Potrivit Observatorului Astronomic “Amiral Vasile Urseanu”, dup\u0103 “M\u0103r\u021bi\u0219or”, “Babe” \u0219i “Mo\u015fi”, dup\u0103 “z\u0103pada mieilor”, c\u00e2nd calendaristic deja am p\u0103\u0219it \u00een anotimpul prim\u0103verii, de\u0219i luna martie se dovede\u0219te a fi destul de capricioas\u0103, ne apropiem de momentul echinoc\u021biului de prim\u0103var\u0103, ce marcheaz\u0103 \u00eenceputul prim\u0103verii astronomice.<\/p>\n\n\n\n

El se produce \u00een jurul datei de 20 martie c\u00e2nd longitudinea astronomic\u0103 a acestuia revine la valoarea de zero grade.<\/p>\n\n\n\n

“Dup\u0103 cum este cunoscut, mi\u0219carea aparent\u0103 a Soarelui pe sfera cereasc\u0103, determinat\u0103 de mi\u0219carea real\u0103 a P\u0103m\u00e2ntului pe orbita sa, genereaz\u0103 pentru latitudinile noastre inegalitatea duratei zilelor \u0219i nop\u021bilor la diferite epoci ale anului, datorit\u0103 pozi\u021biei aproximativ fixe \u00een spatiu a axei de rota\u021bie a P\u0103m\u00e2ntului, precum \u0219i a \u00eenclin\u0103rii sale fa\u021b\u0103 de planul orbitei acestuia. Astfel, pe sfera cereasc\u0103, Soarele parcurge \u00een decurs de un an un cerc mare numit ecliptica (ce marcheaz\u0103 de fapt planul orbitei P\u0103m\u00e2ntului), care face cu ecuatorul ceresc un unghi de 23\u00b0 27\u2032 “, arat\u0103 Observatorul Astronomic “Amiral Vasile Urseanu”.<\/p>\n\n\n\n

La momentul echinoc\u021biului de prim\u0103vara Soarele traverseaz\u0103 ecuatorul ceresc trec\u00e2nd din emisfera austral\u0103 a sferei cere\u0219ti \u00een cea boreal\u0103.<\/p>\n\n\n\n

C\u00e2nd Soarele se afl\u0103 \u00een acest punct, numit punct vernal, el descrie mi\u0219carea diurn\u0103 \u00een lungul ecuatorului ceresc, fenomen ce determin\u0103, la data respectiv\u0103, egalitatea duratei zilelor cu cea a nop\u021bilor, indiferent de latitudine.<\/p>\n\n\n\n

La latitudinile Rom\u00e2niei, pentru care se consider\u0103 valoarea medie de 45\u00b0, aceast\u0103 cifr\u0103 reprezint\u0103 \u0219i valoarea medie a \u00een\u0103l\u021bimii Soarelui deasupra orizontului la momentul amiezii. Totodat\u0103, la data respectiv\u0103, Soarele r\u0103sare \u00een punctul cardinal est \u0219i apune \u00een punctul cardinal vest.<\/p>\n\n\n\n

\u00cencep\u00e2nd de la aceasta dat\u0103, durata zilei (fa\u021b\u0103 de cea a nop\u021bii) va fi \u00een continu\u0103 cre\u0219tere, iar cea a nop\u021bii (fa\u021b\u0103 de cea a zilei) \u00een sc\u0103dere, p\u00e2n\u0103 la data de 21 iunie, c\u00e2nd va avea loc momentul solsti\u021biului de var\u0103.<\/p>\n\n\n\n
