L'attuale ondata di caldo ha fatto schizzare a livelli mai visti prima l'isoterma di zero gradi. Nella notte tra domenica e lunedì, comunica MeteoSvizzera, il limite ha raggiunto infatti la quota di 5'184 metri sul livello del mare, battendo il vecchio record di 5'117 metri, primato che resisteva dal 20 luglio 1995.
È molto raro che l'isoterma di zero gradi salga oltre i 5'000 metri, precisa MeteoSvizzera: le uniche due volte che è successo è stato nelle occasioni sopraccitate. Toccare i 4'900 metri basta già per entrare nella top ten di sempre.
L'isoterma di zero gradi viene determinato dai meteorologi con l'ausilio di palloni sonda, che si alzano due volte al giorno da Payerne.
