Mafunde apakati

Mafunde, zodabwitsazi zomwe zimapangitsa gombe nthawi zina kukhala zokulirapo komanso nthawi zina kukhala zazing'ono. Uku ndikusuntha kwakanthawi kwamadzi ambiri chifukwa cha kukopa komwe kumachitika ndi mwezi ndi dzuwa Padziko Lapansi. Mukamayankhula za mafunde, mumamva mafunde amoyo komanso osasunthika. Kodi chilichonse ndi chiyani ndipo kukhalapo kwake kumadalira chiyani?

Ngati muli ndi chidwi ndi zonsezi, apa mupeza zambiri zamomwe mafunde amagwirira ntchito, mafunde apasupe ndi mitundu yanji. Kodi mukufuna kupitiliza kuwerenga? 🙂

Mafunde ndi kuzungulira kwake

Mwezi ndi Dzuwa zimakhala ndi mphamvu yokoka padziko lapansi yomwe imapangitsa kuti madzi ambiri aziyenda mosadukiza. Nthawi zina mphamvu yokoka imagwira ntchito limodzi ndi inertia yomwe imapangidwa ndi kuyenda kwa dziko lapansi ndipo mafunde amawonekera kwambiri. Chifukwa cha kuyandikira kwa mwezi polemekeza dziko lathu lapansi, zomwe zimachitika pamadzi ambiri ndizapamwamba kuposa za Dzuwa.

Dziko limayenda palokha maola 24 aliwonse. Tikaimirira kunja, titha kuwona momwe dziko lathu ndi mwezi zimayendera kamodzi patsiku. Izi zingawonetse kuti pamakhala mafunde ozungulira amodzi maola 24 aliwonse. Komabe, amapangidwa mozungulira pafupifupi maola 12. Chifukwa chiyani izi zikuchitika?

Mwezi ukakhala m'mbali mwa nyanja, umakopa madziwo ndipo amatuluka. Izi ndichifukwa choti Dziko Lapansi ndi mwezi zimapanga dongosolo lomwe limazungulira pakatikati pa kasinthasintha. Izi zikachitika, mbali ina ya Dziko lapansi kayendetsedwe kake kamachitika, ndikupangitsa mphamvu ya centrifugal. Mphamvu iyi Imatha kupangitsa madzi kukwera ndikupangitsa zomwe timazitcha kuti mafunde apamwamba. Mosiyana ndi izi, nkhope za dziko lapansi moyang'anizana ndi mwezi zomwe sizimakhudzidwa ndi mphamvu yokoka sizikhala ndi mafunde ochepa.

Mafunde samakhala ofanana nthawi zonse chifukwa pali zinthu zina zomwe zimatsimikizira kukula kwake. Ngakhale zimadziwika kuti kuzungulira pakati pamafunde otsika ndi okwera ndi maola 6, kwenikweni sizili choncho kwenikweni. Dziko lapansi silinapangidwe ndi madzi okha. Ndikuti pali makontinenti, ma geometri a m'mbali mwa nyanja, mbiri yakuya, mikuntho, mafunde am'nyanja ndi mphepo zomwe zimakhudza mafunde.

Mafunde amoyo komanso osalala

Monga tatha kunenera, mafundewo amadalira komwe kuli mwezi ndi Dzuwa. Pamene izi zikugwirizana ndi dziko lapansi, mphamvu yokopa yokoka imakhala yayikulu. Izi zimachitika tikakhala mwezi wathunthu kapena watsopano. Izi zimapangitsa kuti mafunde akhale okwera kwambiri ndipo amatchedwa mafunde apamadzi.

Kumbali inayi, pamene mwezi, Dziko lapansi ndi dzuwa zimapanga ngodya yolondola, mphamvu yokoka imakhala yochepa. Mwanjira imeneyi amadziwika kuti mafunde oyenda bwino. Izi zimachitika nthawi yakulowa ndi kutha.

Kuti timveketse bwino mfundo zonsezi, tisiya matanthauzidwe ena omwe ndi othandiza kwambiri:

• Mafunde apamwamba kapena mafunde apamwamba: Madzi am'nyanja akafika pamlingo wokwanira pamafunde.
• Mafunde otsika kapena mafunde otsika: Madzi akamayenda pamafunde amafika pamlingo wochepa kwambiri.
• Mkulu mafunde nthawi: Nthawi yomwe mafunde okwera kapena mphindi yayikulu yamatalikidwe am'nyanja imachitika nthawi ina.
• Nthawi yamafunde otsika: Nthawi yomwe mafunde otsika kapena matalikidwe apansi pamadzi amachitika nthawi inayake.
• Kutulutsa: Ndi nthawi yapakati pa mafunde akuya ndi mafunde ochepa.
• Kukula: Nthawi pakati pamafunde otsika ndi mafunde akuya

Mitundu yamafunde amasika

Pali zosintha zambiri zomwe zimachita mafundewo, chifukwa chake, pali mitundu ingapo.

Mafunde apakati

Amadziwika kuti syzygies. Ndiwo mafunde wamba amasika, ndiye kuti, omwe amachitika pomwe dziko lapansi, mwezi ndi dzuwa zimagwirizana. Ndipamene mphamvu yokopa imakhala yayitali. Izi zimachitika pakakhala mwezi wathunthu komanso mwezi watsopano.

Mafunde amadzimadzi ofanana

Mafunde amasikawa akachitika, chowonjezera chimodzi chowonjezerapo chimawonjezeredwa. Izi zimachitika nyenyezi zikafanana masiku omwe ali pafupi ndi masika kapena masika. Zimachitika Dzuwa likakhala kwathunthu pa ndege ya dziko lapansi. Poterepa mafunde a kasupe ndi olimba.

Ma equinoctial perigee kasupe wamafunde

Mafunde amtunduwu amachitika pomwe zonse pamwambapa zimachitika, komanso, mwezi uli kumapeto kwake. Apa ndipomwe mafunde okwera amakhala okwera kuposa kale chifukwa cha kuyandikira kwa mwezi ku Dziko lapansi. Komanso, kulumikizidwa kwa mwezi, Dziko lapansi ndi Dzuwa zimakhala ndi mphamvu yokoka. Mafunde a kasupe aka akachitika, magombe omwe akhudzidwa kwambiri amachepetsedwa kupitirira theka.

Chifukwa chiyani kulibe mafunde mu Nyanja ya Mediterranean?

China chake chomwe mwina mukudziwa kale ndikuti mafunde aku Nyanja ya Mediterranean ndi amtengo wapatali. Izi zimachitika chifukwa ndi nyanja pafupifupi yotseka.. Malo ake okha "atsopano" olowera m'madzi ndi kudzera mu Strait of Gibraltar. Popeza gawo lamadzi ili laling'ono, silingathe kuyamwa madzi ambiri kuchokera kunyanja ya Atlantic. Chifukwa chake, madzi ochulukirapo awa amasungidwa panjirayo. Izi zimapangitsa kuti Khwalala liziwoneka ngati mpopi wotsekedwa. Kuphatikiza apo, imapanga polowera mwamphamvu koma osakwanitsa kufikira Mediterranean.

Titha kunena kuti palibe nthawi yokwanira kuti Mediterranean ikhale ndi mafunde. Titha kuyamikiridwa pang'ono munyengo zosankhidwa kwambiri, koma si mafunde amphamvu. Pakutsitsa, zosiyana zimachitika komanso mu Strait kutuluka kwamphamvu kulowera ku Atlantic kumapangidwa.

Tiyeneranso kutchulidwa kuti pokhala nyanja yaying'ono, zokopa za mwezi ndizocheperako. Pali malo ambiri ndi magombe ndipo amangofikira masentimita.

Cabanuelas 2016-2017

Mu 2016 Alfonso Cuenca adaneneratu kasupe wokhala ndi mvula yocheperako kuposa wamba. Kuphatikiza apo, adati kugwa ndi dzinja kudzakhalanso kowuma. Munthawi ya 2017, mvula idakhala yoperewera, kupatula nthawi ya Isitala ndi malo ozungulira.

M'kulosera uku, katswiri wathu cabañuelista sanali kulakwitsa kuyambira 2016 ndi 2017 akhala zaka zowuma kwambiri m'mbiri.

Ndikukhulupirira kuti mutha kumvetsetsa bwino tanthauzo la mafunde am'masika komanso mitundu yake. Tsopano muyenera kuwasanthula kuti agwiritse ntchito zomwe mwaphunzira.
