Kanye xa wonke umntu esenayo le nto iziphumo ezishiye iNkanyamba uHarvey njengoko yayidlula eTexas, inkanyamba entsha, eyabhaptizwa ngegama lika Irma, usiya kwiCaribbean. Ngethuba lokufikelela eUnited States, yeyenkanyamba eyaziwayo ebizwa ngokuba yi “Cape Verde hurricane”.
Ezi ntlobo zeenkanyamba zibizwa njalo kuba zenzeka kwimpuma yeAtlantic, kufutshane neziqithi zeCape Verde. Ukuhamba ngaphesheya kweAtlantic, iCape Verde cyclones bakholisa ukugqama ngokuba zezona nkqwithela zinkulu nezizezona zinamandla. Imizekelo yoku ingafunyanwa yiNkanyamba uHugo, eyafikelela kwinqanaba 5, eyathi yanefuthe ePuerto Rico, eSaint Croix naseMzantsi Carolina, ishiya umonakalo omkhulu ngo-1989. Omnye umzekelo yiNkanyamba u-Iván ngo-2004 kudidi lwesi-5. Ubuninzi "obungenakuthelekiswa nanto" kwiindawo eziphantsi ezinemimoya ephezulu ye-275km / h.
Irma sisiphepho esinokubhubhisa
Iqhwithi iIrma ngoku
U-Irma wabizwa njengesaqhwithi esikweleenjiko ngale ntsasa yangoLwesithathu. NgoLwesine emva kwemini, yayisele iliqhwithi lodidi 3, kunye nemimoya ye-185km / h. Oku kuqiniswa kuqhushumbo kuyaziwa ngokuba "kukukhula ngokukhawuleza.", njengoko kuchaziwe yifayile ye- IZiko leNkanyamba leLizwe. Eli gama linikezelwa xa kukho ukwanda kwesantya somoya ubuncinci abangama-56km / h kwisithuba esingaphantsi kweeyure ezingama-24.
Kwimeko kaHarvey, siyayibona kwa le nto inye. Kwakunokunyuka okukhawulezileyo ngaphambi kokwehla komhlaba, ukuyinyusela kwinqanaba 4 xa yayisondela eCorpus Christi. Nangona kunjalo, nangona bekulindelwe ukuba ingonyuka, bambalwa ngebengathi iyakufikelela kumandla amakhulu ngaphambili, xa bekulindelwe ukuba ingafikelela kwinqanaba 1, ubukhulu becala. Ngamanye amaxesha, izinto zomzuzu wokugqibela zibangela utshintsho olukhulu , zombini kwinkanyamba nakwezinye iimeko zemozulu.
Kwi-Irma, uqikelelo lwangoku kunye nolusemthethweni oluvela kwiZiko leNkanyamba leLizwe libonisa oko iya kuqhubeka isomelela njengoko usiya entshona kwiintsuku ezintlanu ezizayo. Kunokwenzeka ukuba ngalo Lwesibini, ibe sele iza kuba yinkanyamba yodidi 4. Eli candelo, kwisikali seSaffir-Simpson, liquka isantya somoya esiphakathi kwama-210 nama-249km / h, noxinzelelo oluphakathi oluphakathi kwama-milligrars angama-920 nama-944. Umonakalo onokubakho ugcwele kwizakhiwo ezikhuselayo, ukuwa kophahla kwizakhiwo ezincinci, kunye nezikhukula kwindawo yangaphakathi, efana neHarvey.
Uqikelelo lukaIrma lwangoLwesine olandelayo umhla we-7
IPuerto Rico ilungiselela
Nangona kungenakwenzeka ukwazi ngokuthe ngqo ukuba iNkanyamba u-Irma izakufika ePuerto Rico, umasipala wesiqithi waseCulebra sele elungiselela, ecinga ukuba kuyakwenzeka. USodolophu uWilliam Iván Solís uthe, «Asinakuthembana. Sikhuthaza abantu ukuba bazilungiselele. Masingalindi kude kube ngumzuzu wokugqibela ». Kwangokunjalo, usodolophu ubonakalisa ukuba ukuba inkanyamba ihlasela ePuerto Rico, iindawo ezinamakhaya ezindlu ezenziwe ngomthi nezinc, kunye namakhaya ahambahambayo, aza kugxothwa.
Ukuthathela ingqalelo uqikelelo lweZiko leNkanyamba leSizwe, I-Irma ingadlula ngasemantla ePuerto Rico phakathi koLwesithathu nangoLwesine weveki elandelayo njenge "nkanyamba enkulu." Ngomoya ongaphezulu kwe-178km / h osele uluhlobo 3. "Ukuze inhlekelele ingenzeki, siza kuyilungisa njengoko silungiselela unyaka nonyaka", USolís ugwetyelwe.
Ngubani obiza iinkanyamba?
Unyaka noluhlu luyenziwa kunye namagama eziza kufunyanwa ziziqhwithi eziza kubakho kulo lonke ixesha lonyaka. Olu luhlu luphindaphindiweyo qho emva kweminyaka emi-6, kubandakanya igama loonobumba ngamnye woonobumba (ngaphandle kokubala oonobumba u-Q, U, X, Y no-Z) kunye namanye amagama obudoda nawabafazi. Kulo nyaka umzekelo, ixesha lenkanyamba laqala ngo-Arlene, ngo-Epreli, eqala igama ngo-A.Harvey, owayengu-H, unobumba olandelayo wayeza kuba ndim, kungoko u-Irma elandelayo.
Xa inkanyamba yonakalisa kakhulu elizweni, igama layo liyarhoxiswa lize lifakwe kuluhlu. Kananjalo igama lakho alinakusetyenziswa kule minyaka ili-10 izayo ukunqanda ukudideka. Ngale ndlela, ngokubiza inkanyamba ngegama, inokufumaneka ngokukhawuleza ngexesha. Le nkqubo yenziwe ngo-1953 liZiko leNkanyamba leLizwe, eUnited States.
Siza kunika ingxelo ngayo nayiphi na into eyenzekayo ku-Irma.
