Fitowar Wata da Faɗuwarta: me ya sa lokaci ke canzawa kullum

Kusan kowa da ya fara kallon kalandar wata yana mamakin abu ɗaya: lokacin fitowar Wata bai dace da komai ba kuma gobe ya canza. Bambancin ranaku makwabta ƙanƙanta ne — kusan awa ɗaya — amma a wata ana tara kusan cikakkiyar rana, kuma saboda haka sanannen “Wata tana fitowa kusan lokacin faɗuwar rana” yana aiki ne kwanaki kaɗan kusa da cikakken wata. Mu warware daga ina wannan motsi ya fito.

Babban lamba: motsin kullum tabbatacce ne, amma yana canzawa

Lokacin fitowar Wata kullum yana ja baya, watau ya zama makare — in ba haka ba ba zai zagaye da'ira a wata ba. Amma girman wannan ja yana canzawa sau goma sha shida: daga minti 6 zuwa awa 1 minti 37 a ranaku iri ɗaya na shekara.

Bayanin Moscow na Satumba 2026, ba tare da ranaku biyu masu al'amura biyu ba:

Matsakaicin ranaku 36 da aka auna kusan minti 60 ne ga fitowa kuma kusan minti 41 ga faɗuwa. Matsakaicin lambobin biyu yana ba (60 + 41) / 2 ≈ 51 — sanannun ~minti 49 na ƙa'ida ta al'ada; bambanci shi ne cewa waɗannan mintunan na fitowa da faɗuwa sun rabu kusan a sabanin lokaci maimakon a raba su daidai.

Rana tana tafiya daidai: minti biyu a rana, iri ɗaya a duk tebur.

Me ya sa: Wata tana karkata gabas sabanin juyawar sararin sama

Rana ɗaya juyawar sararin sama ce ta 360°, kuma a wannan lokaci Wata tana karkata dangane da taurari kusan digiri 13 zuwa gabas. Gabas kishiyar shugaban juyawar yau da kullum na sararin sama ce, don haka Wata kullum tana fitowa a makare.

Motsin da ke aiki a nan shi ne juyawar sararin sama zuwa yamma, yayin da Wata ke karkata zuwa gabas. Motsi biyu ne masu gaba da juna, kuma daga bambancinsu aka haifi ja na yau da kullum.

Girman ja yana canzawa saboda kusurwa tsakanin hanyar rana da sararin sama tana canzawa a shekara. A farkon Satumba a sararin safiya hanyar rana tana hawa da tsini kuma Wata tana ketare sararin da sauri, don haka ja yana da girma. A wani lokaci na shekara kuma a wasu sassan sararin ta kwanta lami kuma ja ya ragu zuwa mafi ƙanƙanta. Don haka kololuwa da kwari suna faɗuwa a tsakiyar wata ba a gefenta ba.

Rana tana da motsin kanta a sararin sama — kusan digiri ɗaya a rana zuwa gabas — don haka fitowarta tana motsa cikakkiyar rana a shekara. Haɗin wannan motsi, karkatar hanyar rana, matsakaicin kewayawa da latitud na birni ne ke ba minti biyu a rana. Ba za a iya mayar da shi ga abu ɗaya ba: duka huɗu suna aiki.

A cikin wata ana tara cikakkiyar rana

Irin wannan lissafi ga faɗuwa ma gaskiya ne — don haka matsakaicin minti 50 sun faɗo a kan kowane ɗayan lokuta biyu ba a raba su rabi ba.

Dangantaka da ranar wata da lokacin farawa

A ginshiƙin “Farawar rana” na babban kalanda lokacin farawar ranar wata ne. Ya kusan daidaita da lokacin fitowar Wata, kuma ba daidaituwa ba ne: ranakun wata a tarihi ana ƙirgawa daga fitowa.

A aikace wannan yana nufin lokacin farawar ranar wata bai daidaita da lokacin fitowa ba — ko da yana tafiya daidai wannan gudu.

Latitud yana canza hoto

Duk abin da aka faɗa gaskiya ne ga kowace latitud, amma girman bambanci ya dogara da latitud sosai.

A matsakaicin latitud faɗin lokacin fitowa a wata cikakkiyar rana ne, kuma Wata tana samuwa a lokuta daban na yini ba tare da dogon hutu ba. A manyan latitud a hunturu bambancin ƙimar ƙarshe ta kai awa da yawa, kuma a yankunan polar akwai ranaku da Wata ba ta fitowa ko faɗuwa.

Sakamakon aiki: shawara “Wata da yamma ta fi kyau a gani” ta shafi matsakaicin latitud kuma ta daina aiki a hunturu a arewa. Idan kana shirya kallo a manyan latitud, ka bi teburin fitowa da faɗuwa, ba al'ada ba.

Yadda ake amfani da waɗannan bayanai

Ƙarshe biyu masu amfani daga teburin sama.

Na farko: farkon rabi shi ne babban abin yamma. Yana fitowa kusan tsaka, yana tsaye a ɓangaren kudancin sararin lokacin faɗuwar rana kuma yana faɗuwa kusan tsakiyar dare, watau ya mamaye dukan yamma. Don kallo bayan tsakiyar dare ana buƙatar cikakken wata da ƙarshen rabi. Amma a sabon wata Wata da gaske ba ta bayyana a sararin dare: tana fitowa da faɗuwa tare da Rana.

Na biyu: idan kana jiran Wata wani dare, ka duba teburin faɗuwa, ba na fitowa ba. Don kallon yamma muhimmanci shi ne Wata za ta faɗu yaushe; don kallon dare ana buƙatar yaushe za ta fito da yaushe za ta faɗu, watau cikakken tazara.
