Tornado mukoto zvinoreva nzvimbo iri pakati peUnited States inogaroitika chamupupuri. Munharaunda iyi, madutu anoitika kana mweya wakanyorova kubva kuGulf of Mexico ukasangana nemhepo inotonhora, yakaoma kubva kuCanada. Kunyangwe iyo nzvimbo inotsanangurwa seTornado Alley isina miganhu yakajeka, inosanganisira iyo Great Plains nyika dzeTexas, Kansas, Oklahoma, Iowa, Nebraska, uye South Dakota. Dzimwe nyika dzinombosanganisirwa munharaunda yechamupupuri dzinosanganisira Ohio, North Dakota, Arkansas, Montana, uye Indiana, pakati pevamwe. Kunyangwe dunhu richisangana nechamupupuri gore rose, mazhinji anoitika muchirimo nemuchirimo uye anowanzo kuperekedzwa nemabhanan’ana.
Muchinyorwa chino tichakuudza zvese zvaunoda kuti uzive nezve Alley chamupupuri, izvo zvinokonzeresa zvavanazvo uye humwe hunhu hukuru pamusoro pechamupupuri.
Chii chinonzi chamupupuri
Chamupupuri ihombe yemhepo inoumba neakanyanya angular velocity. Iwo magumo echamupupuri ari pakati pamusoro pePasi uye cumulonimbus gore. Icho cyclonic yemuchadenga chiitiko chine huwandu hwesimba, kunyangwe vachiwanzo gara kwenguva pfupi.
Madutu anoumbwa anogona kuve nemhando dzakasiyana uye maumbirwo uye iyo nguva yavanogara yekupedzisira pakati pemasekondi mashoma uye inopfuura awa. Iyo inozivikanwa kwazvo tornado morphology ndeye faneli gore, ane magumo matete anobata pasi uye anowanzo kukomberedzwa negore riri kudhonzera guruva nemarara akakomberedza.
Nhanho inogona kusvika madutu ari pakati 65 uye 180 km / h uye inogona kuva 75 metres paupamhi. Tornadoes haigare yakamira kwavanogadzira, asi kuti famba uchiyambuka ndima. Vanowanzo famba kusvika kumakiromita akati wandei vasati vanyangarika.
Yakanyanya kunyanyisa inogona kuva nemhepo nekumhanyisa dzinogona kutenderera pa450 km / h kana kupfuura, kuyera kusvika 2 km yakafara uye ramba uchibata pasi kweanopfuura zana km.
Chamupupuri chakaita sei
Tornadoes dzinozvarwa kubva kune mabhanan'ana uye kazhinji dzinoperekedzwa nechimvuramabwe. Kuti chamupupuri chigadzire, mamiriro e shanduko munzira uye nekukurumidza kwedutu, kugadzira mhedzisiro inotenderera yakatwasuka. Kana izvi zvikaitika, koni yakatwasuka inogadzirwa kuburikidza nemhepo inomuka, ichitenderera mukati medutu.
Iyo meteorological phenomena inosimudzira kuoneka kwechamupupuri inowanzoita zvakanyanya mukati mehusiku kupfuura husiku (kunyanya panguva dzemadekwana) uye nguva ye gore rematsutso nematsutso. Izvi zvinoreva kuti chamupupuri chinonyanya kuumbika muchirimo nekudonha uye mukati mezuva, ndiko kuti, ivo vanowanzoitika panguva dzino. Nekudaro, chamupupuri chinogona kuitika chero nguva yezuva uye chero zuva regore.
Where is tornado alley inowanikwa
Matunhu akati wandei eUnited States anotarirwa nechamupupuri, kusanganisira Gulf Coast, Southern Plains, Upper Midwest, uye Northern Plains. Nekudaro, dzinenge nyika dzese dzakasangana nemadutu, kunyangwe madutu anowanzoitika pakati peAppalachian Mountains neRocky Mountains pakati peUnited States. Izwi rekuti "tornado corridor" rakagadzirwa naKaputeni Robert Miller naMajor Ernest Fabush, avo vakariisa muchirongwa chetsvakiridzo cha1952 ichidzidza mamiriro ekunze akaipa muOklahoma neTexas.
Kunyange zvazvo izwi iri richireva nzvimbo iri pakati peUS inowanzoitika madutu, National Weather Service haina kupa tsananguro yepamutemo yairi. Naizvozvo, nzvimbo dzakasiyana uye matunhu anogara achisanganisirwa muTornado Alley.
Kunyangwe miganhu yeTornado Alley ichisiyana nekwakabva, inovhara Great Plains nyika dzeLouisiana, Texas, Iowa, Kansas, South Dakota, Oklahoma, uye Nebraska. Mamwe masosi anosanganisira anoti Illinois, Wisconsin, Indiana, kumadokero kweOhio, uye Minnesota sechikamu cheTornado Alley. Tornado Alley inogonawo kutsanangurwa senzvimbo ine chamupupuri chakanyanya. Mamwe masosi anoratidzawo kuti kune akati wandei tornado alleys mukuwedzera kune iyo nzvimbo kubva kuTexas kuenda kuKansas. Aya alleys anogona kusanganisira Upper Midwest, Lower Mississippi, Tennessee, uye Ohio mipata.
Ndekupi Alley chamupupuri chinowanzoitika
Chamupupuri chakajairika muUnited States nekuda kwekudziya kwekunze. Tornadoes inogona kuumba chero munyika uye mhiri kweNorth America kondinendi, uye United States inosangana nemadutu makuru anosvika chiuru nemazana maviri gore rega rega. Zvakadaro, Tornado Alley ndiyo imwe yenzvimbo dzinonyanya kubatwa nechamupupuri nokuti mizhinji yemamiriro ezvinhu anodiwa kuti dutu riumbe anotekeshera munzvimbo iyi.
Chikamu cheGreat Plains, nzvimbo iyi yakati sandara uye yakaoma, zvichiita kuti ive nzvimbo yakanaka yekusangana kwevazhinji vemhepo. Mhepo inodziya inosimuka kubva kuGulf yeMexico inosangana nemhepo inotonhora, yakaoma kubva kuRocky Mountains. Kana aya mapoka emhepo anokwikwidza asangana, mhepo inotonhora, yakaoma inonyura uye inodziya, mhepo yakanyorova inokwira, kuunza dutu rine simba.
tornado frequency
Texas yakasangana nechamupupuri chakanyanya nekuda kwehukuru hwayo nenzvimbo iri kure kumaodzanyemba kwedunhu. Nekudaro, Kansas yakashuma nzvimbo dzakawanda dzechamupupuri muna 2007, ichiteverwa neOklahoma. Kunyangwe Florida yakataura kazhinji madutu muna 2013, madutu akanga asina kusimba semapani okumaodzanyemba. Florida yakaenzana nechamupupuri che12,2 pamakiromita zviuru gumi pagore pakati pa10.000 na1991, zvichiita kuti ive nyika ine chamupupuri chakanyanya padunhu panguva iyoyo, ichiteverwa neKansas (2010) neMaryland (11,7). Texas yakarekodha 9,9 chamupupuri pachikamu chenzvimbo pagore panguva imwe cheteyo.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve Alley chamupupuri uye maitiro ayo.
