Usuku Polar - ubusuku Polar

Akukho lula ukucinga ukuba emini ihlala iiyure ezingaphezu kwama-24, ukuba akazange indawo ebusuku usoloko ukukhanya esitratweni. Okanye, ngokuchasene - lonke ixesha ebusuku, ubumnyama, ukubanda. Kodwa indlela kungenxa imida yangaphakathi ye-Arctic Circle.

Usuku Polar - ixesha apho ilanga ngaphezu kolundi kwaye akayi kuba ngaphezu kwesinye imini. Le nto ibonakala imimandla ezibandayo ukuya emantla Arctic Circle kunye ngezantsi Antarctic Circle.

ngosuku Polar kunokwenzeka ngenxa moya sentshinyela komhlaba notyekelo ngokuphathelele moya ka baza nama-23 ° 26 '. Kuthatha phantse ziintsuku ezimbini kwi-Arctic Circle kwaye kwandisa ezinezinga eliphezulu ukuya kwiintsuku 186 kwi-pole. I imfutshane ukunyamezela inkululeko kwe-65 ° 43 '. Ixesha elide - e North naseMzantsi. Apho, ubude baso iinyanga ezintandathu. Kwi the North Pole , uqala nge-17 Matshi kwaye sihlala de-25 Septemba. Kwaye South Pole ithatha malunga-20 Septemba ukuya kwi-22 Matshi. Ebudeni polar imini ilanga akezi yonke imihla kunina, kodwa yenza isangqa ngaxeshanye kunina. Ukongeza, le ngxaki yokusetyenziswa refraction ivumela ukuba sigcine phambi kwelanga ngexesha elinye kuzo zombini izibonda iintsuku eziliqela kumqolo phambi nasemva kokuba equinoxes.

Ubusuku polar kwenzeka kufuphi kwicala olungaphandle Arctic Circle. Ngeli xesha, akukho ilanga esibhakabhakeni ngaphezulu ngemini. Overnight umda rhoqo ehlabathini Arctic Circle Latitude nama-73 ° 5 'kwi-South. Le ubusuku nobuhlala ubuninzi iintsuku 178.

Qala kunye nexesha iintsuku ezibandayo kanye ubusuku eyahlukileyo kwiindawo ezahlukeneyo. Kwakhona, iimeko zemozulu ezahlukileyo kuvandlakanywa kuzo. Oku kungenxa yokuba indawo yabo elithile inkululeko. Umzekelo, emantla, ekwincamzwe, ubusuku polar ithatha 30 Novemba ukuya kuJanuwari 13; Murmansk iqala ngoDisemba 2 kwaye iphela ngoJanuwari 11; Polar Zory (imozulu ukuba ubusika ongqwabalala kakhulu) ukuhlangabezana ngoDisemba 21, bathatha 23 enyangeni leyo.

Njengoko sele sibonile, la abe ubude malunga 186 - 178 iintsuku, oko kukuthi, kwi izibonda ithatha isiqingatha mini, isiqingatha sonyaka - ubusuku. Kwaye la maxesha anoxanduva iimeko zemozulu emhlabeni. Akukho ayisekho amaxesha amane ngonyaka, kodwa ehlotyeni kuphela phantsi kwemiqathango ethile ngokwahlukana (ngomhla polar) kunye ebusika (xa ubusuku polar). Kwaye kwenzeka ntoni iplanethi yethu ngexesha la maxesha?

Ehlotyeni yomnye izinti yoMhlaba ejongene ilanga yaye akayi kungena izithunzi, nangona ukujikeleza umhlaba ehlabathini axis yayo. Kule sayithi - ngosuku ezibandayo. Kodwa akukho ngathi asetyenziswa ukumbona. Kakade ke, asiyiyo inxalenye mini, kuba ithatha iinyanga ezintandathu. Ekubeni esibondeni sibhekiswe, yesikhanyiso, ngoko, oko, ilanga udakada kunina, kwaye esihamba kuyo.

Ngelo kwipali icala kukho imeko eyahluke ngokupheleleyo. Ngenxa yokuba ngelo xesha ukuba phantse sisiqingatha ngonyaka komthunzi rhoqo ebusuku uya kuyo. Ilanga aliveli ngaphezu kolundi.

Nje phambi kokuqala kosuku polar pole "udakumbile" ivela ngumkhuba umdla yendalo - ezimibalabala aurora. Xa kwenzeka ngeenxa kuba lula njengoko phantsi inyanga le igcwele. Northern Lights - nje wayekubona, kodwa kumnandi! abantu Zingaphi iphupho ubuncinane kanye ukumbona ubomi!

Ezimibalabala livela kwi phezulu emoyeni ngenxa intsebenziswano lo mhlaba otsalayo komhlaba kunye amasuntswana yesiqalo. Lo kukhanya umoya nomphakamo km-60 ukuya ku-1000 ngohlobo imiqadi arcuate, amalengalenga, izithsaba. Oko kuza kujongwa izibonda kuzo zombini zifaka, kodwa ngegalelo lazo, kuxhomekeka inkululeko. Uthatha imizuzu emininzi iintsuku eziliqela yaye angavela kuphela esibhakabhakeni ebusuku ngamaxesha ahlukeneyo enyakeni.
