Umhlaba wethu ugcwele izimfihlakalo nezimangaliso. Esinye sezimo ezinhle kakhulu futhi eziyimfihlakalo zomkhathi amalambu asenyakatho. Emehlweni abantu bakhe, imibala ehlukahlukene ehlangene nomunye, ubujamo obumangalisayo nemithunzi kuyamangaza. Isibhakabhaka esinemibala ehlukahlukene siholela esimweni sokushaqeka, sikuthathe ezweni elihluke ngokuphelele lezinganekwane, likwenze ukhuluphele izindinganiso zabantu.
Siyini lesi simangaliso semvelo?
Isikhathi eside, abantu abaphila emakhulwini eminyaka adlule babecabanga ukuthi ukukhanya kwezulu kuyisibonakaliso esibi, noma isibonakaliso sokuphela komhlaba okuseduze. Namuhla abantu bayayijabulela futhi bayayithanda le nto. Ngaphezu kwalokho, abantu ababone ukukhanya komkhathi babizwa ngenhlanhla.
Ngokombono wesayensi yobuhle obedlulele, into esemkhathini iyinkanyiso lapho kungabonwa khona inani elikhulu lama-flare nokuqhuma. Amandla ale nqubo awanakulinganiswa. Inkanyezi yethu iqukethe ama-microparticles of matter, nawo aphonswe emkhathini (lokhu kwenzeka ngamandla amakhulu). Ngaphezu kwalokho, lapho ukuqhamuka kunamandla kwenzeka, udaba oluningi luwela eplanethi yoMhlaba. Izinhlayiya ezihlukile ezikhokhiswa amandla ziyakwazi ukungena emkhathini wethu emahoreni ambalwa nje. Ngenxa yamandla kazibuthe womhlaba, izinto ezincane kakhulu ziyakhanga.
Ngenxa yesimo esingaziwa kalula ezingongolweni zomhlaba, kuvela i-aurora. Amandla we-solar flare nawo athinta ukukhanya nobude besimo. Ama-electron nama-proton akhangwa ezigxotsheni zomhlaba, ngenxa yalokho okuvela kuzo zonke izinhlobo zamaphethini, acwebezela ngemibala ehlukahlukene.
Ungazibona kuphi futhi nini izibani ze-polar?
Amathuba esimo esiyingqayizivele somkhathi ancike ngokuphelele ekusebenzeni kwelanga. Cishe akunakwenzeka ukubikezela izibani ezisenyakatho. Esikhathini esiningi, lesi simo singabonwa esikhathini esiphakathi kwekwindla nentwasahlobo, okungukuthi: kusuka ngoSepthemba 21 kuya kuMashi 21. Ngalesi sikhathi sesikhathi, ubusuku buqala kakhulu.
Kubalulekile ukuqonda ukuthi ukuqala kwamalambu asenyakatho kuncike esifundeni lapho kwenzeka khona isimo somkhathi. Kwamanye amazwe, "isibhakabhaka esimibalabala" singabonakala ngoDisemba, kwamanye - ngo-Ephreli. Kunconywa ukubheka i-aurora ngalesi sikhathi sokuphumula: kusuka ku-21.00 kuye ku-23.30. Isimo sezulu esicacile nesineqhwa - ekahle ekubukeni.
Ukubonakala okuhle kwe-aurora kubonwa ezindaweni ezingama-67-70 degrees, okuyilezi: ukusuka e-Alaska kuya enhlonhlweni yaseScandinavia. Kaningi, kwenzeka isimo somoya eScotland ngisho naseRussia (ingxenye emaphakathi).
Ukuzibona kuphi izibani ezisenyakatho eRussia
- IKhatanga, iKrasnoyarsk Territory
- Isifunda sase-Arkhangelsk, esifundeni sase-Arkhangelsk
- EMurmansk, esifundeni saseMurmansk
- IKhibiny, iKola Peninsula
- IVorkuta, Komi Republic
Amazwe "aphumelele kakhulu", okuvame ukwenzeka endaweni yawo ukukhanya okukhulu komoya ongaphezulu, yi: Finland, Norway, Iceland. Isibonelo, esifundeni saseKilpisjärvi, lo mkhuba uvela ezimweni ezintathu kwezine. Kwezinye izifunda, "amadolobha ezinkanyezi" akhethekile adaliwe, lapho ungahlala khona kamnandi ubabaze isimangaliso semvelo.
ILapland iheha izivakashi eziningi zaseNorway. Kule ndawo kunendawo yokubuka enendawo yokubuka. Idolobha lase-Alta linemikhosi ye-aurora.
Amaqiniso athakazelisayo ngamalambu asenyakatho
Kungcono ukubuka amalambu we-polar kude nedolobha. Ukukhanyisa kuphazamisa ukubonakala futhi akuvumeli ukudlulisa yonke imibala nemithunzi yesimo somkhathi. Amathuba okubona i-aurora akhula phakathi kwamabili. Uma kubanda futhi kucace ngaphandle, kulapho kuzobonakala kangcono lo mkhuba.
Njalo ngonyaka inani lezivakashi ezifuna ukubona amalambu asenyakatho lenyuka kaningana. Okuwukuphela kwento ebuyayo ukungalindelekile nokungafinyeleleki kwalesi senzakalo.
