Hazvisi nyore kufungidzira kuti kwaedza rinovapo maawa anopfuura 24, kuti akanga asina akatsiviwa usiku mumigwagwa dzose chiedza. Kana, nekusiyana - zvose nguva usiku, rima, pachando. Asi nzira ndezvenguva dzakawanda miganhu kweArctic Circle.

Polar Day - munguva umo zuva rinopfuura pajengachenga uye anoita zvinopfuura rimwe zuva kupinda izvozvo. Fani iyi inogona kuchengetwa mune polar kumatunhu kuchamhembe kweArctic Circle uye kumaodzanyemba Antarctic Circle.

Polar zuva zvinogoneka nokuda Equatorial ndege paNyika mafungiro panyaya ndege yacho ecliptic dzinenge 23 ° 26 '. Rinotora anenge maviri mazuva ari kweArctic Circle uye inowedzera yepamusorosoro latitudes mazuva 186 panguva namatanda. Pfupi izvozvo panguva Latitude anenge 65 ° 43 '. Chakarebesa - at North uye South Poles. Ikoko, ayo nguva mwedzi mitanhatu. At vokuNorth Pole , anotanga musi 17 March uye rinovapo kusvikira 25 September. Uye South Pole runogara anenge 20 September kusvika 22 March. Munguva polar zuva hazviuyi ose zuva kune mujengachenga, asi zvinoita denderedzwa akaererana jengachenga. Mukuwedzera, Chiitiko pakati refraction kunotibvumira kuchengeta pamberi zuva panguva iyoyo pane zvose mapango kwemazuva mumutsetse pamberi uye mushure equinoxes.

The polar usiku kunoitika pedyo rokunze divi kweArctic Circle. Panguva iyi, hapana zuva mudenga kupfuura zuva. Evening kuramba muganhu kumativi kweArctic Circle Latitude iri vanenge 73 ° 5 'kuna South. usiku huno hunogara vaifanira mazuva 178.

Tanga uye nguva yose polar mazuva nousiku zvakasiyana kuti nzvimbo dzakasiyana. Uyewo, mamiriro dzakasiyana okunze kuchengetwa mazviri. Izvi imhaka nzvimbo yavo pane imwe Latitude. Somuenzaniso, kuchamhembe, Polar, ari polar usiku kunotora November 30 January 13; Murmansk inotanga musi December 2 uye inoguma musi January 11; Polar Zory (ekunze kuti chando kunonyanyisa chaizvo) kusangana yayo December 21, uye vakaperekedza 23 romwedzi iwoyo.

Sezvataona, izvi mananara vane kureba vanenge 186 - 178 mazuva, kureva panguva matanda runogara hafu zuva, hafu gore - usiku. Uye izvi nguva ndivo okunze pasi. Hakuna mwaka mana gore, asi chete conditionally vakaparadzana zhizha (ari polar zuva) nechando (kana usiku polar). Uye chii chiri kuitika redu panguva izvi nguva?

Muzhizha rimwe matanda Pasi yakatarisa zuva uye asingauyi kupinda mimvuri, pasinei nyika yacho majana kumativi ayo akabatana. On nzvimbo iyi - the polar zuva. Asi hazvisi akafanana isu anoshandiswa kumuona. Handiti haisi chikamu zuva, nokuti inogara kwemwedzi mitanhatu. Sezvo danda inoendeswa chinovheneka, zvino, maererano, zuva rinomuvanza seri mujengachenga, uye chinokambaira nayo.

At nevakomana danda pane zvakasiyana zvachose mamiriro ezvinhu. Nokuti panguva iyoyo akanga kusvika hafu gore mumumvuri kugara usiku anoenderera pairi. Zuva asimo pamusoro jengachenga.

Pazvinotanga of polar zuva mu "kwakakwidibira" danda Nguva pfupi asati rinowanika zvinonakidza dzinongoitika chakajairika - the Aurora borealis. Pazvinoitika kumativi zvinova kupenya sezvo pasi rejenaguru. Northern Lights - chete ane Manyiminya chaizvoizvo, asi sei zvinofadza! vanhu vangani hope kanenge kamwe kumuona kurarama!

Borealis kumbowanikwa rokumusoro mumhepo nokuda kubata simba remagineti enyika yepasi pose inoramba. Izvi mhepo chomwedzi ari nekukwirira 60 kusvika 1000? Km muchimiro arcuate matanda, maketeni, korona. Inogona kuonekwa panguva matanda acho hemispheres, asi pamwe kusiyanisa zvokutamba, zvichienderana Latitude. Rinotora kubva maminitsi akawanda kuti mazuva anoverengeka uye anogona chete kuonekwa mudenga usiku panguva dzakasiyana kwegore.
