Izinto ezibaluleke kakhulu oza kufuneka wazi kwiimeko zenkqantosi:
- Akukho ndawo ikhuselekile kwiinkwenkwezi.
- Ukuba kunikezelwa isilumkiso sesithwathwa, hamba kwindawo ekhuselekileyo okanye kwindawo yokukhusela, njengento encinane okanye phantsi kwefenitshala enamandla.
- Hlala kude kwiifestile.
- Ukuba usemotweni yakho xa kukhutshwa isilumkiso senqabana, phuma imoto ngokukhawuleza uze ufune indawo yokukhusela.
Iziqhwithi, ezibhekwa njengeziqhwithi ezinobundlobongela, ziqheleke kakhulu eUnited States kunezinye ihlabathi ehlabathini, ngokweNational Oceanic and Atmospheric Organisation (NOAA), eqhuba iNkonzo yeSizwe yeMozulu.
Nangona kubekho ingqungquthela ebhalwe kuyo yonke imimandla yase-US, ezinye iindawo zelizwe zithandeka ngakumbi kunabanye kwiinkanyamba.
Yintoni Ebangelwa Isiqhwithi?
Iinyenywa kufuneka zithathwe ngokungathí sina kuba zinokubangela ukubhujiswa okukhulu, kwanokuqhaqha imithi kunye nokubetha izakhiwo. Imimoya ingafikelela kumawaka angama-300 ngeyure. Iindudumo zivame ukuqala iindubhu ezininzi, kunye nokubambisana okufudumalayo, umoya omninzi ngomoya opholileyo, omile. Oku kudibanisa kubangela umoya ongenakulinganiswa kwaye kudala umphumo wokujikeleza emoyeni okhulayo. Xa ilifu le-funnel lifana nale lichaphazela phantsi, lihlelwe njengeqhwitha.
Ummandla weMpuma weeRayy Mountain apho iindawo eziqhankqalazo zihlala zihlala khona, ngokukodwa kwindawo ephantsi ebizwa ngokuba yiTornado Alley. I-Tornado Alley iquka iMidwest States yase-Iowa, iKansas, eMissouri, e-Oklahoma, ne-Nebraska, kunye nommandla wasezantsi waseTexas. Akufakiwe kwi-Tornado Alley kodwa kwaziwa ngokuba ngumsebenzi onqabileyo we-kornado yi-Southeastern states yase-Mississippi, eGeorgia naseFlorida.
Imephu engenhla ibonisa imibiko yonyaka yeengqungquthela e-United States, ephuzi emele i-1 kuya kwe-3 iindwendwe ezixeliweyo ngonyaka, i-orange emele i-3 kuya kwe-5 iindwendwe ezixeliweyo ngonyaka, kwaye ibomvu emele i-kornadoes ezi-5 ukuya kwe-10 zibikwe ngonyaka.
Kukho iqhwithi elibhalwa kwinyanga nganye yonyaka, kodwa entwasahlobo kunye nehlobo zihlobo zonyaka xa iimeko ezinkanyamba zenzeka rhoqo.
Ixesha lePherak for Activity Tornado
- Amazwe aseMzantsi : ngoMatshi ukuya ngoMeyi
- I-Northeastern States : ngoJuni ngo-Agasti
- AmaMantla aseMantla: I-Epreli ngoJuni
- Amazwe aseNtshona: NgoMeyi ukuya kuJulayi (ngaphandle kweCalifornia, apho ixesha liqhubeka ukususela ngoJanuwari ukuya ku-Apreli)
Khangela le mephu yeenyanga zentshukumo ye-crornado.
Yintoni eyahlukileyo phakathi kwe-Tornado Watch kunye neSilumkiso?
I-National Weather Service ichaza umlindo wekratshidi njengentsingiselo: "Iingqungquthela ziyakwenzeka kwindawo yakho. Hlalani niqaphele ukufika kweziphepho."
I-National Weather Service ichaza isilumkiso esinokuthi: "Ingqungquthela ibonwe okanye iboniswe yi-radar yemozulu. Ukuba isilumkiso senkqantosi sinikezelwa kwindawo yakho kwaye isibhakabhaka sisongela, hamba kwindawo yakho ekhuselekileyo."
Kukho iziqalo zokusingqongileyo kunye nokuphicothwa ukuba ziqaphele ukuba kwenzeke ingqungquthela. Baye, ngo-NOAA:
- Ubumnyama, obuninzi bubhakabhaka obuhlaza
- Ifu lefu
- Isichotho esikhulu
- Ukuduma okukhulu; kufana nesitimela somthwalo
Ungakwazi ukudibanisa kumabonwakude nakwi-radiyo, njengemiba yeSizwe yeNkonzo yezeMimoya izaziso xa kwenzeka umlindo okanye isilumkiso ngendlela yeendaba "ukukhahlela" okanye uvavanyo lweNkqubo yokuLawulwa kweMeko. Ngaphandle koko, i-app ye-smartphone enokukwazi ukukhupha izaziso ezichukumisayo, ezinjengokukhululeka kwi-Channel Weather, ilungile.
Ziziphi ezinye zeenkqantosi ezibhubhisayo kwiMbali yase-US?
- "I-Tri-State Tornado" yabulala abantu abangaba ngu-700 kwaye yalimala ngaphezu kwe-2000 ngaphezulu ngo-Matshi ka-1925, idlula eMissouri, e-Illinois nase-Indiana.
- "I-Natchez Tornado" yahamba kuMlambo waseMississippi eLouisana naseMississippi ngo-1840 ngokubulala abantu abangaphezu kwama-300.
- "I-St Louis Tornado" yenzeke ngowe-1896 kwaye iimoya zange zifike kwii-260 ngeekota. Abantu abangaphezu kwama-250 babulawa abantu abangama-255 kunye nabantu ababalelwa ku-1000 bengozi.
