhwa ezindaweni ezingalindelekile. Nakuba amagagasi abandayo evame ukungavamile kunamagagasi okushisa, iziqephu ezidlulele zamazinga okushisa aphansi zingaba namandla kakhulu futhi zibhebhethekiswe ukushintsha kwesimo sezulu.
Ku-panorama yomhlaba wonke, umehluko phakathi kwe- amagagasi okushisa enyakatho nenkabazwe Futhi lesi siqephu esibucayi eNingizimu Melika sibonisa ubunkimbinkimbi kanye nemiphumela eyeqisayo yesimo sezulu samanje, esibonisa ukuthambekela ekwandiseni zonke izimo zezulu.
Ukulandelana okusheshayo kwezinsuku eziqandisiwe, amazinga okushisa arekhodiwe kanye nokusabela kweziphathimandla kugqamisa ubukhulu benselele yesimo sezulu isifunda sibhekene. Ikhono lezinsizakalo zokuzivumelanisa nezimo nokuvikela abasengozini kakhulu lizobaluleka, njengoba izibikezelo zibikezela ukuthi lo mkhuba wokweqisa ungase uphindwe noma uqiniswe ebusika obuzayo.
