Ngamathub’ athile, sibona into ebizwa ngokuba yi<em>halo ejikeleze inyanga okanye ilanga, edla ngokubonisa idisk eqaqambileyo ejikeleze isangqa sangaphandle senkwenkwezi nganye. Ngokuqhelekileyo, le nto ixhaphake kwiindawo ezibandayo zehlabathi, njenge-Antarctica, iGreenland, iAlaska kunye neSiberia, kodwa inokubonwa nakwezinye iindawo ezinemozulu efanelekileyo. I inyanga halo Inokuza ukubonisa iimeko ezithile.
Kule nqaku siza kukuxelela yonke into okufuneka uyazi malunga ne-halo yenyanga, iimpawu zayo, imvelaphi kunye nentsingiselo yayo.
Yintoni ihalo yenyanga
Kwiimeko zomoya ophakathi apho Lo mcimbi unokubonwa kwimimandla epholileyo, amafu akhanyayo abonakaliswa yingqele, ebizwa ngokuba ngamafu e<em>cirrus, anokuveliswa. Esi siganeko se-atmospheric senzeka xa amasuntswana omkhenkce amancinci exhonywe emoyeni ngokuthe ngqo kwi-troposphere, kwaye la masuntswana aphinda aqhawuke xa efumana ukukhanya kwelanga, enze i-spectrum ejikeleze inyanga okanye ilanga.
Olunye lweempawu zokubunjwa kweringi esinokuthi siziqaqambise kukuba i-iridescent, idala isiphumo ngokungathi ino "ukukhanya" kwayo, okubandakanya obomvu (ngaphakathi kweringi) kunye ne-black ngaphandle kweringi. Oku. Nangona kunjalo, ngamanye amaxesha kubonakala ngathi umnyama wonke uyabumba.
Umbala oqhelekileyo ubonakala umhlophe, ngamanye amaxesha ufikelela kwi-hue ephaphathekileyo ngokupheleleyo ngenxa yokukhanya okusemva okuveliswa ngumbala wesibhakabhaka. Iziganeko ezibonakalayo ezenza oku kwenzeke zizinto ezibonisayo kunye nokuchaswa kweekristale zomkhenkce.
Ezi zikholisa ukubumba kweyona mafu aphakamileyo anokuthi enze kwiatmosfera, ebizwa ngokuba nguKoreshi, Banokufikelela kubude beemitha ezingama-20.000. Ukubuyela kumcimbi we-halos, enye yeehalos eziqhelekileyo eziqhelekileyo ziveliswa yi-halo eyenziwe yinkqubo ye-refractive, ebangela ukuba ukukhanya kudlule kwi-crystals ene-hexagonal.
Iintlobo zehalo yenyanga
Esi siganeko sikholisa ukwenzeka kwitroposphere, owona maleko uphantsi weatmosfera nalapho uninzi lwezehlo zemozulu eMhlabeni zenzeka. Ngokungathi oko akwanelanga, uninzi lweentlobo ezahlukeneyo zamaleko zamafu akhoyo adla ngokubumba kwaye aqokelelane kolu maleko.
Kwiminyaka yakutshanje, lo maleko womhlaba we-atmosfera uye wafumana utshintsho oluthile, ubanda kakhulu kuninzi lwawo (iikhilomitha ezili-10 ukuphakama), ukufikelela -65º kwiindawo ezininzi. Ngenxa yoko, amasuntswana othuli kunye neekristale zeqhwa zivame ukuqokelela kulo maleko, isithako esibalulekileyo ekubunjweni kwezi ntlobo zamafu.
Kwimeko ye-halo, iringi yenziwa xa ukukhanya kwenyanga kukwazi ukujikisa ngeekristale ezincinci zomkhenkce. Nangona kunjalo, ukuba siqhathanisa ne-halos yelanga, kukho umehluko obalulekileyo, kuba olu hlobo lwe-halo lubonakala kuphela xa amafu aphezulu ngokwaneleyo (kufuphi nesathelayithi).
Ukuba zonke ezi mpawu bezikhona, ikristale yomkhenkce eqhelekileyo enamacala amathandathu inokubumba, ijike ukukhanya kwenyanga kwi-engile ethambekileyo ye-22°, ngaloo ndlela yenza i-ring epheleleyo kunye nobubanzi be-44 °.
Olunye uphawu ekufuneka lunyanzeliswe ukuze ukwazi ukujonga le nto kukuba inyanga kufuneka ibe kwisigaba senyanga epheleleyo, kuba kunzima ukujonga ihalo xa isathelayithi ikwezinye izigaba.
Imvelaphi kunye nokwakheka
Kuyaziwa ukuba nayiphi na i-iris halo, i-halo, okanye i-ring yi-optical effect evelisa idisk okanye i-ring ejikeleze inyanga (okanye ilanga) enombhalo oqaqambileyo kwicala elingaphandle lediski yokubonisa, okt. ithoni yokukhanya. Itshintsha ngokuxhomekeke kwi-angle yokujonga, le mpembelelo ifana noko kubonakala kwiiCD, iiDVD ezisetyenziswa ngokubanzi namhlanje.
Isiphumo esicacileyo se-iridescent sibangelwa iindawo ezininzi eziguquguqukayo apho utshintsho lwesigaba kunye nokuphazamiseka kokukhanyela ukukhanya kubonwa, ukwandisa okanye ukunciphisa ubude be-waveleng ngokuxhomekeke kwi-engile kunye nomgama wombukeli ngamnye ukusuka kwinto.
Ukukhanya okuqikelelweyo kwesi siphumo somnyama kumodulated okanye kuthweswe izidanga ngendlela enye okanye enye ngenxa yokuphazamiseka okwenzekayo xa ukukhanya kudlula, kwakhona kuxhomekeke kwi-engile yokujonga, imibala eyahlukileyo iya kuqikelelwa kwizinga eliphezulu okanye elisezantsi, livelisa umphumo ochazwe. Banjalo, njengoko sele kukhankanyiwe, inkqubo efana nenkangeleko yomnyama.
Iindawo ezilungileyo zokujonga i-halo yenyanga yiAlaska, iAtlantis, iGreenland nomntla weScandinavia, kwakunye nemimandla esemantla eRashiya neKhanada. (kufuphi neNorth Pole). Nangona kunjalo, ukuthetha ngokwesayensi, le nto inokubonwa naphi na, ukuba nje iimeko ezihambelanayo zomoya zikhona. Nalapho kukho izaqhwithi.
Amasuntswana omkhenkce emafini, kummandla we-troposphere, xa emisiwe adala uluhlu lwemibala ejikeleze iNyanga okanye iLanga ngokuxhomekeke kwimeko. Ngokuqhelekileyo, iithoni ezibomvu zibonwa kwindawo yangaphakathi yeringi kunye nohlaza okanye bluish kwindawo engaphandle. Ngandlel’ ithile, unokufana nomnyama ogcweleyo, oko kukuthi, ungqukuva.
Iihalo zenyanga eziqhelekileyo zityheli kwaye, kwezinye iimeko, zimhlophe. Yakhiwa ukusuka kwimimandla esemhlabeni, okanye kwezinye iiplanethi ezineatmosphere. Impembelelo ye-optical kukubonakalisa kunye nokuguqulwa kokukhanya, ngokusebenzisa iikristale ezincinci esele zibonisiwe, ezenza amafu aphakamileyo aphezulu ohlobo lwe-cirrus (oko kukuthi, loo mafu aphakamileyo aneekristale ezincinci).
Iimeko zehalo yenyanga ukuba yenzeke
Nokuba yeyiphi na imeko, ihalo imele into enqabileyo ekhanyayo kuba iimeko ezininzi kufuneka zihlangatyezwe, ezinje ngokuba kufuneka kubekho umoya obandayo kunye ne-iridescent, kunye neekristale ezaneleyo zokuphambukisa ukukhanya.
Ubukhulu bokukhanya kwenyanga, kuxhomekeka kwindawo ekuyo, buyanda okanye buyancipha, nto leyo echaza isizathu sokuba umntu ngamnye abone umfanekiso owahlukileyo kwindawo akuyo, umntu ngamnye. Ukuphambuka kokukhanya xa kudlula okanye kubetha iglasi skwaye ubonakalise kwiindlela ezininzi, kwaye ingqokelela yazo zonke ezi zitenxo zenza isangqa esiqikelelweyo.
Amaqondo okushisa aphantsi afunekayo ukwenza i-halo ngokufanelekileyo ichaphazela imozulu kwinqanaba elithile, ngoko kuchazwa ukuba i-halo ibonisa utshintsho kwindalo. Ngakolunye uhlangothi, iinkcukacha ezifanayo zomkhuhlane oqhelekileyo zingabonisa imiphumo ethile kwimpilo yabanye abantu, ukukwazi ukuvelisa izifo zokuphefumula okanye ezifanayo.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-halo yenyanga kunye neempawu zayo.
