Halo yelanga

Ngamaxesha amaninzi, oososayensi baye babanzima kakhulu ekuchazeni ezinye zeemeko zemozulu ezenzeka kwiplanethi yethu. Nokuba kungokuhamba kwayo okungaqhelekanga okanye ngenxa yokusebenza kwayo. Kule meko siza kuthetha ngesenzeko esasicotha ukuba imvelaphi yaso ichazwe ziifiziksi zemozulu. Imalunga ne-halo yelanga.

Isangqa selanga sisangqa esikhanyayo esidla ngokwenza iifom ejikeleze iLanga kwaye sinokubonwa emhlabeni. Kodwa yenziwa njani kwaye kweziphi iimeko? Ukuba ufuna ukwazi ngakumbi, qhubeka ufunda.

Yenziwa njani i-halo yelanga?

Le nto ibandakanya isangqa eliqaqambileyo ngeenxa zonke ilanga yaziwa ngokuba yi-halo okanye i-antelia. Oku kwenzeka ikakhulu kwiindawo ezibandayo njengeRussia, Antarctica, okanye emantla eScandinavia. Nangona kunjalo, okoko nje iimeko ezifanelekileyo zibakhona ekwakhiweni kwayo, zinokwenzeka kwezinye iindawo.

Le halo yenziwa ngamasuntswana omkhenkce abekwe kwindawo ephezulu yetroposphere. Xa ilanga liwela kula maqhekeza womkhenkce, ukukhanya kwakhona ukwenza yonke imibala ebonakalayo (efana nale yomnyama) ibonakale ijikeleze iLanga. Singayibiza ngokuba ngumnyama oyisetyhula obonakala ikakhulu ngokuba menyezelayo.

Ukuze le meko yenzeke kwiindawo apho amaqondo obushushu aqhele ukuba sezantsi, kufuneka kubekho umahluko omkhulu phakathi kobushushu bomphezulu nobude. Ukuze i-halo yelanga yenze, Kufuneka kubekho iikristali zomkhenkce ezaneleyo kwindawo ephezulu Unokubuyisela ukukhanya okwaneleyo ukwenza i-halo epheleleyo. Kwiindawo apho amaqondo obushushu ephezulu, le meko ayinakubonwa.

Umahluko wobushushu obuphezulu uvame ukwenzeka ngentseni, apho umoya ubanda ngakumbi njengoko ubungenawo umthombo wobushushu belanga ubusuku bonke. Ke ngoko, le halo ihlala ibonwa ngentsasa.

Kuyimfuneko ukuba Uhlobo lwamafu okwangoku esibhakabhakeni ngamafu e-cirrus. La mafu enziwe ngekristali ezincinci zomkhenkce ezinokufumana ukubonakaliswa kunye nokukhanya kokukhanya okuvela eLangeni.

Ephakamileyo kwi-troposphere, ukukhanya kwelanga kubetha i-crystals ye-ice kunye neziqhekeza njengoko zidlula. Umoya oshushu ophuma emhlabeni ubangela ukufuma kunyuke, kubangele ukwakheka kwamafu. Xa amafu efikelela kweyona ndawo iphezulu yetroposphere, uguqula oko kufuma kube ziikristale zamanzi okuthi, xa zifumana ilanga elithe ngqo, zikubole ukuze zenze isangqa selanga.

Izixhobo

I-Solos halos iqhele ukuba nayo i-engile emalunga nama-22 degrees. Xa i-halo yelanga isenzeka, ukuba umntu wakhomba ngesandla sakhe sijonge eLangeni, ayinamsebenzi ukuba ukhomba phi, i-halo iyakwenza i-angle ye-22 degrees.

Umphetho wayo wangaphakathi uhlala unombala ungqombela kwimbonakalo kwaye eyona milo iqhelekileyo yile yesangqa sokukhanya esikumda weLanga. Ngamanye amaxesha ungabona enye ihalo ebangelwe ziikristale zomkhenkce ezimiswe ujikeleze ilanga. I-halo ephambili ene-engile yeedigri ezingama-46 ukusuka embindini weLanga. Kukho nezinye iintlobo zokukhanya okufana ne-halo yelanga. Ezi zezinto zibizwa ngokuba lilanga lobuxoki okanye iiparahelios kwaye zinokubonwa kwiidigri ezingama-22 ngokubhekisele elangeni, ngokuthe nkqo nangokuthe tye. La malanga obuxoki yimifanekiso ekhanyayo emile ngokufana nediski yelanga.

Ukudideka xa ubona i-halo yelanga

Ngamanye amaxesha i-halo yelanga inokudideka nezithsaba ezenzeka ngeentsuku apho imozulu inkungu. Izithsaba ezinokubonwa xa amafu amdaka egubungele isibhakabhaka aveliswa ngokusasazeka kokukhanya xa ugqitha kumasuntswana amiswe emoyeni. Ezi zithsaba zinokufana, kwimeko yeemeko zokwakheka kwemvula, kunye nemingxunya yokukhanya okumhlophe okanye tyheli. Ezi arcs zefom yokukhanya emhlophe xa kukho inkungu. Ukukhanya kwelanga kubetha kwibhanki yenkungu kwaye ukukhanya okuqaqambileyo kwenzeka kwi-engile yeedigri ezingama-40 ukusuka embindini welanga.

Unokuboniswa njani?

Eyona halo ixhaphakileyo yenziwa ziinkqubo zokuphinda zikhuphe umkhenkce omile okweempondo. Le meko ikumkhenkce yenza ukuba ukubanakho ukuphinda ubonakalise imibala engaphezulu yesilinganiselo.

Njengoko kukhankanyiwe kwamanye amanqaku afana neli Umaleko womoyaNjengoko sonyusa ukuphakama kwi-troposphere, amaqondo obushushu ayancipha. Ngale ndlela, kwelona nqanaba liphezulu le-troposphere, amaqondo obushushu asezantsi. Kakhulu, kangangokuba phantse i-10 km, iqondo lobushushu elikuyo -60 degrees. Kula maqondo obushushu asezantsi kakhulu, amathontsi amanzi amisiweyo ziikristale ezinokukhupha ukukhanya kwelanga kwaye zenze i-halo.

Ukuyibona ngokuchanekileyo i-halo yelanga kwaye uyonwabele le nto ingaqhelekanga, Kuya kufuneka ibonwe ukuthintela ukujonga ngqo kwiLanga. Siyakhumbula ukuba ukujonga iLanga ngokuthe ngqo kunokubangela umonakalo omkhulu kwi-cornea kunye nokulahleka kombono ngenxa yemali enkulu yelanga kunye nemitha ye-UV eyonakalisa izicubu zamehlo. Eyona nto intle ukuyenza ukubona olu hlobo lwe-halo kukusebenzisa into ejikelezayo esinceda ukugubungela iLanga kwaye sikwazi ukonwabela umbono wale halo. Iiglasi ezisetyenziselwa ukubona ukutshona kwelanga zinokusetyenziswa.

Njengoko ubona, izinto ezininzi zemozulu zenzeka kwiplanethi yethu, kude kube kudala, isizathu sokwakheka kwabo besingaziwa. Nangona kunjalo, enkosi kukufumanisa okwenziwe luluntu lwenzululwazi, namhlanje singonwabela imo yezulu ezinje ngesangqa selanga, sisazi imvelaphi kunye neempawu zokwakheka.

Kwaye wena, wakhe wayibona i-halo yelanga?
