Sei kunzwisisa mashoko okuti "zuva pa pamusoro-soro kwaro"

Nezuva rinopisa muzhizha, kana kunze ari ramakore isu dzikaziya pakupisa, tinowanzonzwa mashoko okuti "zuva panguva yayo pamusoro-soro." Mukunzwisisa kwedu ichi ndechokuti muviri vokudenga riri yakakwirira uye kupfuura kudziya, mumwe vangatoti, unopisa pasi. Ngatiedzei zvishoma Dip nezvenyeredzi uye kubata zvakawanda aya uye kunzwisisa kwatinoita mashoko aya sei zvechokwadi.

Rakafanana Latitude

Kunyange purogiramu chikoro, tinoziva kuti pane redu pane anonzi yakafanana, izvo zvisingaonekwi (zvekufungidzira) mutsetse. Kuvapo kwavo nokuda mitemo inokosha geometry uye wefizikisi, uye ruzivo, sei kufanana izvi zvinokosha kuti tinzwisise nzvimbo yose kosi. Rakakamurwa zvitatu chinokosha mutsetse - neequator, dzinopisa uye kweArctic Circle.

ikweta

Neequator anonzi risingaoneki (notional) mutsetse runoparadzanisa redu huviri akafanana hemispheres - South uye North. Kwenguva yakareba zvave kuzivikanwa kuti Pasi haasi pamusoro pembiru nhatu akatendwa kare, uye ane idenderedzwa chimiro, uye kuwedzera inofamba vakapoteredza Sun, rotates yawo akabatana. Zvakaratidza kuti wakarebesa kufanana munyika ane kureba vanenge zviuru 40 km -. Hazvina neequator. Pfungwa, kubva kwemasvomhu nemaonero, zvose zviri pachena, asi zvine basa kuti jogirafi? Uye pano, pamusoro kunyatsoongorora, zvinoitika kuti chikamu nyika, iro riri pakati dzinopisa, anowana kupfuura zuva kupisa uye chiedza. Izvi imhaka yokuti nharaunda iri Pasi riri tagara kurutivi zuva, saka mwaranzi vanowa anenge vertically. Kubva ichi zvinoreva kuti ine nzvimbo panyika ine soro tembiricha uye unyoro-akaremerwa mhepo makore pave simba kwemvura. Zuva iri pamusoro-soro kwaro panguva neequator iri gore kaviri, kuti zvachose inopenya ikarurama. Somuenzaniso, harimbowaniki kutanga zvakadaro Russia.

dzinopisa

On pose pane Southern uye Northern dzinopisa. Zvinokosha kucherechedza kuti zuva riri kwaro pamusoro-soro pano kamwe chete pagore - nezuva rokutanga kwezuva. Apo Yaunoti kwezuva muchando - December 22, maximally akatendeukira kune zuva ndiye Southern Hemisphere, uye June 22 - pamusoro zvinopesana.

Dzimwe nguva, Southern uye Northern dzinopisa vanonzi mushure dzokudenga, riri mugwara zuva mumazuva iwayo. Somuenzaniso, Southern conventionally kunzi Tropic of Capricorn uye North - Cancer (December uye June azvaitwa).

polar yeChina

Arctic Circle runoonekwa kuva yakafanana, pamusoro izvo chiri kwakacherechedzwa sezvo polar usiku kana zuva. Location Latitude, zvinova polar yeChina, wakangamwirawo kwazvo kwemasvomhu tsanangudzo, zviri kubvisa 90 ° zvaidiwa nyika kuti akabatana. Nokuti Earth, mutengo ichi akaenzana polar yeChina 66,5 °. Zvinosuruvarisa vagari unozvidzora latitudes haagoni kuchengeta izvi zvakavapo. Asi zuva iri pamusoro-soro kwaro kufanana chaienzanirana kweArctic Circle, chiitiko zirokwazvo chaivo.

chokwadi tsika ruzivo

Nyika haamiri achiri uye, kunze inofamba vakapoteredza Sun, zuva inotenderera ayo akabatana. Mugore, tinoona kuti kuchinja Longitude zuva, mhepo tembiricha kunze nepahwindo, uye zvikuru dzakateerera anogona kuona shanduko pachinzvimbo senyeredzi dzokudenga. Nokuti 364 mazuva Pasi anoenda zvizere nzira kumativi zuva.

Day uye usiku

Kana tine rima, kuti ndiye ari usiku, naro akati kuti zuva ari kupiwa nguva penguva rinofukidza yakasiyana hemisphere. Pane chaizvo mubvunzo musoro, nei zuva haana kuenzana ya usiku. Chokwadi ndechokuti trajectory ndege haako dzinoita kuti akabatana paNyika zvakanaka. Zvechokwadi, muchiitiko ichi, tingadai tisina nemwaka umo nhamba nokureba masikati nousiku kuchinja.

Mumazuva 20 March nenzira zuva anokotama North Pole. Zvadaro, panguva inenge yechitanhatu iri mudunhu rinowanzopisa, unogona chaizvo kutaura kuti zuva iri kwayo pamusoro-soro. Vakatevera mazuva apo zvikuru kuchamhembe nzvimbo vakachengeta yakafanana chinoshamisa. Nechekare musi waJune 22, zuva iri pamusoro-soro wayo Tropic kenza kuchamhembe hemisphere nhasi ichaongororwa kuva pakati kwezhizha, uye ane kunonyanyisa Longitude. kwezuva Fani - kutsunga ndiyo avanoziva kwatiri.

The dzinonakidza ndechokuti pashure iroro zvose zvinoitika zvakare, asi nekwekupedzesera, uye anoramba kusvikira nhambo apo vakamirira neequator masikati, zuva iri kwayo pamusoro-soro zvakare - ichi zvinonyatsoitika 23 September. Panguva ino, pakati chirimo chinotanga kumaodzanyemba hemisphere.

Kubva izvi zvose zvinoreva kuti kana zuva iri pamusoro-soro kwaro panguva neequator, pasi pose usiku nguva - maawa 12, imwe urefu nguva yakaenzana zuva. Taiwanzogara kudana Fani iyi zuva mumatsutso kana muchirimo rinenge riine.

Pasinei chokwadi kuti yakarurama tsananguro pfungwa "zuva panguva yayo pamusoro-soro," takakurukura, zvichiri anonyanya tive mashoko kuti chinoreva rokuwana zuva yakakwirira sezvinobvira musi wakapiwa.
