Cabanga ukuhlala kusihlwa kuze kube izinyanga ezintathu
Ubusika be-Polar eScandinavia kuyinto ejabulisayo kwabakhambayo. Phakathi nobusuku be-polar Enyakatho yeScandinavia , kukhona ukukhanya kwe-twilight, ikakhulukazi, kuye ngokuthi indawo. Lokhu kungahlala izinyanga ezimbili kuya kwezintathu.
Enyakatho yeHormerfest eNorway (idolobha elisenyakatho yezwe elisenyakatho), ilanga lifihliwe amahora angu-1 500. Noma kunjalo, akuyona into eqondile njengoba kungase kuzwakale. Phakathi nobusuku be-polar, i-landscape ihlanganiswe iqhwa, ibonisa kahle ukukhanya kwezinkanyezi ezingenhla.
I-Twilight phakathi nobusuku ngokuvamile inikeza ukukhanya okwanele okufundwa ngu. Ngaphezu kwalokho, iwindi lesikhathi sobusuku be-polar yisikhathi esiphelele sokubuka izibani ezisenyakatho (i-Aurora Borealis) .
Yiziphi Izinkanyezi Zama-Polar?
Ubusuku obumnyama buyihora ezingama-24 phakathi kwamibuthano ye-polar. Ukungaqondani okudumile ukuthi izindawo ezinama-polar amaningi (owaziwa nangokuthi ilanga eliphakathi kwamabili) nazo zithola ubusuku obukhulu kakhulu. I-Twilight yenza lokho kungamanga.
E-Kiruna, eSweden, ubusuku obumnyama buhlala cishe "izinsuku ezingu-28". Ilanga eliphakathi kwamabili lihlala cishe izinsuku ezingu-50.
Kunezinhlobo ezahlukene zobusika obuphakathi, njengebusuku be-polar besibhakabhaka (ubusuku obuqhubekayo obungenayo i-twilight astronomical twilight) noma ubusuku obunama-polar, lapho isibonakaliso sokukhanya kwesikhashana senzeke phakathi nosuku.
Izinkanyezi Zama-Polar Zinde Kangakanani?
Ubude bomnyama buhluka emahoreni angu-20 e- Arctic Circle kuya ezinsukwini ezingu-179 ezigodini. Ngenxa yokuhlwa, akuyona yonke le sikhathi empeleni ubusuku be-polar.
Gcina ukhumbule ukuthi isikhathi esiphezu kwezingqungquthela ezithinta izingongolo kuthiwa yizinsuku ezingu-186. I-asymmetry ezinombalwa ivela ezinsukwini ezinelanga eliyingxenye libalwa ngokuthi "usuku nosuku."
I-Polar Nights ingaba nzima
Isikhathi sobusuku be-polar singaba nzima kuwe, ngaphezulu kunezinye izenzakalo zemvelo, futhi kungabangela ukucindezeleka ukukhanya kwabahambi abangasetshenziselwa ubumnyama.
Abahambi abanenkinga yokuphelelwa yinkinga ikakhulukazi bayangena. Uma ungabaza, buza udokotela ngaphambi kokuba uhambe noma uthole usizo lwezokwelapha lapho uya khona. Imibhede yokuncibilikisa ingasiza ukugcwalisa isidingo somzimba sokukhanya. Izinsuku ze-polar (noma phakathi kwelanga eliphakathi kwamabili) zithinta abantu futhi, kodwa ngokuvamile akufani neze nobusuku be-polar.
Enye i-Phenomena yemvelo yaseScandinavia
Okuphambene (lapho ilanga lihlala ngaphezu komkhathi) libizwa ngokuthi usuku lwe-polar (noma phakathi kwamabili ilanga). Usuku lwe-polar uma ilanga lingabeki isikhathi samahora angaphezu kwangu-24. Esinye isenzakalo esingavamile saseScandinavia yizitshalo ezisenyakatho (i-Aurora Borealis), okuvula imifino nembala engavamile.
Vakashela iTromso, eNorway
Ubusika bezinkukhu kusukela ngoNovemba kuya kuJanuwari eTromso, eNorway, okuyindawo engamakhilomitha angu-200 enyakatho ye-Arctic Circle. Phakathi nale nkathi ebusika, ilanga alisuki - nhlobo. Lokhu kwenza i-Tromso indawo evamile ukuvakashela uma ufuna ukuzwa ubusuku be-polar ngokoqobo.
I-Tromso nayo inesikhathi seMidnight Sun eqhuba ngoMeyi ngoJulayi. Phakathi nalesi sikhathi, ilanga alingazibekela ngokugcwele. Kungaba esinye isikhathi esithakazelisayo sonyaka ukuvakashela iTromso.
