Noon - ixesha xa indawo kwelanga esibhakabhakeni lelona liphezulu

Okwenzeka ngexesha intshukumo imini ilanga litshonile, indoda ukususela kumaxesha amandulo bazama ukufumana ingcaciso. Kuxhomekeka ukukhanya ngexesha elithile entlanganweni loshishino kunye nobomi bemihla ngemihla sibangele ukuba sengqondo nezolo elinye kuye isithixo. Iintsomi malunga inqwelo yomlilo, yenza indlela imihla ngemihla kulo lonke esibhakabhakeni, kubonakala iinkcubeko eentlanga ezininzi. Ngokusengqiqweni, luvuthondaba komjikelo - ngesiquphe xa indawo ilanga kwi isibhakabhaka enyangweni, ibe sisiseko ixesha.

semini

Yintoni na ilanga nendawo eyayisaya kuba uMhlaba, kodwa koko, kuye kwacaca mhlophe kuphela phakathi kwenkulungwane XVI. Ke kaloku omnye abantu wavakalisa le ngcingane (Copernicus), ngoko qiniseka ukuba iyaphikisana ezicacileyo - njani ukuba kwenziwa yonke imihla ukuba kokunikeza kokupapashwa kwayo amazwi kwenkqubo heliocentric engenangqondo yayo ibonakale.

Ngoku ke umfundi uyazi ukuba eneneni intshukumo disk elanga esibhakabhakeni - ukujikeleza umhlaba kubangela ngeenxa axis awo, ukuba revolution ngokupheleleyo iplanethi yethu yenza ngosuku, ukuba indawo kwelanga ngaphezu kolundi nangaliphi na ixesha kuxhomekeke kuphela kwi engile ukujikeleza ukuya sokukhanyisa. It iphenjelelwa sikhundla awayephantsi Umhlaba ngexesha unyango ngonyaka-elide ngeenxa ilanga. Ebusika kumntla ikhweyitha yinkwenkwezi yethu liphuma emini ngaphantsi ehlotyeni.

bade

Ukuze ikwazi ukubonisa ngokuchanekileyo xa indawo kwelanga esibhakabhakeni lelona liphezulu, kubalulekile ukuqonda, njengoko kulinganiswa yi kwesi sikhundla. Ukuba indawo eliphezulu enkalweni kweli ziko disk ilanga emva kwemini kubekwe ngentla nje intloko (ukuba kwipali ugxunyekwe phantsi nkqo, ngenye imini zero), oko kuthetha ukuba mkhanyo ophezu ikhweyitha.

E Northern saseNtla kwindawo bade --engile likhulu declination besikhanya phezu elundini ngexesha lasemini, okanye isikhundla ilanga emini enkulu - uqala ukuya emantla kwi ikhweyitha emazantsi ngayo apha ekuhambeni konyaka lwaye ezantsi esinga kwelasezantsi. sizathu siphambili utshintsho ngonyaka ukuphakama kwelanga ngaphezu kolundi emini - ukuthambeka yezihlunu zomhlaba ukuya moya Orbital. Kuyinto rhoqo kwaye ilingana 23,5 °.

Nobusika nehlobo

Oku kungenxa kwithambeka kunye nokutshintsha onyaka kwi kwiplanethi yethu. amanqaku esalathisi kwi kwinqanaba lohlaselo ngeenkwenkwezi ebusika okanye ehlotyeni ngenjikalanga na ingongoma. E Northern saseNtla, i-ikhweyitha zasehlotyeni - 21 ne-22 Juni. Ngaloo mini, ilanga liphezulu esibhakabhakeni. I-engile lweziganeko kwelanga phezu komhlaba planethi yenziwe ngohlobo lokuba kumo best. Ngokuthe ngcembe ukufudumala imizimba omkhulu wamanzi kunye nomhlaba kunye lobushushu lomoya avuke. SaseNtla Northern ngeli xesha ejongene ilanga.

Ebusika, 21 no-22 Disemba, ukuya emantla we-ikhweyitha emva kwemini, xa indawo ilanga esibhakabhakeni lelona liphezulu, liphuma ngaphezu kolundi ubude ubuncinane, ukuba singathatha utshintsho kwesi salathisi kulo nyaka. indawo umphezulu umhlaba wethu ngoxa ezifakwe kwicala kwenkqubo solar star engundoqo, ukuthobela elona nani lincinane ubushushu iyingenelo. In ikhweyitha wasezantsi, yonke into eyenzekayo kanye okwahlukileyo.

True (nezizayo) ixesha

Imbonakalo ezifana iiyunithi ixesha lonyaka, ngenyanga kunye imini ngenxa imigqaliselo ngeenkwenkwezi kwaye kuxhomekeke ngqo kwi intsebenziswano phakathi iplanethi olunye imiwe kunye inkwenkwezi central. Division ibe kwiiyure, imizuzu kunye imizuzwana ngokwesigqibo esicalanye. Eyona nto iphambili ukuba ukuvela amanani nje ezinjalo - sexagesimal nto leyo zemveli iBhabhiloni yamandulo - wazalwa iiyunithi kukho ixesha mihla.

Ixesha kufudumeze phakathi mzuzu xa indawo kwelanga esibhakabhakeni lelona liphezulu - into ebizwa ngokuba iwotshi - ayikho rhoqo unyaka wonke. Kunyuka kwalo mahluko ufikelela imizuzu engama-30 kwaye acacise imilo okweqanda ye komzila apho komhlaba ehlabathini jikelele,. Ukuba kusetyenziswa kulo mkhuba yexesha lenene, bekuya kufuneka udale ikloko kunye ngendlela olungalinganiyo. Ngoku kwezobuchwepheshe kunokwenzeka, kodwa ke ngexesha lethu, xa ngendlela eliphezulu ungqamaniso iziganeko ezenzeka kwindawo ezahlukeneyo zehlabathi, inkqubo enjalo ingakumbi aluncedo.

ixesha avareji

Ukuze lulungisa umahluko ubude kunyaka omnye womhla ngeenkwenkwezi, izazi laqalisa babizwa ngokuba "ilanga kakubi". Lo gama nje theoretical imele ingongoma ichaza isigxina ukhanyiselo lwethu esibhakabhakeni, ukuze yolulwe imihla intshukumo ngaphakathi 365 ngokulinganayo. Kabini ngonyaka, indawo yayo ihambelana embindini kwelanga. Oku kwenzeka ngexesha entwasahlobo ekwindla yasentwasahlobo.

Kukwaziswa kwe "phakathi Sun" kukhokelele ekusetyenzisweni lula ngakumbi practice kuthetha ixesha, ebizwa yoluntu. Ngoko ke, ngosuku, ngaphandle iintsuku nobusuku, iiyure ugwayimbo yeshumi elinambini emva kwemini akuthethi ixesha lemini apho indawo ilanga yeyona liphezulu. Ukubala ixesha lawulo ngesekhondi, sebenzisa i "quadratic ixesha", nto leyo ifakwe data evela uququzelelo obume belizwe kwindawo ethile.
