Chimachitika ndi chiyani ngati titha mayina amkuntho a Atlantic?

The 2020 Nyengo yamkuntho ya Atlantic yayamba ndikuyamba kukonza, ndi pa tempo yake yapano, mvula yamkuntho yotentha imatha kupitilira mindandanda ya 21 mayina omwe angagwiritsidwe ntchito kukhazikitsa mapulogalamu — chinthu chimodzi chomwe chachitika nthawi imodzi yokha m'mbiri yakale yolembedwa.

Kuyambira Lachinayi, Sept. 3, zakhalapo 15 adatcha mapulogalamu otentha m'mphepete mwa nyanja ya Atlantic ndi melancholy imodzi yomwe sinatchulidwe, bwino pamwamba pa zofala pa mlingo uwu mkati mwa nyengo. Nthawi zina, pali mophweka 12 anatchula mikuntho mu nyengo yonse.

Ndi mikuntho yambiri kale kuposa kutalika kwa nyengo yamkuntho ya Atlantic, yomwe ndi Sept. 10, akuyesera mochulukira zotheka kuti olosera atha kugwiritsa ntchito njira yodziwika kuti azitcha mapulogalamu otentha.

Mayina omwe angaperekedwe ku mphepo yamkuntho ndi mphepo yamkuntho mkati mwa nyanja ya Atlantic ndi adatsimikiza zaka zambiri pasadakhale ndi World Meteorological Organisation (Mtengo WMO).

“Kuyang'ana kwa kutchula ma namondwe (mvula yamkuntho) kuyambira zaka zapitazo ndi cholinga chothandizira kuzindikira kwakanthawi kwa mphepo yamkuntho mu mauthenga ochenjeza chifukwa mayina amaganiziridwa kuti ndi osavuta kukumbukira kuposa manambala ndi ziganizo zamakono.,” WMO yafotokozedwa.

Mndandanda wa mayina ndi wa zilembo, kuyambira ndi A nyengo iliyonse; komabe, sichimaphatikizapo mayina a onse 26 makalata. Olosera amalumpha zilembo Q, U, X, Y ndi Z chifukwa cha mayina ochepa okha omwe amayamba ndi zilembo izi.

Pambuyo pa chizindikiro chomaliza pamndandanda chikugwiritsidwa ntchito, njira yomwe mikunthoyo imatchulidwira kusinthidwa kwambiri.

Si zachilendo kuti pakhale wamkulu kuposa 21 anatchula mikuntho mu nyengo imodzi, komabe pali zolozera pazomwe zikuchitika.

“Panthawi yomwe mphepo yamkuntho yopitilira makumi awiri ndi imodzi imachitika m'nyanja ya Atlantic munyengo imodzi., mikuntho yowonjezera idzatenga mayina kuchokera ku zilembo zachi Greek,” National Hurricane Heart idatero.

Chifukwa cha izi, mkuntho wa makumi awiri ndi awiri womwe umatchedwa mkuntho ukhoza kutchedwa chilembo choyambirira mu zilembo zachi Greek, Alpha, kutengedwa ndi kalata yachiwiri, Beta, ndi zina zotero. Mu zonse, pali 24 zilembo za zilembo zachi Greek zomwe zingagwiritsidwe ntchito.

Popeza kutchula mikuntho ndi mphepo zamkuntho zinayamba pakati pa zaka za m'ma 1900, panali chaka chimodzi chokha pomwe pakhala pali zazikulu kuposa 21 otchedwa namondwe mu nyengo imodzi yamkuntho.

Wodziwika bwino 2005 Nyengo ya mphepo yamkuntho ya Atlantic inachititsa kuti pakhale mbiri 28 dzina lake namondwe. Mkuntho wambiri unakula kukhala mphepo zamkuntho zakale, pamodzi ndi Katrina, Rita ndi Wilma chaka chimenecho. “Nyengoyi inali nthawi yoyamba imene akatswiri a zanyengo anayamba kugwiritsa ntchito zilembo zachigiriki potchula mvula yamkuntho.,” WMO idatero.

Mu July, Akatswiri a zanyengo a AccuWeather analipo kulosera nyengo yamkuntho yamkuntho ya Atlantic mpaka 24 dzina lake namondwe, ndipo kuneneratu kumeneko kukuchitika kuti kuchitike.

Pa mlingo uwu, pali kuthekera kokulirapo kuti aliyense azindikire amagwiritsidwa ntchito nyengo yamkuntho pambuyo pake ena. Akatswiri a zanyengo a AccuWeather ali kale otanganidwa kuyang'anira madera omwe akuyembekezeka kuti atukuke kutali mkati mwa beseni.

Mayina asanu ndi limodzi okha ndi omwe atsala kuti agwiritsidwe ntchito kale kuposa momwe olosera amafunikira kuti alowe mu zilembo zachi Greek: Paulette, Rene, Sally, Teddy, Vicky ndi Wilfred.

Ngati zilembo zachi Greek ziyenera kugwiritsidwa ntchito 2020, idzagwirizana ndi ndandanda yofanana ndi 2005, kuyambira ndi Alpha. Zimenezi n’zofanana ndi mmene mayina ambiri amagwiritsidwiranso ntchito zaka zingapo zilizonse, mpaka chizindikirocho chinachotsedwa.

Komabe, pali kusiyana kumodzi kwakukulu pakati pa mayina okhazikika ndi zilembo zachi Greek: Zilembo za zilembo zachi Greek zomwe zitha kugwiritsidwa ntchito pamapulogalamu otentha sangathe kuchotsedwa.

“Ngati mkuntho waukulu wotchulidwa ndi chilembo cha zilembo zachi Greek, ku Atlantic kapena ku Japan North Pacific Basin, analingaliridwa kukhala oyenera ‘kupuma pantchito,’ idzaphatikizidwa m'ndandanda wa mayina omwe adapuma pantchito omwe ali ndi zaka zakuchuluka komanso zambiri, komabe chilembo cha munthu aliyense mkati mwa Zilembo za Chigiriki chikapitiriza kupezeka kuti chigwiritsidwe ntchito posachedwa,” WMO yafotokozedwa.

Ngakhale nyengo yamkuntho ya Atlantic imatha pa Nov. 30, pali chiyembekezo choti pulogalamu imodzi kapena ziwiri zakutentha zitha kuchitika kale 2020 imakhudzanso mwatsatanetsatane.

Pafupi ndi nsonga ya 2005, kutsatira mbiri yakale yamkuntho nyengo, Tropical Storm Zeta idawonekera kum'mawa kwa nyanja ya Atlantic pa Dec. 30. Zeta inakhala pamadzi otseguka a Nyanja ya Atlantic mpaka Jan. 7, 2006, kale kuposa momwe idasweka. Zeta anali mkuntho wachisanu ndi chimodzi kuti apatsidwe mbiri kuchokera ku zilembo zachi Greek kuti yr.

Pambuyo pa kalendala kutembenukira 2021, Malo otentha otsatirawa mkati mwa nyanja ya Atlantic akhoza kutchedwa Ana.
