Kwenzekani uma siphelelwa amagama esiphepho sase-Atlantic?

I 2020 Isikhathi sesiphepho sase-Atlantic icishiwe ekuqaleni kokusetha irekhodi, nangesikhathi sayo samanje, ukuthembela kwesiphepho sasezindaweni ezishisayo kungaba ngaphezu kohlu lwe 21 amagama angasetshenziswa ukusungula izinhlelo — into eyodwa eye yenzeka ngesikhathi esisodwa esihlukile esikhathini esidlule esirekhodiwe.

Kusukela ngoLwesine, Sept. 3, bekhona 15 ebizwa ngokuthi izinhlelo ezishisayo ngaphakathi kwe-Atlantic basin kanye ne-melancholy eyodwa eshisayo engashiwongo, ngaphezu kokujwayelekile kuleli zinga phakathi nesizini. Ngezinye izikhathi, kukhona kalula 12 okuthiwa izivunguvungu ngesizini yonke.

Ngeziphepho eziningi ngaphambi kokuphakama kwesiphepho sase-Atlantic, okunguSept. 10, izama ngokuqhubekayo ukuthi ababikezeli bangasebenzisa uhlelo oluhlukile ukubiza izinhlelo ezishisayo.

Amagama angase anikezwe iziphepho ezishisayo neziphepho ngaphakathi kolwandle lwase-Atlantic kunqunywe iminyaka kusengaphambili yi-World Meteorological Organization (I-WMO).

“Ukubuka kokuqanjwa kwezivunguvungu (izishingishane zasezindaweni ezishisayo) eyaqala eminyakeni edlule ngenhloso yokusiza ekuhlonzweni okufushane kweziphepho emilayezweni eyisixwayiso ngenxa yamagama acatshangelwa ukuthi alula kakhulu ukuwakhumbula kunezinombolo nemishwana yobuchwepheshe.,” i-WMO ichaziwe.

Uhlu lwamagama lulandelana ngezinhlamvu, iqala ngo-A isizini ngayinye; nokho, ayifaki amagama abo bonke 26 izincwadi. Izibikezelo zeqa izinhlamvu Q, U, X, U-Y no-Z ngenxa yamagama ambalwa kuphela aqala ngalezi zinhlamvu.

Ngemuva kokusetshenziswa kwegama lokugcina ohlwini, indlela lezo zivunguvungu eziqanjwe ngayo izinguquko kakhulu.

Kuyinto engavamile kakhulu ukuthi kube khona okukhulu kunalokho 21 okuthiwa izivunguvungu ngesizini eyodwa, kodwa kukhona isethi yezinkomba endaweni yomcimbi onjalo.

“Ngaphakathi kwesenzakalo lapho iziphepho ezingaphezu kwamashumi amabili nanye eziqanjwe ngokuthi tropical zenzeka phakathi nolwandle lwase-Atlantic ngesizini., izivunguvungu ezengeziwe zizothatha amagama ezinhlamvu zesiGreki,” iNational Hurricane Heart yathi.

Ngenxa yalokhu izivunguvungu ezingamashumi amabili nesibili eziqanjwe igama zingaqanjwa ngohlamvu lokuqala ngaphakathi kwezinhlamvu zezinhlamvu zesiGreki, I-Alpha, yamukelwe yincwadi yesibili, I-Beta, njalonjalo. Kukho konke, bangu 24 izinhlamvu ngaphakathi kwezinhlamvu zesiGreki ezingasetshenziswa.

Selokhu kuqanjwe iziphepho neziphepho ezishisayo kwaqala phakathi nawo-1900s, bekunonyaka owodwa nje indawo lapho bekukhona okukhulu kunalokhu 21 okuthiwa izivunguvungu ngesizini eyodwa yesiphepho.

Abangadumile 2005 Isikhathi seziphepho zase-Atlantic sidale ukuqopha umlando 28 okuthiwa izivunguvungu. Iziphepho eziningi zaqina zaba iziphepho zomlando, kanye noKatrina, U-Rita no-Wilma ngalowo nyaka. “Isizini iphawule okokuqala lapho izazi zezulu kudingeke zisebenzise izinhlamvu zesiGreki ukuze ziqambe iziphepho zasezindaweni ezishisayo.,” kusho i-WMO.

NgoJulayi, Izazi zezulu ze-AccuWeather zazikhona ukubikezela isizini yesiphepho esinamandla e-Atlantic kuze kufike 24 okuthiwa izivunguvungu, futhi leso sibikezelo siyabhekisiswa ukuze sibuyele ekugcwalisekeni.

Kuleli zinga, kunethuba elinamandla lokuthi ukuhlonza ngakunye kusetshenziswe kule nkathi yesiphepho ngemva kwalokho okunye. Izazi zezulu ze-AccuWeather sezivele zikhona umatasa uqapha izindawo ezingase zithuthukiswe kude phakathi komcengezi.

Amagama ayisithupha kuphela ahlala ukuze asetshenziswe ngaphambi kokuba izibikezelo zifake isimpompi kuzinhlamvu zezinhlamvu zesiGreki: UPaulette, Rene, Sally, Teddy, U-Vicky kanye noWilfred.

Uma i-alfabhethi yesiGreki kufanele isetshenziswe ku 2020, izohambisana nokufakwa kuhlu okufanayo njenge 2005, eqala ngo-Alpha. Lokho kufana nendlela amagama amaningi aphinde asetshenziswe ngayo ngemva kweminyaka embalwa, kuze kube yilapho inkomba isiyekiwe.

Noma kunjalo, kunomehluko omkhulu phakathi kwamagama ajwayelekile kanye nezinhlamvu zezinhlamvu zesiGreki: Izinhlamvu zezinhlamvu ze-Greek ezingase zisetshenziselwe izinhlelo ezishisayo azikwazi ukuhoxiswa.

“Uma isiphepho esikhulu esiqokwe ngohlamvu lwezinhlamvu zesiGreki, kuzo zombili i-Atlantic noma i-jap North Pacific Basin, kwakucatshangwa ukuthi ikufanelekele ‘ukuthatha umhlalaphansi,’ izofakwa phakathi kohlu lwamagama asethathe umhlalaphansi kanye nonyaka wokusabalala kanye nemininingwane ehlukene, nokho lolo hlamvu ngalunye ngaphakathi kwe-Alphabet yesiGreki luzoqhubeka lutholakale ukuze lusetshenziswe ngokushesha noma kamuva,” i-WMO ichaziwe.

Ngisho nalapho isizini yesiphepho sase-Atlantic iphela ngo-Nov. 30, kukhona nokho ithemba lokuthi uhlelo olulodwa noma ezimbili zasezindaweni ezishisayo zingase zithuthuke ngaphambi kwalokho 2020 kuhilela okuningiliziwe.

Eduze kwethiphu ye 2005, kulandela inkathi eyingqophamlando yesiphepho, I-Tropical Storm Zeta yaqala ukubonakala empumalanga ye-Atlantic Ocean ngo-Dec. 30. I-Zeta yahlala phezu kwamanzi avulekile oLwandlekazi i-Atlantic kwaze kwaba uJan. 7, 2006, ngaphambi kokuthi iphele. I-Zeta kwakuyisivunguvungu sesithupha esizonikezwa idumela kusuka kuzinhlamvu zesiGreki ngalowo yr.

Ngemva kokuba ikhalenda liphendukisela ku 2021, lesi simiso sezinto ezishisayo esilandelayo ngaphakathi kolwandle lwe-Atlantic singase sibizwe ngokuthi i-Ana.
