Izikhathi eziningi isibhakabhaka sisimangaza ngemibono emangalisayo. Ezikhathini eziningi siye sayeka ukucabanga ngokushona kwelanga okumangalisayo ngenxa yombala wesibhakabhaka. Kunesimo sezulu esaziwa ngokuthi ukukhanya kwezinyawo ebizwa nangokuthi i-flushed futhi eyaziwa kakhulu ngokuheha. Isibhakabhaka esivuthayo, esinemibala enemibala ebomvu, ewolintshi, ebomvana futhi ensomi. Ababoshiwe bamazulu banelukuluku lokufuna ukwazi ngoba kwesinye isikhathi ungaya kobheka kodwa ubathole.
Kulesi sihloko sizokutshela konke okudingeka ukwazi nge-candilazo, kungani ibizwa kanjalo nokuthi yiziphi izici zayo.
Siyini isibani
Ngokuphambene nalokho okukuthathile isiko le-pop, akuwona amafu amnyama "eza," kodwa iphalethi yokukhanya kwelanga ngokugcwele. Kodwa ... kungani ungababoni emini? Yiziphi izici ezizokwenza lo mkhuba ugqame? Ake sibheke izici ezithonya kakhulu ukukhula nobukhulu balo: ukuhlakazeka kokukhanya kwelanga kanye ne-angle yalo yokwenzeka emhlabeni, izinhlobo zamafu esibhakabhakeni kanye nenani lezinhlayiya noma umswakama osemkhathini.
Ukukhanya kwelanga kwenziwa ngayo yonke imibala eyingxenye "ye-spectrum ebonakalayo," futhi imibala esiyibona othinini iyisibonelo esihle. Kanjalo, yonke lemibala ihlakazeke kakhulu noma kancane kakhulu, okuncike ngokuyinhloko engeli yesigameko semisebe yelanga emkhathini wethu, njengoba kuboniswe ngezansi:
- Nini imisebe yelanga incike emkhathini, lapho ilanga liphakeme kakhulu emkhathizwe (i-solar zenith emini), amandla amakhulu kanye nokukhanya okuluhlaza okwesibhakabhaka okufushane (ngaphansi kuka-500 nm) kuzosakazeka emkhathini. Umkhathi uphumelela kakhulu, ukhukhula isibhakabhaka (oluhlaza okwesibhakabhaka) namafu (amhlophe noma ampunga) ngalowo mbala.
- Lapho imisebe yelanga ikhomba emkhathini ngendlela "ehambisana kakhulu", okwenzeka kuhwalala noma ekuseni, ukukhanya okuluhlaza kuzohlakazeka kamuva futhi kulahleke endleleni. Kulesi simo, ukukhanya okubomvu kuzoba yinde. Kubusa ubude begagasi (> 600 nm), khanyisa amafu "kusuka ngaphansi".
Amafu
Ngaphandle kwamafu bekungeke kube nethoshi, njengoba singabona intuitively ekupheleni kwesigaba esandulele. Sidinga ukhanvasi esizoveza kuwo ukukhanya okubomvu ukuze sikwazi ukubona ukukhanya okuvela esibhakabhakeni. Ngokujwayelekile kwi-meteorology sikhuluma ngezinhlobo ezahlukene zamafu ngokusho kobude bawo esibhakabhakeni: aphansi, aphakathi nendawo naphezulu.
Nokho, ukwazi lesi simo, sincike ukuba khona ezimbili zokugcina: medium (isisekelo esikhulu kunamamitha 2000) futhi high (isisekelo esikhulu kunamamitha 5000 noma 6000). Kulokhu, amafu aphansi ngeke asisize ngoba ayoyivimba kancane noma ayivimbe ngokuphelele imisebe yelanga. Kudingeka sivumele ukukhanya kudlule emafwini angaphansi kwawo futhi kukhanye kusukela phansi kwawo. Ngezinye izikhathi ngisho nokuphakama kwefu elikhulu le-cumulonimbus kuyakhanya.
Kumele kuqashelwe ukuthi amanye ama-nuances alesi simo angashintsha izimo zokubonisa zalesi simo:
- Umswakama ophezulu ubamba ingxenye yemisebe yelanga, obushelelezi. Lokhu kuvame ukwenzeka uma usebenzisa ithoshi ngemva kokuna, ikakhulukazi ngesikhathi sezimvula.
- Izinhlayiya ezingcolisayo zizokwenza "ukuvutha" kushube kakhulu. Ngemuva kwemisebenzi ye-anthropological engcolisa kakhulu, izinto ezivame ukwenzeka kakhulu ntambama.
Ingabe kungabikezelwa?
Kumelwe ukuba ulahleke izikhathi ezingaphezu kwesisodwa, ubukele ukushona kwelanga okuphuphile noma ukuphuma kwelanga kuthwetshuliwe, wonke la mafu akhanyiswa okubomvu okushubile kanye newolintshi, akunjalo? Ikhamera ingashintsha noma yisiphi isithombe se-landscape sibe umsebenzi wangempela wobuciko.
Kodwa, umangale kangaki i-flash emotweni, ekhaya noma emsebenzini? Impela izikhathi eziningi. Kukangaki uphuma nethimba lakho niyothwebula ukuphuma kwelanga noma ukushona kwelanga endaweni enhle futhi amafu obucabanga ukuthi azokhanya abe mpunga? Yebo baningi abanye.
Ngakho-ke, umbuzo wonke umthwebuli wezithombe zomhlaba awubuzayo esikhathini esithile empilweni yakhe uthi: Ungakwazi yini ukubikezela ithoshi? Singazi kanjani 100% ukuthi ukuphuma noma ukushona kwelanga kuzoba umbukiso wemibala? Well impendulo elula yalo mbuzo ukuthi cha, akukwazi ukubikezelwa, okungenani hhayi ngokuqondile.
Kodwa yebo, kunezici eziningi ezingabangela lesi simo. Uma usuziqonda lezi zici, ungazama ukubikezela ukuphuma nokushona kwelanga okumangalisayo futhi ukuthwebule ngekhamera endaweni yakho oyintandokazi ngaphambi kokuthi kwenzeke.
Uma amafu engekho, ngaphansi kwezimo ezijwayelekile, amandla okubomvu nokuwolintshi ekushoneni kwelanga makhulu kunaphakathi nokuphuma. Lokhu kungenxa yokuthi kunezinhlayiya eziningi ezihamba emoyeni ntambama, ngoba ukuyaluza okunesiyaluyalu emini kukhulu kakhulu eduze nomhlabathi. ukuthi ebusuku, izinto ezengeziwe zibalekela emkhathini ohlakaza ukukhanya.
Iziqhumane zezintaba-mlilo zikhiphela izinhlayiya eziningi kuyi-stratosphere kangangokuthi zisakazeka ngokushesha ezweni, okubangela ukushona kwelanga okumangalisayo nokuphuma kwelanga, kwezinye izimo izinyanga. Lezi zibani zibonakala ngemibala yesibhakabhaka evezwe emidwebeni eminingi evela ezinkathini ezihlukahlukene, ukusungula ukuxhumana okuthakazelisayo phakathi kokudweba nesimo sezulu.
Isibhakabhaka esibomvu asibangelwa ukuba khona kwezinhlayiya ezinemvelaphi yentaba-mlilo emkhathini, kodwa kungenxa yokuhlakazeka kokukhanya kwakusihlwa lapho amafu evimbile. Ezikhathini eziningi, ukuthi la mafu ajwayele ukuhlotshaniswa nangaphambili kufakazela isaga esishiwo ekuqaleni ("Candilazo ekushoneni kwelanga, amanzi ekuphumeni kwelanga").
Isazi sesimo sezulu saseBrithani u-Alan Watts saphawula: “Isibhakabhaka sasekuseni sisibonisa kangcono isimo sezulu kunasekuhwalala. Isibhakabhaka emkhathizwe wasempumalanga kufanele sicace futhi amafu abe phezulu. Lokhu kwenzeka lapho izindawo ezishisayo noma izithiyo ziya empumalanga. Isimo, ngakho-ke isibikezelo singesesimo sezulu esibi. Ukuhlola okwenziwa eLondon ngawo-1920 kwabonisa ukuthi ukuntwela kokusa okuguquguqukayo kwalandelwa yimvula emahoreni angama-24 alandelayo amaphesenti angu-70 esikhathi, nokuthi ukuhwalala okushisayo kwakulandelwa isimo sezulu esomile njalo nje.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana ne-candilazo nezici zayo.
