Lub thiaj li hu ua kab xev tshwm sim nyob rau hauv lub ntuj ntawm khaus radiance. Lawv dai rau qhov tsaus ntuj nti ntuj zoo li ib tug lossis loj ntaub los yog drape rau qhov zoo nkauj toj roob hauv pes. Thaum lub hwj chim ntawm no tej yam ntuj tso phenomenon yog txo, ribbons muab rau hauv thaj ua rau thaj, thiab tej zaum kuj ploj zoo rau nws.

Lawv feem ntau yog ncab los ntawm sab hnub poob mus rau sab hnub tuaj ntawm ib qhov siab ntawm pua pua ntawm kilometers. Ib me ntsis thickness ntawm no amazing "ntaub" (ob peb puas meters) tso cai rau koj mus saib tau nrog cov liab qab qhov muag hnub qub los ntawm nws. Lub sab ntug ntawm tus aurora siv yuav ntshiab liab los yog liab Hawj txawm, thiab rau sab saum toj - maj dissolves nyob rau hauv lub qhov siab ntawm qhov tsaus ntuj nti ntuj, tsim ib tug superior nyhuv ntawm qhov tob thiab infinity ntawm lub ntug.

Auroras yog ob peb hom: radiant arc (daim kab xev, uas tej zaum yuav ua mob thaum mus txoj kev me me folds), homogeneous arc (luminous band muaj qhov nyuaj daim ntawv no, kaj, tab sis, nrog zog maj disappearing) thiab radiant sawb (tsim los ntawm high kev ua si thaum loj folds ntawm no tej yam ntuj tso phenomenon superimposed nyob rau me me thiab).

Muaj aurora, tsis muaj feem xyuam rau ib yam ntawm cov tsiaj. Nws ua si heev, vim nws yog generated los ntawm cov hnub ci zog. Qhov no glow yog zoo li tus zoo li kaus mom, whitish-ntsuab Hawj txawm, nws extends tshaj rau tag nrho cov ncov qaumteb qabteb cheeb tsam thiab hu ua squall.

Raws li cov brightness ntawm cov natural phenomena yuav tau muab faib ua plaub hom. Tom qab tag nrho, lawv ntxoov ntxoo txawv kaum lub sij hawm, tsim ib tug yeeb yuj aurora. Photo tim khawv rau qhov no, raws li lawv muaj peev xwm kom meej meej pom qhov txawv nyob rau hauv kev siv. Lub teeb los ntawm qhov tsaus muag glow NW nyuam qhuav hnov li cas, tab sis nyob rau hauv lub muaj zog heev - zoo li lub teeb ntawm lub hli. Cov txheej txheem hais nws tuaj txog ntawm ib tug ceev ntawm 1 km / sec. Yog li muaj ib tug cua kub kab mob nyob rau hauv huab cua, thiab nws directs upwards. Tej aurora induces eddy hluav taws xob currents uas ntes ib tug loj ib feem ntawm cov cua thiab tsim ntxiv tsis ruaj tsis khov magnetic teb, ua lub sib nqus los nag.

Homogeneous qauv yog rau no phenomenon lub ntsiab daim ntawv no, thiab tag nrho cov folds thiab loops - nws yog ib tug tshuaj tiv thaiv rau qhov kev nce rau hauv kev ua si, nrog rau ib qho kev nce rau hauv uas lawv loj rau ib tug enormous loj, me, thiab nrog ib tug txo - ploj zoo rau nws.

Zoo li cov radiance cuam tshuam rau ionosphere, hloov nws. Tej kev hloov tej zaum yuav ua rau ib tug phem hauv xov tooj cua puag ncig los yog mus rau nws qhaj ntawv.

Yog li, nws muaj kev ruaj ntseg los xaus hais tias cov aurora borealis - yog lub feem ntau zoo nkauj, zoo kawg li thiab nws tej yam ntuj tso phenomenon. Nws yog ib tug txuj ci tseem ceeb ntawm peb ntiaj chaw, uas tseem haum, surprises thiab yog ib tug ntau ntawm cov secrets thiab mysteries.
