Isiphepho u-Irma sibonakale sisuka e-International Space Station
Irma manje sesibe ngokusemthethweni isiphepho esinamandla kakhulu emlandweni esenziwe e-Atlantic. Nabanye imimoya eqhubekayo cishe engama-300km / h, nosayizi ocishe ufane nowaseFrance, uqhubeka nokusondela kwawo kudala umonakalo omkhulu. Amandla ayo makhulu kangangokuba nama-seismographs angakubona ukuba khona kwawo. Isithinte iziqhingi zaseCaribbean i-Anguilla, i-Antigua neBarbuda. Futhi njengamanje ibheke eCuba, ePuerto Rico, naseZweni laseFlorida.
Imeya yaseMiami-Dade, uCarlos Giménez, ukuqinisekisile lokho "ISiphepho u-Irma siyisongo esikhulu eFlorida, eSouth-Dade nasendaweni yethu ikakhulukazi". Kunemiyalo yokuphuma kwabantu abaningi ezindaweni ezihlukahlukene. Futhi banikeze imephu kubantu abahlala eMiami nasezindaweni eziseduze, mayelana nezindawo zokuphuma ezisekelwe engozini yokuhlala lapho ngesikhathi sokuhamba kwesiphepho. Ngaphandle kwemimoya enamandla, izimvula ezinamandla nezikhukhula eziyingozi kulindeleke noma kuphi lapho zidlula khona.
Izimo ezinhle eziholele ku-Irma
Ngokuya ngezexwayiso zezazi zezulu, ngisho nesimo esiphuthumayo, bayakuqinisekisa lokho umthelela wayo ungaba yinhlekelele enkulu kakhulu kunalokho obekulindelekile. Isibonelo esihle nguHarvey, owaqiniswa kakhulu ngaphambi kokuwa. U-Irma, naphezu kokuba esefinyelele isimo seSigaba 5, akabonakali elandela iphethini evamile yezinye iziphepho zase-Atlantic. Ngokuvamile, lapho isiphepho sesifinyelele esigabeni esiphezulu, babevame "ukuba buthakathaka," futhi kwakuhlale kukhona uhlobo lwento engavamile. U-Irma ubekezele.
Phakathi kwezici ezifanele kakhulu, izinga lokushisa lolwandle liphakathi kuka-1 no-1ºC ngokufudumele, okwenza kube yisiphepho esinamandla. I-shear yomoya iphansi, okungukuthi, umoya ungahamba ngokukhululeka uphume uphume. Awekho amafu othuli aseSahara ajikeleza e-Atlantic, futhi kushesha ngokwanele ukuthi amanzi afudumele aphuma kulesi siphepho anomthelela ekushiseni kwawo. Ngaphezu kokuthi akakathinti phansi, zonke lezi zinto zibambe iqhaza ekusizeni u-Irma abe yilokhu ayikho.
Umbuzo osalayo, futhi osekuxoxwe ngawo muva nje, uthi: ingabe isikali se-Saffir-Simpson kuzofanele sithuthukiswe sibe yiSigaba 6? Ngaphezu kwalokho, i- Isiphepho u-Irma siyaqhubeka nokuthuthuka futhi kubalulekile ukuqaphela umkhondo wabo. Ngaphezu kwalokho, kubalulekile ukucabangela izici zesiphepho maqondana nezinye izenzakalo, njengoba kuboniswa ukuhlaziya okwenziwa Isiphepho uMaria, ukuqonda ukuziphatha kweziphepho kule sizini. Futhi, i- umlando weziphepho ezibhubhisayo isinika umongo mayelana nobukhulu be-Irma.
