Kungani ebusika awekho izikhala ezidumazayo?

Abantu babehlale benaka kakhulu ukuduma kwezulu. Babehlotshaniswa nemifanekiso eminingi emangqamuzana, ukuqagela kwenziwa ngezindlela ezibukeka ngayo. Isayensi iye yaqonda lokhu maduzane - ngekhulu le-XVIII. Abantu abaningi basalokhu behlushwa umbuzo: kungani kungekho khona ukuduma kwezulu ebusika? Ngaphezu kwalokho kulesi sihloko, sizobhekana nalokhu.

Isiphepho sithini?

I-physics evamile isebenza lapha. Isivunguvungu siyisimangaliso esimweni somkhathi. Kusukela emvula ejwayelekile kuyahluka ukuthi lapho kunoma yikuphi ukuduma kwezulu kukhona ukukhishwa kagesi okuqinile okuhlanganisa ama-cumulus amafu emvula noma komunye nomhlaba noma ngomhlaba. Lezi zigaba nazo zihambisana nemisindo enkulu yokuduma. Ngokuvamile umoya uyanda, ngezinye izikhathi ufinyelele isiphepho siphepho-siphepho, kukhona isichotho. Ngokushesha ngaphambi kokuqala, umoya, njengombuso, uba yinto egcwele futhi idonsa, ifinyelela izinga lokushisa eliphezulu.

Izinhlobo zeziphepho

Kunezinhlobo ezimbili eziyinhloko zokuduma kwezulu:

• I-Intramuscular;

• Ngaphambili.

I-Intratrass ukuduma kwezulu kubangelwa ukushisa okukhulu kwemoya futhi, ngokufanayo, ukushayisana komoya oshisayo eduze komhlaba nomoya obandayo phezulu. Ngenxa yalesi sici, ziboshwe ngokuqinile ngesikhathi futhi, njengomthetho, ziqala ntambama. Ngolwandle, bangadlula ebusuku, ngenkathi behamba phezu kwamanzi okushisa.

Ukuduma kwemvula kwangaphambili kwenzeka uma izingxenye ezimbili zomoya zithinta - zifudumele futhi zibandayo. Akuxhomeki esikhathini sosuku.

Ukuvama kwemvula yokuduma kuncike ekushiseni okujwayelekile esifundeni lapho kwenzeka khona. Ehlisa izinga lokushisa, cishe ngeke kwenzeke. Ezingxenyeni, zingasetshenziswa kanye kuphela eminyakeni embalwa, futhi ziphela ngokushesha. I-Indonesia, isibonelo, idume ngezikhathi eziningi zokuduma kwezulu, okungaqala izikhathi ezingaphezu kwamakhulu amabili ngonyaka. Kodwa-ke, zidlulela eziqhingini nezinye izindawo lapho imvula engeke ivele khona.

Kungani ukuduma kwemvula kwenzeka?

Isizathu esiyinhloko semvelaphi yokuduma kwemvula kungukushisa okungalingani kwemoya. Ukuphakama kwezinga lokushisa emkhatsini womhlabathi kanye nokuphakama, okunamandla futhi kaningi ukuduma kwezulu kuzokwenzeka. Umbuzo uhlala uvulekile: kungani kungekho ukuduma kwemvula ebusika?

Indlela yokwenza lokhu kwenzeka lokhu okulandelayo: umoya oshisayo ovela emhlabathini, ngokusho komthetho wokushisa ukufudumala, uhamba phezulu, kanti umoya obandayo ovela engxenyeni engenhla yefu, kanye neqhwa elikuwo, ugoba phansi. Njengomphumela walo mjikelezo, ezingxenyeni zefu ezisekela amazinga okushisa ahlukene, kunezindleko zamandla kagesi ahlukene: ama-particles amisiwe aqoqwe phansi, futhi amabi - phezulu.

Ngaso sonke isikhathi lapho behamba phakathi kwezingxenye ezimbili zefu, inhlansi enkulu iqhuma, eqinisweni, yombani. Umsindo wokuqhuma okwenziwe yi-spark umoya oshisayo, futhi kukhona ukuduma okudumile. Ijubane lokukhanya liphakeme kunejubane lomsindo, ngakho ukukhanya nokuduma akusifinyeleli kanyekanye.

Izinhlobo zombane

Wonke umuntu ubonile ukukhanya kwe-lightning-spark evamile kaningi kanye futhi ngokuqinisekile wezwa nge- lightning ibhola. Noma kunjalo, lokhu akuwona kuphela ukukhanya kwamandla okubangelwa ukuduma kwezulu.

Kunezinhlobo ezine eziyinhloko eziyinhloko:

1. Ukukhanyisa izibani, ukushaya phakathi kwamafu nokungathinti umhlabathi.
2. Itheyipu, ukuxhuma amafu nomhlaba, yiwona umbani onobungozi kunazo zonke, okumele ukwesatshwe kakhulu.
3. Umbani ovuthayo osika isibhakabhaka ngaphansi kwezinga lamafu. Babhekwa njengengozi kakhulu kubahlali basezingeni eliphezulu, ngoba bangakwazi ukwehlisa phansi ngokwanele, kodwa bangathinti phansi.
4. Ama-Fireballs.

Kungani kungabikho ukuduma kwemvula ebusika ebanda?

Impendulo yalo mbuzo ilula. Kungani kungabikho ukuduma kwezulu ebusika? Ngenxa yamazinga okushisa aphansi eduze komhlaba. Ayikho umehluko ocacile phakathi kwemoya efudumele evuthayo ngezansi, nomoya obandayo ovela ezingxenyeni ezingaphezulu zomkhathi, ngakho-ke icala lokugesi elisefwini lihlale libi. Yingakho kungekho ukuduma kwemvula ebusika.

Yiqiniso, lokhu kusho ukuthi emazweni ashisayo lapho izinga lokubanda ebusika lihlala lihle, liqhubeka lwenzeka kungakhathaliseki ukuthi liyisizini. Ngakho-ke, ezindaweni ezibandayo zezwe, ngokwesibonelo e-Arctic noma e-Antarctica, isivunguvungu siyisimo esikhulu kunazo zonke, kufana nemvula ehlane.

Izivunguvungu zomsakazo zivame ukuqala, ekupheleni kukaMashi noma ngo-Ephreli, lapho iqhwa elicishe libe khona. Ukubukeka kwaso kusho ukuthi umhlaba uvuselele ngokwanele ukunikeza ukushisa futhi ulungele izitshalo. Ngakho-ke, lapho kukhona ukuduma kwezulu kwentwasahlobo, izimpawu zabantu abaningi zihlobene.

Ukuqala kwezulu kwentwasahlobo kungadala emhlabeni: njengomthetho, kwenzeka ngesikhathi sokushisa okungavamile, lapho isimo sesimo sezulu singakabi khona, futhi siletha umswakama ongadingekile. Ngemuva kwalokhu, umhlabathi uvame ukucwilisa, ubanda futhi unikeze isivuno esibi.

Ukuqapha ngesikhathi sokuduma kwezulu

Ukuze ugweme umbane, ungayeki eduze nezinto eziphakeme, ikakhulukazi abangashadile - izihlahla, amapayipi nezinye. Uma kunokwenzeka, kungcono ukuthi kungabi ngaphezu kwentaba.

Amanzi ngumqhubi omkhulu kagesi, ngakho-ke umthetho wokuqala kulabo abaphethwe yisiphepho ngeke kube semanzini. Phela, uma umbani uhlasela ubhedu ngisho nangesikhathi eside, ukukhishwa kuyofinyelela kalula umuntu omi kulo. Okufanayo kusebenza ezweni elimanzi, ngakho-ke ukuxhumana nabo kufanele kube mncane, nezingubo kanye nomzimba - uma kungenzeka kunomile.

Ungathintani nemishini yasendlini noma amaselula.

Uma ukuduma kwemvula kubanjwe emotweni - kungcono ukuthi ungashiyi, amathayi enjoloba ahlinzeka kahle.
