Kuwala kwa dzuwa pa nyengo yachisanu

Nyengo yachisanu, monga gawo lofunikira la mawu 24 adzuwa aku China, ndi tsiku lomwe lili ndi tsiku lalifupi kwambiri komanso usiku wautali kwambiri kudera la kumpoto kwa equator ya Earth.Nyengo yachisanu ndiyo chimake cha ulendo wa kumwera kwa dzuŵa.Patsiku lino, kutalika kwa dzuŵa kumpoto kwa dziko lapansi ndi kochepa kwambiri.Panyengo yachisanu, dzuŵa limaŵala molunjika ku Tropic of Cancer, ndipo dzuŵa limapendekeka kwambiri ku Northern Hemisphere.Nyengo yachisanu ndiyo kusintha kwa ulendo wa kumwera kwa dzuŵa.Pambuyo pa tsikuli, zidzatenga "njira yobwerera".Dzuwa lachindunji limayamba kulowera chakumpoto kuchokera ku Tropic of Cancer (23 ° 26 ′ S), ndipo masiku ku Northern Hemisphere (China ili ku Northern Hemisphere) adzawonjezeka tsiku ndi tsiku.Popeza kuti dziko lapansi lili pafupi ndi perihelion kuzungulira nyengo yachisanu ndipo limayenda mofulumira pang’ono, nthaŵi imene dzuŵa limaŵala mwachindunji kum’mwera kwa dziko lapansi ndi lalifupi ndi masiku 8 kuposa nthaŵi imene limawalira mwachindunji kumpoto kwa dziko lapansi m’chaka chimodzi. , kotero kuti nyengo yachisanu kumpoto kwa dziko lapansi imakhala yaifupi pang’ono kuposa chilimwe.

Kusintha kwanyengo

Panyengo yachilimwe, anyamata atatu anabisala, ndipo m’nyengo yozizira, amuna asanu ndi anayi anawerengedwa.

Pambuyo pa nyengo yachisanu, ngakhale kuti kutalika kwa dzuwa kunakwera pang'onopang'ono, inali njira yochepetsera kuchira.Kutentha komwe kunatayika tsiku ndi tsiku kunali kochuluka kuposa kutentha komwe kunalandira, kusonyeza mkhalidwe wa "kukhala mopitirira malire athu".Mu "masiku 39, 49", kutentha kumakhala kochepa kwambiri, kutentha kumakhala kochepa kwambiri, ndipo nyengo ikuzizira kwambiri.China ili ndi gawo lalikulu, lokhala ndi kusiyana kwakukulu kwa nyengo ndi malo.Ngakhale kuti masiku a nyengo yachisanu ndi aafupi, kutentha kwa nyengo yachisanu sikotsika kwambiri;Sikudzakhala kozizira kwambiri nyengo yachisanu isanayambe, chifukwa pamakhalabe "kutentha kwakukulu" pamwamba, ndipo nyengo yozizira kwenikweni itatha nyengo yachisanu.Chifukwa cha kusiyana kwakukulu kwa nyengo ku China, nyengo ya zakuthamboyi mwachiwonekere yachedwa kumadera ambiri a China.

Pambuyo pa nyengo yachisanu, nyengo m'madera onse a China idzalowa m'malo ozizira kwambiri, ndiko kuti, anthu nthawi zambiri amati "kulowa m'masiku asanu ndi anayi" ndi "masiku angapo ozizira".Zomwe zimatchedwa "kuwerengera zisanu ndi zinayi" zimatanthawuza kuwerengera kuyambira nthawi yachisanu mpaka tsiku lokumana ndi amayi (amanenedwanso kuti kuwerengera kuyambira nyengo yachisanu), ndikuwerengera masiku asanu ndi anayi aliwonse monga "zisanu ndi zinayi", ndi zina zotero;Kuwerengera mpaka masiku "makumi asanu ndi anayi mphambu asanu ndi anayi" makumi asanu ndi atatu ndi limodzi, "maluwa asanu ndi anayi a pichesi akuphuka", panthawiyi, kuzizira kwapita.Masiku asanu ndi anayi ndi gawo, lomwe limatchedwa "naini".Pambuyo pa zisanu ndi zinayi, masiku 81 ndendende, ndi "zisanu ndi zinayi" kapena "zisanu ndi zinayi".Kuyambira "19" mpaka "99", nyengo yozizira imakhala yofunda.

Phenological phenomenon

Mabuku ena akale a ku China amagaŵa nyengo yachisanu m’zigawo zitatu: “siteji imodzi ndi mfundo ya nyongolotsi za m’nthaka, siteji yachiwiri ndi kuthyoka kwa nyanga ya mbira, ndipo gawo lachitatu ndi kusuntha kwa kasupe wa madzi.”Zikutanthauza kuti nyongolotsi ya m’nthaka ikungopindikabe, ndipo mbozi imamva kuti yin qi ikucheperachepera ndipo nyangayo ikusweka.Nyengo yachisanu ikatha, kuwala kwa dzuwa kumabwerera kumpoto, ndipo ulendo wopita ndi dzuŵa umalowa m’njira yatsopano.Kuyambira pamenepo, kutalika kwa dzuwa kumakwera ndipo tsiku limakula tsiku ndi tsiku, kotero kuti madzi akasupe m'phiri amatha kuyenda ndi kutentha panthawiyi.
