Indlela siyiqonde inkulumo "ilanga wawudlondlobele khona"

On usuku ehlobo kushisa, lapho ngaphandle esinamafu thina uphelé ekushiseni, sivamile ukuzwa inkulumo ethi "ilanga wawudlondlobele khona." Ngo ukuqonda kwethu lokhu ukuthi umzimba wasezulwini itholakala endaweni ephakeme kunazo efudumele kakhulu, omunye angase athi ngisho, scorches umhlaba. Ake sizame idiphu kancane kwezokuhlolwa kwezinkanyezi nesayensi ukubhekana ngaphezulu le nkulumo futhi kanjani ukuqonda kwethu le nkulumo iyiqiniso.

okucishe kufane nalokhu latitude

Ngisho ngohlelo esikoleni, siyazi ukuthi eplanethini yethu kukhona parallel okuthiwa ezingasaziwa ezingabonakali (ngengqondo) umugqa. khona wabo ngenxa ngemithetho eyisisekelo yakulelo geometry yemvelo, kanye nolwazi, la ukufana kanjani ezidingekayo ukuze baqonde isimo sendawo yonke inkambo. It ihlukaniswe yaba ezintathu umugqa ezibaluleke kakhulu - yenkabazwe, ezishisayo kanye Ne-Arctic Circle.

yenkabazwe

Yenkabazwe ibizwa ngokuthi i-engabonakali (esinikelweko) umugqa ehlukanisa imbulunga yethu ewumhlaba ibe ama- ezimbili ezifanayo - aseNingizimu naseNyakatho. Sekuyisikhathi eside kwaziwa ukuthi uHlelo Umhlaba akuyona ezinsikeni ezintathu kukholakala endulo, futhi isimo eyindilinga futhi, ngaphezu ezinyakazayo emhlabeni Sun, uzungeza kuma-axis awo. It kuvela ukuthi parallel ende kunazo zonke emhlabeni, njengoba sasinothando obuphelele lezingalo eziyizinkulungwane 40 km, -. Kuyinto yenkabazwe. Ngomqondo onabile, kusukela iphuzu nezibalo buka, yonke into icacile, kodwa kunendaba for geography? Futhi lapha, ukubukisisa eduze, kuvela ukuthi kuleyo ngxenye iplanethi, esemgwaqweni phakathi ezishisayo, uthola kakhulu ukushisa kwelanga kanye nokukhanya. Lokhu kungenxa yokuthi lesi sifunda Zomhlaba njalo isiphendukela ngasetendeni ilanga, ngakho imisebe abawayo cishe thwi. Kule kusobala ukuthi izindawo ezisenkabazwe emhlabeni has izinga lokushisa eliphezulu kakhulu futhi umswakama-laden emoyeni uquqaba ukudala ukuhwamuka eqinile. Ilanga wawudlondlobele khona enkabazwe kuyinto kabili ngonyaka, ukuthi ngokuphelele kukhanya iqonde phansi. Ngokwesibonelo, alilokothi kwenzeka into enjalo eRussia.

ezishisayo

On wonke kukhona ezishisayo eNingizimu nase-Nyakatho. Kuyaphawuleka ukuthi ilanga wawudlondlobele khona lapha kanye kuphela ngonyaka - ngosuku olufushane kunazo zonke. Lapho okuthiwa ngenjikalanga yasebusika - 22 Disemba, ngaphendukela kuyo ilanga ngangokunokwenzeka kuyinto Nenkabazwe eningizimu, futhi ngo-June 22 - kunalokho.

Ngezinye izikhathi, Southern naseNyakatho ezishisayo kuthiwa yaqanjwa nemilaza yezinkanyezi zomgamu wezulu, okuyinto endleleni ilanga kulezi zinsuku. Ngokwesibonelo, Southern evamile ngokuthi Tropic of Capricorn naseNyakatho - Cancer (Disemba futhi Juni ngokulandelana).

imibuthano polar

Arctic Circle ubhekwa kufana ngokuphawulekayo nalokho okwenzeka, ngenhla okuyinto lesi senzakalo saphawula Njengoba kwakuba ubusuku polar noma usuku. Indawo latitude, okuyizinto imibuthano polar, futhi uye ngempela incazelo zezibalo, kuba lokususa 90 ° ukuthambekela-eksisi kule planethi. Ngomhlaba, lesi silinganiso uyalingana emibuthanweni polar 66,5 °. Ngeshwa, abakhileyo ezindaweni ezinezinga lokushisa elithokomele awukwazi ukubona lezi zenzakalo. Kodwa ilanga wawudlondlobele khona e parallel elihambisana kwe-Arctic Circle, umcimbi ngokuphelele zemvelo.

Iqiniso eyaziwayo

Umhlaba akusho yima unganyakazi futhi, ngaphezu ezinyakazayo emhlabeni Sun, nsuku zonke lumayelana axis awo. Kuwo lo nyaka, sibona indlela ekushintsheni longitude kosuku, izinga lokushisa emoyeni ngaphandle kwefasitela, kanye unake kakhulu ungakwazi uqaphela ushintsho isikhundla zezulu. Ukuze 364 izinsuku Umhlaba uya indlela ngokugcwele njengoba uzungeza ilanga.

Imini nobusuku

Lapho sithola emnyama, okungukuthi ebusuku, it is wathi ukuthi ilanga ngesikhathi esinikeziwe ihlanganisa Nenkabazwe ezahlukene. Kukhona ngempela umbuzo okunengqondo, kungani usuku akulingani isikhathi ebusuku. Iqiniso liwukuthi trajectory of the indiza lena akuyona neze engeli ilungelo-eksisi eMhlabeni. Ngempela, kulesi simo, ngeke sibe zonyaka lapho ratio ubude imini nobusuku izinguquko.

Ezinsukwini 20 Mashi bebheke ilanga egoba North Pole. Khona-ke, cishe emini ku yenkabazwe, ungakwazi ngempela ukuthi ilanga wawudlondlobele khona. Kulandelwe izinsuku lapho izindawo enyakatho ngaphezulu waphawula isimangaliso esifanayo. On 22 Juni ilanga wawudlondlobele khona isendaweni Tropic of Cancer e Nenkabazwe lolu suku ubhekwa phakathi ehlobo, futhi i-longitude esiphezulu. ngenjikalanga mkhuba - ukuzimisela ajwayeleke kunawo wonke kithi.

Into ezithakazelisayo wukuthi emva kwalolo suku konke okwenzekayo futhi, kodwa oda reverse, futhi uyaqhubeka kuze kube ngomzuzu lapho umugqa nenkabazwe emini, ilanga wawudlondlobele khona futhi - lokhu kwenzeka mhlaka-23 Septhemba. Ngalesi sikhathi, phakathi ehlobo iqala Nenkabazwe oseningizimu.

Kusukela konke lokhu kusobala ukuthi lapho ilanga seliphansi wawudlondlobele khona enkabazwe, emhlabeni wonke nobusuku obungamashumi amane ubude - amahora angu-12, ubude efanayo isikhathi esilinganayo ngosuku. Sasivame ukubiza lesi simanga ngosuku ekwindla noma entwasahlobo ngesikhathi sokulingana kwemini nobusuku.

Naphezu kweqiniso lokuthi incazelo enembile welithi "ilanga wawudlondlobele khona," saxoxa, kusenzima kwande ukuthi sibe kumagama ukuthi lisikisela nje ekutholeni ilanga njengoba eliphezulu ngangokunokwenzeka ngosuku inikezwe.
