Dihora tse motšehare ka Moscow le St. Petersburg

Lentsoe "letsatsi" le bolela lintho tse peli. Pele - ena ke nako ea letsatsi leo ka lona leseli le ka ntle, 'me ea bobeli - e le karolo e khanyang ea letsatsi le letsatsi letseno nako ea Lefatše. Litsebi li lumela hore lihora tse le motšehare - nako ho tloha ha letsatsi le chaba ho le likela.

Lefatše ba chenchana selekane e sekamisoa, kahoo ka mor'a selemo, bolelele tsa motšehare. Mariha letsatsi ke lekgutshwane, le bolelele ba eona e fapana le bolokolohi. Karolong e ka leboea, ka letsatsi le mariha selemong leseli ke dihora tse 4-5, 'me ba bang kaofela ea nako e - lefifi. Empa ka ho eketsehileng leboea letsatsi ha etsahala ho hang - bosiu Polar, empa nakong ea lehlabula ho robala hang - sa bosiu. Hang letsatsi le o tsoile ka mor'a fellang teng, 'me mantsiboea o ile a qala hoo e ka bang hang-hang' me ba fela - letsatsi le chaba hape.

Empa ho sa tsotellehe hore tse ngata e ile ea nka lihora tse motšehare, lihora tse 6 kapa tse 18, bosiu e tla ba teng ka feela nako e lekaneng hore nka letsatsi le lihora tse 24 - almanakeng ka letsatsi. 'Me haeba bosiu ka June 5:00 feela, letsatsi le e ne e tla 19. Empa ho na le linako tse thahasellisang ka selemo almanaka eo. Ka 2010 - 2020 lilemo tsena tse 20 tsa Tlhakubele 20-21, June 22-23, September, 'me December 21-22. Matsatsing ana, ka March le September, bosiu le motšehare li lekana ka lefatše. Ba ba bitsoa - matsatsi a ea selemo le hoetla equinox. Leha, haeba u ho nahana ka ketsahalo ea refraction tsa tiske letsatsi le boholo ba eona (0.5 arcminutes), bakeng sa nako ya letsatsi le tlhaho, ho sebedisa liphello tsena meleng, e eketsa metsotso e seng mekae ho feta. Ka mor'a lihora tse motšehare - nako ho tloha ponahalo ea ka bohale e ka holimo ea tiske hae letsatsi ka holimo fellang teng pele ho tloha ya tlaase (mabapi le hoseng) tsoa k'honeng ea fellang teng, 'me e sa ntse e metsotso e' meli ea letsatsi tiske sisinyehang. 'Me e ke ka equator. Ka latitudes rona e mong 3-4 metsotso e kapa ho feta. Ho phaella moo, ka lebaka la lipono tse makatsang tsa refraction - refraction oa mahlaseli khanya sepakapakeng ho - letsatsi le se bonahalang, le hoja, ho ea ka dipalelo jeometeri, e ntse e ka tlase atamela. E tšoanang e ketekoa ha letsatsi le likela.

A 20-21 June - lehlabula letsatsi le tsoang tlung, ha letsatsi le chaba ho bophahamo khōlō ka ho fetisisa, 'me letsatsi le telele ka ho fetisisa. Libakeng Polar ea bosiu e khutšoanyane haholo le "e tšoeu" ka nako ena, 't. E., Ntle le meso lefifi. Empa ka December 21-22 - letsatsi lekgutshwane le bosiu ke telele ka ho fetisisa. Le libakeng Polar ho ea ka leboea le ea letsatsi ka 'na sa qala. Empa ka lehlakoreng le leng la lefatše, Australia, South Africa le Amerika Boroa ke hantle bo fapaneng.

Biorhythms le motšehare

Nature e ikamahanya le maemo tse phelang e phelang ho fetola nako leseli le lefifi tsa letsatsi. Ha phoofolo e (le batho) libeke tse seng kae ho boloka ka "lihora tse 12 ka letsatsi, 12 - bosiu", 'me joale ho panya ha leihlo ka isoa puso ea "lihora tse 18 la leseli le lihora tse 6 lefifing," joale qala ho kena-kenana le mafolo-folo falimehe le ho robala.

Ka mokhatlo oa batho, mokhathala oa sefofane ka potoloho ea letsatsi le letsatsi ho etsa hore khatello ea kelello, ho fihlela ho ntshetsopele ya mafu a - ho tepella maikutlo, lefu la ho hlobaela, lefu la pelo le methapo ea mali, 'me esita le lefu la kankere. Ho na le e ne e esita le khopolo ea "ho tepella maikutlo ka linako tse itseng" tse amanang le bolelele ba lihora tse motšehare tsa mariha.

Ka latitudes fapaneng - fapaneng khanya letsatsi. Moscow, ho ba likhato tse 55 tsa leboea bolokolohi, o na le letsatsi leseli la lihora tse 7 ka December le January ho 17 ka June le July.

Khanya letsatsi St. Petersburg hape ho itšetlehile ka nako ea selemo. Le ka St. Petersburg e teng ka likhato tse 60 ka leboea bolokolohi, bolelele ea letsatsi mona ka June ba ka bang tsa 18.5 lihora. Sena se etsa phello ea White masiu a ha letsatsi le ka bokhutšoanyane feela siea. Molao masiu tšoeu ho qetela ho tloha ka May 25 ho ea ho la 17 July. Empa ka December le January lefifi ka hora ea bohlano ka shoalane.
