Ama-cyclone aseTropical, okuthiwa nama-typhoons noma (lapho aqinile kakhulu) iziphepho kwezinye izingxenye zomhlaba, kuneziphepho zomoya nemvula eningizimu yezwe elibhekene nokucindezela okuphansi kwesibhakabhaka esiphakathi (iso lesiphepho) kanye nokunyakaza kwesimo sezulu. Enyakatho ye-hemisphere, imimoya iyajikeleza nge-clockwise.
Ama-Cyclone aseTropical e-Australia
E-Australia, ama-cyclone asezindaweni ezishisayo anqunywe ngokuvumelana nesisindo somoya kanye nobubanzi kusukela esigabeni 1 esibuthakathaka kuya esigabeni 5 esilimazayo kakhulu.
I-Cyclone Tracy kungenzeka imicimbi ye-cyclone edumile kakhulu futhi ebulalayo yase-Australia. Lichitha inhloko-dolobha yaseNorthern Territory yaseDarwin phansi ngo-1974 futhi yabulala abantu abangu-65, ilimaza abantu abangu-145 ngokungathí sina futhi abangaphezu kuka-500 abahlukumezekile okuncane.
I-Cyclone Tracy yalinganiselwe isiphepho seSigaba 4. Yenza umonakalo ekubalukeni kwe $ 800 million ngo-1974 amadola ase-Australia.
I-cyclone eyingozi kunazo zonke ukushaya u-Australia kwenzeka ngo-1899 lapho abantu abangaphezu kuka-400 befa ngesikhathi isivunguvungu sishaya eKapa. Le mkhuhlane, eyabhubhisa izikebhe eziyikhulu zokudoba eziseChristal Charlotte Bay, yayingakaze ihlukaniswe futhi ibonakala ingazange ibhalwe ngamagama.
Eyodwa yezindawo ezihamba phambili ze-cyclone e-Australia yisifunda seNtshonalanga Australia. Ugu olusenyakatho-ntshonalanga ngaphakathi eNtshonalanga Australia yindawo evamile kakhulu yezikhukhula ezizokwenzeka ngaphakathi kwesizwe sethu ngenxa yokushisa kwamazinga okushisa okuholela emoyeni ofudumele nolomanzi ukuyoklama.
Uma inhlanganisela yemimoya enamandla ephilile, ishintshe ngesivunguvungu somoya, futhi umswakama ongezingeni eliphansi kwenzeka khona lapho isiphepho
Isikhathi sezulu se-Australia
Isikhathi sezulu lesiphepho esifundeni seTropiki sase-Australia sivame ukuqala kusukela ngo-1 Novemba kuya ku-30 ka-Ephreli. Njengoba isilinganiso sama-cyclone angu-10 ngonyaka sathuthuka ezindaweni ezifana ne-Exmouth noBroome ngasentshonalanga, futhi kude nasenyakatho yeQueensland empumalanga, inkathi yesivunguvungu ingaba nzima kakhulu.
Nakuba ama-cyclone angase abe indawo evamile ezindaweni ezibandayo zase-Australia uma kuqhathaniswa neMelika izinga liphansi kakhulu. Ngaphandle kwalokhu, iqiniso lokuthi bambalwa kakhulu abakwenzayo ogwini noma ukwenza umhlaba libuye lenze izinto zibukeke.
Ingabe Iziphepho Zase-Australia Zingozi?
Lapho uhambela izingxenye ezishisayo zase-Australia, kuphakanyiswa ukukhumbula ukuthi yiziphi izindawo ezithintekayo kuma-cyclone, isilinganiso esenzeka kuzo emazweni athile nokuthi yiziphi izimo ezisiza ekwakheni isimo esingaguquki.
Noma kunjalo, ama-cyclone akuyona inkinga enkulu e-Australia ukuze ucabange ukulibala noma ukushintsha izinhlelo zakho zokuhamba ngenxa yokubonakala kwazo.
Ama-cyclone enza ukuthi kungenakwenzeka ukufika phansi futhi uma kwenzeka, iziphathimandla zase-Australia zilungele ukubhekana nesenzakalo esinjalo. Ama-cyclone amaningi amakhulu ashaye ogwini olusentshonalanga nasogwini olude olusenyakatho yeQueensland, njenge-Cyclone Yasi ngo-2011 kanye ne-Cyclone Ita ngo-2014.
Nakuba lezi zenzakalo zezulu zenza umonakalo omkhulu wezigidi zamabhiliyoni - futhi ngokudabukisayo, i-Yasi yabangela ukuba amanani ebhanana akhuphuke okwesikhashana amanani abo ajwayelekile - adala ukulimala okungenani kanye nokufa.
Uma kwenzeka uzithola usondelene ne-cyclone, qiniseka ngokukwazi ukuthi i-Australia inezinyathelo eziningi zokuphepha ukuqinisekisa ukuthi abantu abaseduze nezindawo ezithintekile bazogcinwa bephephile.
Izigaba ze-Cyclone yase-Australia
Ulwazi olulandelayo lwesigaba sephepho lusekelwe ku-Australian Bureau of Meteorology Data.
- Isigaba 1 esinomoya oqine kakhulu olinganiselwa emakhilomitha angaba ngu-125 ngehora. Ngokuvamile kubangele ukulimala komzimba okungasetshenzisiwe kodwa kungabangela ukulimala kwezitshalo ezithile, izihlahla, amakholaji, kanye namanzi.
- Isigaba 2 esinomoya oqine kakhulu olinganiselwa ku-125-170km / h. Kungabangela umonakalo wendlu encane kodwa umonakalo omkhulu embonisweni, emithini nasemaphandleni, nasekulimaleni okukhulu kwezitshalo ezithile. Kungaba khona ubungozi bokuhluleka kwamandla kanye nobuciko obuncane bungase buphule ama-moorings.
- Isigaba sesi-3 esinomoya oqine kakhulu silinganiselwa ku-170-225km / h. Kungabangela ukuphahla nokulimala kwesakhiwo, ukubhubhisa amakhansela, kubangele ukuhluleka kwamandla.
- Isigaba 4 esinomoya oqine kakhulu silinganiselwa ku-225-280km / h. Kungabangela ukulahlekelwa okuphawulekayo kokuphahlazeka nokulimala kwesakhiwo, ukungcola okubangelwa yizinto eziyingozi, ukusabalalisa kwamandla okubanzi.
- Isigaba 5 esinomoya oqine kakhulu kunama-280km / h. Kubungozi kakhulu futhi kubangela ukubhujiswa okubanzi.
