I-Tornado Izixwayiso, ama-Watches, Ukulungela, ne-Historical Tornado Information
I-Minneapolis noSt. Paul, njengamanye amazwe ase-USA, basengozini yokuvela ezinkantanini. I-Southern Minnesota, kuhlanganise ne-Twin Cities metro endaweni, ithathwa njenge-Tornado Alley, kanti i-Twin Cities iphakathi kwamadolobha ama-15 aphezulu kakhulu amathuba okushaywa yisiphepho.
Izinkanyamba zingabhubhisa, kodwa ungakwazi ukunciphisa kakhulu ingozi kuwe nabathandekayo ngokuzilungiselela, nokwazi ukuthi yini okufanele ukwenze uma isiphepho sishaya.
Iningi lokufa nokulimala kwenzeka kubantu abathintekayo. Eziningi zenzeka kubantu abazwa izixwayiso zenkathazo, kodwa bangazinaki.
Iziphi Izinkanyamba Zenzeka NgaseMinneapolis naseSt. Paul?
Isikhathi sezulu esiyingqungquthela saseMinneapolis neSt. Paul ngoMeyi, ngoJuni noJulayi. Kodwa-ke, izimpungushe zingenza futhi zishaye ngaphandle kwalezi zinyanga. Esikhathini esidlule, iziphephozi ziye zamshaya eNigeria njalo ngenyanga kusuka ngoMashi kuze kuNovemba.
Ngizokwazi Kanjani Ukuthi I-Tornado isondela?
Buka isimo sezulu, futhi uqaphele ukubukwa kwesiphepho, izixwayiso zenkanyamba, kanye nezikhala eziphuthumayo.
Izindlebe eziphuthumayo zangaphandle , ezivame ukubizwa ngokuthi i-tornado sirens, zizwakala lapho kuqhamuka isiphepho. Ama-sirens azwakala lapho iNational Weather Service isusa isixwayiso sezulu. Zizwakala futhi uma isiqhwithi sibonakala ngendawo eqeqeshiwe, umshayeli wokushisa umlilo noma isikhulu samaphoyisa, noma uma ukubonwa yilungu lomphakathi kuqinisekiswa.
I-Sirire itholakala kuwo wonke amadolobha aseTwin.
Kodwa ungacabangi ukuthi ngenxa yokuthi ayikho i-siren, ayikho ingozi.
Ngenkathi kunezikhalazo eziphuthumayo zangaphandle ezingasemadolobheni amaTwin, kungenzeka ukuthi azizwanga zonke izinkanyamba. Lapho i-tornado ebhubhisa i-Siren, ngesi-Wisconsin, ngesineke, ngo-2001, ayikho i-siren ephuthumayo eyabhalwa. I-siren yaphulwa, futhi noma ngabe isebenza, amandla aphelile futhi i-siren, njengabaningi e-Wisconsin naseMinnesota, ayinayo ibhethri yokulondoloza.
Izinkanyamba zingakha ngokushesha kakhulu, kwezinye izimo ngokushesha kakhulu ukuze izinsimbi zizwakale ngesikhathi.
Lapha emaDolobheni amaTwin, izinsimbi zeHennepin County azizwanga ku-2006 Rogers Tornado, eyabulala intombazane eneminyaka eyishumi ubudala. I-National Weather Service ithi isimo sezulu esivumelanisiwe nesishukumiselekayo sasho ukuthi kwakungekho isikhathi sokuzwakala izinhlabamkhosi ngaphambi kokuba isiphepho siphethe edolobheni laseRogers nasenyakatho yeHennepin County.
Uma izinhlabamkhosi eziphuthumayo zizwakala, azizwakali yonke indawo.
Izikhalazo eziphuthumayo zangaphandle zenzelwe ukuzwakala ngaphandle, futhi abantu ezakhiweni bangase bangazizwa. Ngiyakwazi ukuzwa kuphela izinhlabamkhosi ezivivinywa ngokungahlali ekhaya, futhi angikwazi ukuzwa izinhlabamkhosi nhlobo esitolo noma isakhiwo esikhulu.
Ngakho izinhlabamkhosi zingase zingasebenzi, zingase zingazwanga ngesikhathi, futhi uma zenza, ungase uzizwe. Ngakho kubalulekile ukubukela isimo sezulu futhi. Abaningi abahlali beTwin Cities banomkhuba wokuhlola njalo isimo sezulu emsakazweni, kumabonakude, ephephandabeni noma kwi-intanethi, futhi kuwumkhuba ohlakaniphile wokuwamukela.
Qaphela ukuthi kwenzekani ngaphandle, ikakhulu uma isimo sezulu siphenduka. Lalela ukubukwa kwe-tornado nokuxwayisa kwithelevishini yendawo noma umsakazo.
Yiziphi Izimpawu Zesimo Sezulu Ezibonisa Indwangu Yomlilo?
Lezi ezinye izibonakaliso ezibonakalayo okufanele zithathwe njengesixwayiso sezulu eliqhamukayo,
- Isibhakabhaka esiluhlaza noma esibomvu
- Ifu elibunjwa ngamapulangwe
- Ifu eliphansi, elimnyama
- Ukuthungwa ngothuli noma imfucumfucu, ama-debris awela noma ahanjiswa phezulu
- Dumisa, ukuduma noma umbani
- Ukuziphatha kwamafu we-Strange, afana namafu ahamba ngokushesha kakhulu, esheshayo noma eguquguqukayo
- Ukwehla okusheshayo kokushisa
- Ukuzola ngokuzumayo emva komoya, lapho umoya uhlala kakhulu
I-Tornado ofakazi bavame ukubika ukuthi "bazizwe" beza ngaphambi kokuba kuqhume isiphepho. Izinkanyamba zihlotshaniswa nomfutho ophansi womoya, umzimba ongawuqonda. Uma umzimba wakho ukutshela ukuthi kukhona ingozi, kungaba ukuhlakanipha ukulalela.
Nakuba zifana nezinkanyamba zabantu abaningi, umbhobho ungase ungabonakali noma ungabonakali. Akuzona zonke izinkanyamba ezinomkhuhlane obonakalayo. Imisebenzi ingahle ifakwe futhi ifihlwe ngothuli noma imvula.
Izinkanyamba zingakwazi, kodwa hhayi njalo, zenze umsindo. Imisindo eyenziwe ichazwa ngokuthi i-roaring, noma into efana ne-jet injini, isitimela sezimpahla, noma amanzi aphuthumayo.
ImiSebenzi ingenza futhi imisindo yokugcoba noma yokugubha. Umsindo awuhambanga kude, ngakho-ke uma uzwa isiphepho, sisondele kakhulu. Funa indawo yokuhlala ngokushesha .
I-Tornado Watches and Tornado Izixwayiso
I-National Weather Service ikhipha izixwayiso zokubuka izikhukhula kanye nezixwayiso zesiphepho. Uyini umehluko?
I-Tornado Watch : I-watch ibonisa ukuthi izimo zithandeka ekwakheni izinkanyamba, kodwa akukho nhlanhla yangempela ibonwe yizintambo noma ingabonwa ku-radar yedoppler. Lalela imibiko yendawo yesimo sezulu, unake isimo sezulu, futhi ulungele ukuzivikela uma kunesidingo. Qaphela abangane, umndeni, kanye nomakhelwane wesixwayiso.
I-Tornado Isexwayiso : Isixwayiso sisho ukuthi isiphepho sitholiwe, noma i-doppler radar ibonisa isivunguvungu sakha noma sakha.
