Masikati - nguva apo nzvimbo zuva mudenga ndiwo soro

Kuona masikati kufamba kwezuva mhiri denga, munhu kubva makarekare vakaedza kuwana tsananguro. Zvichienderana chiedza mune imwe nguva mune sangano bhizimisi uye upenyu hwezuva nezuva chamuita kuti mafungiro kwaari ave mwari. Ngano pamusoro ngoro yemoto, kuti zuva nzira mhiri kudenga, zvinoratidzwa Mutsika marudzi mazhinji. Zvinonzwisisika mugumo kufora - nguva apo zuva nzvimbo mudenga ndiwo soro, akanga achishandisa nguva.

masikati

Chii hakusi zuva inotenderera Earth, asi nekusiyana, zvakava pachena chete pakati XVI remakore. Uye mumwe vanhu vakaratidza pfungwa iyi (Copernicus), saka aiva nechokwadi chokuti inopesana pachena - kuti anogona kuonekwa pahwaro hwezuva nezuva kuti aitanga ayo bhuku mashoko heliocentric ezvinhu ayo pachena upenzi.

Zvino mudzidzi anoziva kuti chaizvoizvo sangano iri gwenya dhisiki mudenga - Kutenderera pasi kuguma kumativi ayo akabatana, kuti mumwe chimurenga nyika yedu zvakakwana kunoita pazuva, kuti nzvimbo zuva pamusoro jengachenga chero nguva hakubvi chete pamusoro pakona pakati kutenderera kusvikira ezvokuvhenekesa. Zvinonzi kuchinjwa nzvimbo inogarwa Panyika panguva gore-refu marapirwo akapoteredza zuva. Winter kuchamhembe hemisphere kuti nyeredzi yedu inokwira masikati kuvatumwa muzhizha.

pamusoro-soro

Kuti zvakarurama kuziva kana nzvimbo zuva mudenga ndiwo soro, zvakakosha kunzwisisa, sezvo kuyerwa chinzvimbo ichi. Kana yakakwirira ndima gwenya dhisiki muzinda masikati iri chete kumusoro musoro (kana danda rakabayirwa pasi vertically, ndokuupfurira mumvuri razero), zvinoreva kuti mucherechedzi iri mudunhu rinowanzopisa.

Muna Northern Hemisphere ari pamusoro-soro nguva - chikuru kwekona pakati declination richipenya jengachenga masikati, kana nzvimbo zuva masikati - ochinja kuchamhembe kumaodzanyemba hemisphere zviri mukufamba kwegore haachatauri downwards kurutivi rwezasi. Main chikonzero wepagore kuchinja kukwirira kwezuva pamusoro jengachenga kuti masikati - axial rakarereka yose kusvikira orbital ndege. Zviri kuramba uye kuenzana 23,5 °.

Winter uye chirimo

Izvi imhaka yakatenuka uye kuchinja mwaka iri redu. Reference pfungwa dziri tsamwisa zvenyeredzi yechando kana chirimo kwezuva ndiyo pfungwa. Mune Northern Hemisphere, zhizha kwezuva - 21 uye 22 June. Zuva iroro, zuva soro mudenga. The angled pamusoro kuitika chezuva pamusoro pemvura puraneti akadaro kuti rinopisa kumusoro zvakanakisisa. Zvishoma nezvishoma kudziyirwa miviri hombe remvura uye nenyika uye mhepo tembiricha rinobuda. Northern Hemisphere panguva ino akatarisa zuva.

In yechando, 21 uye 22 December, kuchamhembe neequator masikati, kana zuva nzvimbo mudenga ndiwo soro, unomutswa pamusoro jengachenga pane risingamboshandisi urefu, kana tikatora kuchinja chinoratidza ichi pamusoro gore. pose nzvimbo pasi Wedu apo muAtlantic nenzira huru nyeredzi dzaro, ichibereka ruduku nhamba kunobatsira kupisa. Kumaodzanyemba hemisphere, zvose zvinoitika zvakasiyana chaizvo.

Ichokwadi (ezvemuchadenga) nguva

The pakuonekwa yakadai nguva vezvikwata sezvo gore, mwedzi uye zuva nokuda muchadenga zvaanorumbidza uye zvakananga novimba kudyidzana pakati nyika chete navanhu uye nechepakati nyeredzi. Division kupinda maawa, maminiti nemasekonzi ndiyo zvemasanga. Mukuru chikonzero kuti kwaita manhamba chete kwakadaro - sexagesimal chakanga chinyakare Bhabhironi rekare - akazvarirwako ano nguva dzakabatana.

Nguva kuti elapses pakati yakadururwa apo nzvimbo zuva mudenga ndiwo soro - chii chinonzi wachi - haasi kuramba rose gore. Kusiyana-siyana kwezvinhu musiyano uyu rinosvika maminitsi 30 uye anotsanangura elliptical Maumbirwe muchadenga, umo Pasi kunoita munyika. Kana kushandiswa iri tsika nguva chaiyo, zvingava kuti kusika wachi ane gogonera nzira. Zvino zvazviri zvinogoneka, asi zviri munguva yedu, apo mukuru nemazvo yaunonyanya kushandisa zviri kuitika munzvimbo dzakasiyana-siyana dzenyika, kwakadaro kwava kunyanya inoshanda.

avhareji nguva

Kuti zvaizopedza kusiyana-gore rimwe ya yokuongorora zvomuchadenga zuva, nyanzvi akatanga vanonzi "kunoreva zuva". Ichi evasingatombonamati yokungotaura pfungwa chinomirira pfungwa kuti inorondedzera chinzvimbo chiedza chedu mudenga, kuti mazuva kufamba mukati 365 zvakaenzana. Kaviri pagore, nzvimbo yaro rinobatana pakati kwezuva. Izvi zvinoitika panguva chitubu uye matsutso rinenge riine.

Nhanganyaya of "pakati Sun" zvakakonzera kushandiswa zvinobatsira mune uchidzidzira kunoreva nguva, zvimwe inonzi veHurumende. Saka, nezuva, zvimwe pane mazuva rinenge riine, wegumi nemiviri amurove maawa ari masikati hakurevi nguva zuva apo zuva nzvimbo iri kumusoro. Kuverenga nguva yakadai mukati chikamu chechipiri, shandisa "mukana wokuti vanhu vanga nguva", iyo vaumbe mashoko kunobva nenzvimbo Coordonatele maduramazwi nzvimbo.
