L'addio all'inverno e l'arrivo della primavera scattano in Svizzera alle 16.33 di questa domenica. Benché le temperature non siano ancora esattamente miti, è il momento dell'anno che scandisce il passaggio alla bella stagione.
Il tutto, dopo una stagione invernale caratterizzata da un clima non di rado anomalo e, a sud delle Alpi, da una persistente siccità.
Siccità, agricoltori preoccupati

Gli equinozi di primavera e di autunno, in settembre, sono i momenti in cui il centro del disco del Sole si colloca sul punto d'incrocio tra l'equatore celeste e l'eclittica, ossia la traiettoria circolare descritta apparentemente in un anno dal Sole sulla sfera celeste. Il termine equinozio deriva dal latino aequanox (ossia "notte uguale"), a indicare il giorno in cui il dì e la notte hanno la stessa durata.
