Ngokuqinisekileyo ayikho iNgqungquthela.
Ikhefu laseArizona lizisa ieholide, iindlovu , kunye nama-microbursts ngezihlandlo. Ngenye ihlobo iimeko zemozulu zenzeke kwiimeko eziyingozi kunye nomonakalo.
Yintoni i-Microburst?
I-downburst ichazwa njenge-downdraft eqinile kunye nokuphuma kweemimoya ezonakalisayo okanye kufuphi nomhlaba. Ukuba i-swath ingaphantsi kweekhilomitha ezingama-2.5, ibizwa ngokuba yi-microburst.
I-microburst yinto encinci, enamandla kakhulu ehla ehlabathini eya kubakho umoya ogqithiseleyo.
Ubukhulu bomcimbi buqheleke ngaphantsi kweekhilomitha ezili-4 ngaphesheya. I-Microbursts iyakwazi ukuvelisa imimoya engaphezu kwe-100 mph ebangela umonakalo omkhulu. Ubomi be-microburst buphakathi kwemizuzu emi-5 ukuya kwe-15. Kukho i-microbursts emanzi kunye ne-microbursts eyomileyo.
Xa imvula iwela phantsi kwesiseko sefu okanye ixutywe nomoya omile, iqala ukuphazamiseka kwaye le nkqubo yokukhuphuka iphosa umoya. Umoya opholileyo uhla kwaye ukhawuleze njengoko ufikelela emhlabathini. Xa umoya opholileyo usondela kumhlaba, usasazeka kuzo zonke izikhokelo kwaye ukuhlukana komoya kukusayinwa kwe-microburst. Kwiindawo ezinomdaka, i-microbursts inokuvelisa kwiindwangu ezinkulu.
I-Microbursts ikhawuleza ukubetha iziganeko kwaye iyingozi kakhulu kwi-aircraft. I-microbursts ihlelwa phantsi njengendawo emile okanye emanzi, ngokuxhomekeke kwimvula enkulu ehamba ne-microburst xa ifikelele emhlabathini. Ukuba i-swath ingaphezu kweekhilomitha ezingama-2.5, ibizwa ngokuba yi-macroburst.
I-Macroburst ihlala ixesha elide ngaphezu kwe-microbursts.
Ngaba i-Microburst iTornado?
Hayi, kodwa kukho ukufana okufanayo. Kukho ixesha elininzi umoya onokukhula ngokukhawuleza. Ukwahluke kunokuba i-microburst, nangona kunjalo, umoya ugeleza kwiqhankqalazi kwaye ungaphumi, njengokuba wenza kwi-downburst. I-Tornados nayo ibangela ukuba umoya ojikelezayo owubona kwiinkomfa ezininzi kunye nevidiyo, ezingenakwenzeka ngexesha le-microburst.
I-microbursts zixhaphake kakhulu kuneziqhwithi, kwaye akunqabile ukuba neqhwithi endaweni yasePenix ngethuba lehlobo lasehlobo .
Ngaba i-Microbursts Yenza Imonakalo?
Ewe, banako. Umonakalo we-Tornado udla ngokubonakalayo, kunye nemithi emikhulu ehluthwe ngokukhawuleza iwela ngaphaya, ngelixa ukulimala kwe-microburst kudla ukuwashiya ekwahlulelweni olufanayo okanye ephawulwe.
