Kusayensi yezinkanyezi, a syzygy Kwenzeka lapho izindikimba zasezulwini ezimbili noma ngaphezulu ziqondana emgqeni oqondile, noMhlaba nawo umi eduze kwalo mugqa. Lisetshenziswa kusayensi yezinkanyezi kanye nesayensi yokwakheka komhlaba ukuchaza ukuhleleka okuthile noma ukuhlelwa kwezinto ezintathu noma ngaphezulu ezisemkhathini, njengamaplanethi, izinyanga, noma izinkanyezi. Lesi simo senzeka lapho lezi zinto zisemugqeni oqondile noma ekucushweni okuthile kwejiyomethri okuhlobene nomuntu obukele eMhlabeni.
Kulesi sihloko sizokutshela konke okudingeka ukwazi mayelana nokuthi iyini i-syzygy, ukuthi yenzeka nini nokuthi imiphi imiphumela enayo.
Yini
Lesi simo singabonwa eMhlabeni ngezindlela ezimbili eziyinhloko:
- Uma iNyanga neLanga kubekwe ezinhlangothini ezihlukene zomhlaba, lokhu kubizwa ngokuthi ukuphikiswa.
- Ezenzakalweni zasezulwini, lapho inyanga nelanga zifinyelela iphuzu lokuhlangana, ukusondelana kwazo esibhakabhakeni kuba sobala.
I-Syzygy ibhekisela ekuqondaneni kwezindikimba zasemkhathini ngendlela eqondile. Lokhu kuqondanisa kungathatha isimo sokusitheka kwelanga, ukubhula, noma ukuthutha. I-eclipse isenzakalo esenzeka lapho indikimba yasezulwini isithwe, ngokuphelele noma ingxenye, ngokulumba, noma lapho idlula ethunzini lenye indikimba yasezulwini. Ukuvala kwenzeka uma into enkulu ihamba phambi kwencanyana, iyivimbe ukuthi ingabonakali.
Isenzakalo sezokuthutha senzeka lapho indikimba encane yasezulwini idlula ngaphambi kwenkulu. Njengoba umzimba omncane uhlala uzungeza phambi komkhulu, Lo mcimbi waziwa ngokuthi yi-eclipse yesibili.
I-Syzygies iyimicimbi ethokozisayo futhi ivame ukugqanyiswa kusayensi yezinkanyezi ngoba ingathinta amagagasi noma ibangele ukusitheka kwelanga. Isibonelo, ngesikhathi se-lunar syzygy, Umhlaba, Inyanga, kanye neLanga kuyahambisana, okuholela ekusithekeni kwenyanga noma kwelanga, kuye ngokuthi iNyanga iyadlula emthunzini womhlaba noma iNyanga ingena phakathi komthunzi.Umhlaba kanye neLanga. Ukwengeza, ama-syzygies angathonya amagagasi ngenxa yamandla adonsela phansi ahlanganisiwe ezinto eziqondanisiwe, okungase kubangele amagagasi aphezulu noma aphansi kunokuvamile, aziwa ngokuthi ama-syzygy tides.
I-Syzygia nama-spring tides
I-Syzygy inomthelela oqondile kulokho okwaziwa ngokuthi "ama-spring tides." Amagagasi asentwasahlobo amagagasi aphezulu ikakhulukazi avela ngezikhathi zenyanga entsha nenyanga egcwele, lapho uMhlaba, iNyanga kanye neLanga kuhambisana ngendlela ehambisanayo.
Inyanga neLanga zisebenzisa amandla adonsela phansi eMhlabeni ngenxa yobuningi bazo. Inyanga, ngenxa yokuba seduze noMhlaba, inomthelela omkhulu kakhulu emazingeni olwandle kuneLanga.Kodwa-ke, uma iqondaniswe ngendlela ene-syzygy, amandla ayo adonsela phansi ayahlangana, okusho ukuthi amandla adonsela phansi eNyanga kanye neLanga Umhlaba unamandla.
Ngesikhathi senyanga entsha noma inyanga egcwele i-syzygy, Umhlaba, Inyanga kanye neLanga ziqondana ngomugqa oqondile. Ngalesi sikhathi, amandla adonsela phansi eNyanga kanye neLanga ayahlangana, okuholela ekudonseni okukhulu kwamandla adonsela phansi ohlangothini loMhlaba oluseduze neNyanga futhi ngakolunye uhlangothi loMhlaba, maqondana neLanga.
Ukudonsa okwengeziwe kwamandla adonsela phansi kubangela ukungqubuzana esimweni soMhlaba, kudala “amaqhuqhuva” amabili olwandle: enye ibheke eNyangeni enye ibheke ngaseLangeni. Lezi zigaxa zamanzi zinesibopho samagagasi aphezulu ngesikhathi se-syzygies.
Amagagasi aphumela ngesikhathi, nethonya elihlangene leNyanga neLanga, aziwa ngokuthi "amagagasi entwasahlobo." Lawa magagasi entwasahlobo aphakeme ngokuphawulekayo kunamagagasi avamile, avela ngezinye izikhathi zenyanga lapho iNyanga neLanga zingahambelani ku-syzygy.
Iziphi izikhathi lapho amaplanethi e-syzygies enzeka?
I-Planet syzygies iyenzeka lapho amaplanethi eqondana ngesikhathi sokuhlangana noma ukuphikiswa. Mayelana nezibalo zamaplanethi, u-Jan Meeus, isazi sezinkanyezi esidumile saseBelgium kanye nombhali oyinhloko wama-algorithms amaningi okubala amaplanethi asetshenziswayo njengamanje, eyethulwe emsebenzini ka-1977 ukuphindaphinda kwezenzakalo zezinkanyezi zalolu hlobo.
Ngo-December 30, 1591, iplanethi ekhanyayo yasebenza okokugcina phakathi nokusitheka kwenyanga ngokuphelele. Lesi senzakalo senzeka lapho iSaturn isithwe yinyanga. Ngaphezu kwalokho, ukuhleleka kwamaplanethi ayisishiyagalolunye abonakalayo ngo-1982 kwakuwumbukwane ophawuleka ngempela.
Izenzakalo ezizayo zezinkanyezi lapho iNyanga izosithwa khona kanye namanye amaplanethi zibizwa ngokuthi ama-syzygies. I-syzygies elandelayo ingabonwa ngonyaka ka-2344, kusukela enyakatho ye-hemisphere yeSaturn. Ngo-2488, zizobonakala zisuka e-Antarctica lapho inyanga izosithwa yi-Mars. Enye i-syzygy ingabonwa ngonyaka ka-2932, lapho iNyanga izosithwa yi-Jupiter futhi izobonakala ezindaweni ezisenkabazwe.
Ubude besikhathi samagagasi
Amagagasi entwasahlobo ngenxa ye-syzygy awekho ngosuku olulodwa, kodwa kunalokho alandela umjikelezo wanyanga zonke ohambisana nezigaba zenyanga. Isikhathi esilinganiselwe phakathi kwama-syzygies amabili alandelanayo cishe izinsuku eziyi-14, okuyingxenye yomjikelezo ophelele wenyanga, owaziwa ngokuthi yinyanga yesinodi noma inyanga yenyanga. Lo mjikelezo wenyanga ye-synodic isikhathi esithathayo ukuze iNyanga ibuyele esigabeni esifanayo (isibonelo, kusukela enyangeni ethwasa kuya enyangeni entsha).
Nansi indlela umjikelezo osebenza ngayo:
- Inyanga entsha: Umjikelezo uqala nge-syzygy lapho iNyanga, Umhlaba kanye neLanga kuhambisana khona. Kuleli qophelo, amagagasi entwasahlobo ayenzeka, namagagasi aphezulu kakhulu.
- Ikota yokuqala: Njengoba iNyanga iqhubekela phambili emzileni wayo ozungeza Umhlaba, ihamba phakathi kwezigaba ze-crescent kanye ne-crescent gibbous. Ngalesi sikhathi, amandla adonsela phansi eNyanga neLanga aqala ukwehlukana, okuholela ekwehleni kancane kancane kokuphakama kwamagagasi.
- Inyanga egcwele: Khona-ke, ngemva kwesikhathi esingangesonto kusukela ku-syzygy yokuqala, i-syzygy entsha ifinyelelwa esigabeni senyanga egcwele. Kuleli qophelo, amagagasi entwasahlobo asephezulu futhi.
- ikota yokugcina: Njengoba iNyanga iqhubeka nokuthuthuka emzileni wayo, idlula esigabeni sokuqala nesigaba sokugcina se-gibbous. Ngalesi sikhathi, amandla adonsela phansi eNyanga kanye neLanga ayaqhubeka nokuncipha, futhi amagagasi ayancipha kancane kancane futhi.
- Buyela enyangeni entsha: Ekugcineni, ngemva kwesinye isikhathi esingangesonto, iNyanga ibuyela esigabeni sokuthwasa kwenyanga bese kuba ne-syzygy entsha. Amagagasi entwasahlobo aphinde aphezulu futhi umjikelezo omusha uqala.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana ne-syzygy nezici zayo.
