Zinthu zofunika kwambiri zomwe muyenera kuzidziwa ngati chivomezi chikuchitika:
- Palibe malo omwe ali otetezeka ku mphepo yamkuntho.
- Ngati chiwonongeko chimatulutsidwa, pita kumalo otetezeka kapena pogona, monga chipinda chapansi kapena pansi pa mipando yamphamvu.
- Khalani kutali ndi mawindo.
- Ngati muli m'galimoto yanu mutatuluka chenjezo, tulutsani galimoto mwamsanga ndipo mupeze malo obisalamo.
Mvula yamkuntho, yomwe imadziwika kuti ndi mphepo yamkuntho kwambiri, imakhala yowonjezereka ku United States kusiyana ndi dziko lina liri lonse lapansi, malinga ndi bungwe la National Oceanic and Atmospheric Organization (NOAA), lomwe likugwira ntchito National Weather Service.
Ngakhale pakhala pali chimphepo chimene boma lililonse la United States linachita, mbali zina za dzikoli zimakhala zosavuta kuposa zina ku nyenyezi zamkuntho.
Kodi Chimachititsa Chimphepo N'chiyani?
Mphepo zamkuntho ziyenera kunyalanyazidwa chifukwa zingayambitse chiwonongeko chachikulu, ngakhale kuzungulira mitengo ndi kugogoda nyumba. Mphepo imatha kufika makilomita oposa 300 pa ora. Nthaŵi zambiri mkuntho imayamba mvula yamkuntho, pamodzi ndi kutentha, kutentha kwambiri ndi mpweya wozizira, wouma. Kusemphana uku kumayambitsa mlengalenga wosasunthika ndipo kumapangitsa mpweya woyendayenda womwe ukukwera pamwamba. Pamene mtambo wamtambo ngati uwu umakhudza pansi, umagawidwa ngati chimphepo.
Kum'maŵa kwa mapiri a Rocky ndi kumene mphepo yamkuntho imapezeka nthawi zambiri, makamaka m'dera lina lotchedwa Tornado Alley. Tornado Alley ikuphatikizapo Midwest States ku Iowa, Kansas, Missouri, Oklahoma, ndi Nebraska, komanso dziko lakumwera la Texas. Osaphatikizidwira mkati mwa Tornado Alley komanso amadziŵika chifukwa cha ntchito yamkuntho yolimba ndikummwera chakum'mawa kwa Mississippi, Georgia, ndi Florida.
Mapu ali pamwambawa amasonyeza mbiri ya pachaka ya mvula yamkuntho ku United States, ndi chikasu choimira mapiri okwera 1 mpaka 3 omwe amafotokozedwa pachaka, omwe amaimira malalanje 3 mpaka 5 omwe amawafotokozera pachaka, ndipo wofiira amaimira chaka chilichonse cha nyenyezi zisanu ndi ziwiri mpaka 10.
Pakhala mvula yamkuntho yomwe imapezeka mwezi uliwonse pachaka, koma nyengo yachisanu ndi chilimwe ndi nyengo pamene zivomezi zimachitika nthawi zambiri.
Nthawi Yachidule ya Chiwombankhanga Ntchito
- Southern Southern : March mpaka May
- Kum'mwera chakum'mawa : June mpaka August
- Madera akumadzulo: April mpaka June
- Mayiko akumadzulo: May mpaka July (kupatula ku California, komwe nyengo imayamba kuyambira Januari mpaka April)
Onani mndandanda wa miyezi yambiri ya chiwombankhanga chomwe chikuchitika.
Kodi Kusiyanitsa Pakati pa Tornado Watch ndi Tornado Chenjezo?
Nyuzipepala ya National Weather Service imatanthauzira ulonda wamkuntho monga tanthauzo: "Mphepo zamkuntho zimapezeka m'dera lanu. Khalani maso kuti muyandikire mvula yamkuntho."
Nyuzipepala ya National Weather Service imatanthawuza chenjezo la chimphepo monga tanthauzo: "Mphepo yamkuntho yakhala ikuwonekera kapena ikusonyezedwa ndi nyengo yamkuntho. Ngati chiwonetsero cha mvula yamkuntho chikuperekedwa kwa dera lanu ndipo mlengalenga zikuwopseza, pita kumalo anu osungirako kale."
Pali zowonongeka ndi zachilengedwe kuti zikuchenjezeni kuti kuthekera kwa chimphepo. Iwo ali, molingana ndi NOAA:
- Mdima wakuda, nthawi zambiri wobiriwira
- Mtambo wamtambo
- Chipilala chachikulu
- Kulira mofuula; zofanana ndi sitima yonyamula katundu
Mukhozanso kuyang'ana pa wailesi yakanema ndi wailesi, pamene nkhani za National Weather Service zimapereka zilengezo pawotchi kapena kuchenjeza ngati "kukwawa" kapena mayesero a Emergency Broadcasting System. Apo ayi, pulogalamu yamakono yamapulogalamu yamapulogalamu omwe amatha kutulutsa zidziwitso zokakamiza, monga ufulu wa Weather Weather, ndi yabwino.
Kodi Zina mwa Zivomezi Zowonongeka Zakale M'mbiri Yaka US?
- "Tri-State Tornado" inapha anthu pafupifupi 700 ndipo inavulaza oposa 2000 mu March 1925, akudutsa kudutsa Missouri, Illinois, ndi Indiana.
- "Natchez Tornado" anayenda mumtsinje wa Mississippi ku Louisiana ndi Mississippi mu 1840 akupha anthu oposa 300.
- "The St. Louis Tornado" inachitika mu 1896 ndipo mphepo zakhala zikufika makilomita 260 pa ora. Anthu oposa 250 anaphedwa anthu 255 ndipo anthu pafupifupi 1000 anavulala.
