INkanyamba uDorian

Inkanyamba dorian

Siyazi ukuba utshintsho lwemozulu luyonyusa ukuphindaphindeka kunye nokuqina apho kwenzeka khona iimeko zemozulu zoluhlu olungaqhelekanga. Kule meko, siza kuthetha INkanyamba uDorian. Yenzeka ngoSeptemba 2019 kwaye yadweliswa njengodidi 5. Eli nqanaba lelona liphezulu. Kubangele iintlekele ezinkulu kwaye kwasifundisa utyekelo lokutshintsha kwemozulu ukwenza rhoqo ezi ntlobo zeziganeko zemozulu ezibi.

Ke ngoko, siza kunikezela eli nqaku ukukuxelela yonke into ekufuneka uyazi ngeNkanyamba iDorian, iimpawu zayo kunye neziphumo zayo.

Iimpawu eziphambili

Inkanyamba yokuma dorian

Isikali sikaSaffir-Simpson yinkqubo yokulinganisa inkanyamba. Yahlulwe yangamacandelo ama-5, athathela ingqalelo isantya somoya kunye nomsebenzi wecyclonic emva kwenkanyamba, kwaye athabathela ingqalelo ukunyuka okungaqhelekanga kwinqanaba lolwandle emva kwezaqhwithi. INkanyamba uDorian yafikelela kwinqanaba 5, eyeyona inkulu kwaye iyingoziNangona icothisile ukufika kwayo eBahamas, yabangela ukonzakala okukhulu kunye nokufa kwabantu abahlanu.

Makhe sibone ukuba isantya somoya sixhomekeke kudidi:

  • Udidi 1: Imimoya phakathi kwe-118 kunye ne-153 KM / iyure
  • Udidi 2: Imimoya phakathi kwe-154 kunye ne-177 KM / iyure
  • Udidi 3: Imimoya phakathi kwe-178 kunye ne-209 KM / iyure
  • Udidi 4: Imimoya phakathi kwe-210 kunye ne-249 KM / iyure
  • Udidi 5: Imimoya engaphezu kwama-249 KM / iyure

Umkhondo weNkanyamba uDorian

I-Bahamas njengethagethi

Xa kwafunyanwa iNkanyamba uDorian, iZiko leNkanyamba leLizwe lamangaliswa "kukungaqiniseki kuqikelelo lwendlela" yenkanyamba. IZiko leNkupho leSizwe licinga ukuba ngenxa yoluhlu olubanzi lwezisombululo zemodeli, ukuthembeka koqikelelo olunamandla kwakusezantsi. Kufuneka iqatshelwe ukuba iinkanyamba ezinobushushu ezifana neDorian zihlala kunzima ukuqikelela.

UDorian wayenethuba lokuxhobisa amandla okupompa, ngakumbi kuba uthuli oluvela eSahara lwafikelela kuLwandle lweCaribbean kwaye lucothisa ukukhula kwalo. Nale nto ibangela ukuba ububanzi benkanyamba bujikeleze phakathi kwe-35 km kunye ne-75 km. Ukusuka kwinxalenye yokuqala, lo mzila ubonakalisile ukuba udlule ePuerto Rico nakumantla mpuma eDominican Republic. Abanye bade baxela kwangaphambili ukuba inokufikelela emantla eCuba. Kodwa wamangaliswa kwakhona, eshiya iimvula ezimbalwa ePuerto Rico. Ekugqibeleni, yaya ngasemantla ntshona yaza yafikelela eBahamas naseFlorida eUnited States.

I-panorama eyashiywa nguDorian kwiziqithi zeBahamas yayimfiliba. Ubuncinci i-5 iswelekile kwaye ingaphezulu kwe-20 yenzakele. Ngokwengxelo ye-International Red Cross, ekhutshwe ngoMvulo, nge-2 kaSeptemba 2019, ngaphezulu kwe-13 lamawaka ezindlu zonakaliswe kakhulu kwaye ezininzi zatshatyalaliswa ngqo. Ukongeza, izikhukula zabangela iziQithi i-Abaco, iqela leecays kumantla ntshona eBahamas. Imithombo yamanzi okusela yayingcoliswe ngamanzi anetyuwa.

Iinkonzo ezichaphazelekayo yiNkanyamba uDorian

EUnited States, Ukuhamba kwenkanyamba kuchaphazele iinqwelomoya ezingaphezu kwama-600. Ngenxa yokufika kwenkanyamba, izikhululo zeenqwelo moya eOrlando, Daytona Beach, Fernandina Beach, Jacksonville nasePompano Beach ziya kuhlala zivaliwe kude kube Lwesithathu. Ukongeza, amazibuko aseFlorida nawo ayekile ukubonelela ngeenkonzo kwaye noololiwe bamiswa. E-Georgia, South Carolina nase North Carolina, bonke abahlali ababehlala empuma ye-I-95 bakhutshwa ngenxa yezikhukula.

Inkanyamba yayikho eBahamas iiyure ezili-18. Yayiyiphupha elibi ngokwenene. Nangona bekulindelwe ukuba icothe kwaye imise, bambalwa kakhulu abalindeleyo ukuba iyeke ngaphezulu kweBahamas ukuba ihlale ixesha elide.

Ukusukela ngemva kwemvulo yangoMvulo, uDorian wahlala phantse kwindawo enye kude kube ngesiphelo ngoLwesibini, xa wayeqala ukuhamba umantla ntshona ngesantya sofudo: 2 km / h ethe kamva yenyuka yaya kwi-7 km / h.

Inkanyamba

Inkanyamba notshintsho lwemozulu

Ngokwenzululwazi kukho imeko ephazamisayo evela kutshintsho lwemozulu. Izitshingitshane zaseTropiki ziye zakwazi ukuyeka kufutshane nonxweme kwaye zichithe iiyure ezininzi kule mimandla. Ngokucacileyo le yinyani ephazamisayo, kuba iziphumo ezibi ezixekweni ziya kubonakala ixesha elide. Ngokwezifundo, Isantya esiphakathi senkanyamba sehle nge-17%, phakathi kwe-15,4 km / h kunye ne-18,5 km / h.

Inyaniso yokuba inkanyamba iyema kwindawo ethile kuthetha ukuba umonakalo kuloo ndawo uya kunyuka kakhulu. Kungenxa yokuba umoya nemvula zichaphazela le mimandla ixesha elide. Umzekelo, uHarvey wathulula ngaphezulu kwe-1.500 yeemilimitha zemvula ngaphezulu kweHouston emva kokuba ebekhona kangangeentsuku ezininzi. Iqhwithi uDorian labetha iBahamas ngomsinga wamanzi angamashumi amabini eenyawo kunye nemvula ngaphezulu kweeyure ezingama-48.

Izizathu

Ngokwezifundo, kwisiqingatha senkulungwane sokugqibela, zonke izivunguvungu eziye zayeka okanye zacotha zinesizathu esikhethekileyo. Isizathu sihambelana nokudodobala okanye ukuwa kweepateni zomoya omkhulu. Nangona kunjalo, le meko kukholelwa ukuba ibangelwe kukuhla kancinci kokujikeleza kwemozulu (Umoya wehlabathi), wenza iinkanyamba kwiindawo ezitshisayo kwaye usiya ngasezibondeni kwiziphakathi eziphakathi.

Izaqhwithi azihambi ngokwazo: ziqhutywa yimisinga yomoya yehlabathi, ethi ichukunyiswe yimithamo yoxinzelelo emoyeni.

Zimbalwa iingcali ezilithandabuzayo ifuthe lobushushu behlabathi kwizitshingitshane ezikweleenjiko. UPhilip Klotzbach, ingcali ngemozulu kwiYunivesithi yaseColorado State eMelika, uthe abukho ubungqina bokuba ukutshintsha kwemozulu kubangela iinkanyamba ezininzi, kodwa bukhona ubungqina bokuba utshintsho lwemozulu lubangela iimeko zokuba batshabalalise ngakumbi. Umzekelo, UDorian sisigaba sesihlanu senkanyamba ukwenza iAtlantic kwiminyaka nje emine, ingxelo engenakuthelekiswa nanto. Umoya ofudumeleyo unokugcina ukufuma okungakumbi kwaye ke oku kuzisa imvula eninzi. Ngapha koko, ngokunyuka kwamanqanaba olwandle, uqhwithela ludlulela ngaphakathi elizweni, njengoko ulwandle luphezulu.

Ndiyathemba ukuba ngolwazi olunje ungafunda ngakumbi ngeNkanyamba iDorian kunye neempawu zayo.
