Ngempela Akuyona Isiqhingi.
Isimo sezulu sase-Arizona siletha ukuduma kwehlobo ehlobo, izivunguvungu zothuli , kanye nama-microbursts ngezikhathi ezithile. Ngehlobo ngalinye lezi zindlela zezulu ziholela ezimweni eziyingozi nokulimala.
Iyini i-Microburst?
I-downburst ichazwa ngokuthi i-downdraft eqinile ngokuphuma kwemimoya ewonayo noma eduze nomhlabathi. Uma i-swath ingaphansi kwama-2.5 miles, ibizwa ngokuthi i-microburst.
I-microburst i-downdraft encane, enamandla kakhulu ehla emhlabathini eholela ekuhlukeni okukhulu komoya.
Ubukhulu bomcimbi ngokuvamile buphansi kwamakhilomitha angu-4 ngaphesheya. Ama-microbursts akwazi ukukhiqiza imimoya engaphezu kwe-100 mph ebangela umonakalo omkhulu. Ukuphila kwe-microburst kuphakathi kwemizuzu engu-5-15. Kukhona ama-microbursts anamanzi nama-microbursts owomile.
Uma imvula iwela ngaphansi kwesisekelo sefu noma ixubene nomoya omile, iqala ukuqhuma futhi inqubo yokukhuphuka iyaphazamisa umoya. Umoya opholile wehla futhi usheshisa njengoba usondela emhlabathini. Lapho umoya opholile ufika emhlabathini, usakazeka kuzo zonke izikhombisi-ndlela futhi lokhu kuhlukana komoya kuyisignesha ye-microburst. Ezimweni ezinomswakama, ama-microbursts nawo angabangela ukusalela okukhulu.
I-Microbursts iyimicimbi esheshayo yokushaya futhi iyingozi kakhulu ezindizeni. I-microbursts ihlukaniswa kancane njenge-microbursts eyomile noma emanzi, kuye ngokuthi imvula ihamba kanjani ne-microburst uma ifinyelela emhlabathini. Uma i-swath ingaphezu kwama-2.5 miles, ibizwa ngokuthi i-macroburst.
Ama-macrobursts ahlala isikhathi eside kunama-microbursts.
Ingabe i-Microburst i-Tornado?
Cha, kodwa kukhona ukufana okufanayo. Kuningi umoya ovame ukwanda ngokushesha. Nokho, okungafani ne-microburst, umoya ugeleza ungena enkantwini hhayi ngaphandle, njengokwenza ku-downburst. I-Tornados nayo iholela kulowo moya oshayayo owubona kuma-movie amaningi namavidiyo amaningi, okwamanje engekho ngesikhathi se-microburst.
Ama-microbursts ajwayelekile kakhulu kunezinkanyamba, futhi akuvamile ukuba nesiphepho endaweni yasePenieni ngisho nangesikhathi sasehlobo sasehlobo .
Ingabe i-Microbursts Yenza Ukulimala?
Yebo, ngokuqinisekile bayakwazi. Ukulimala kwe-Tornado kuvame ukubukeka okwenyukayo, izihlahla ezikhudlwana ezivuthiwe ngokuvamile ziwela, kanti ukulimala kwe-microburst kuvame ukuzishiya zibekwe eceleni noma zifakwe phansi.
