Il Foehn delle Alpi Italiane

Abstract

Dapprima vengono esposti e discussi i risultati ottenuti sulla frequenza del Fohn a Torino, Moncalieri e Milano, in base soprattutto alle osservazioni del periodo 1929–44, risultati che confermano come in Piemonte il fenomeno sia piu frequente ed intenso che altrove.—Utilizzando le sole osservazioni al suolo, segue quindi l'analisi di alcuni casi tipici interessanti prevalentemente il Piemonte, poi altri relativi soprattutto alla Lombardia. Le deduzioni principali sono: Il Fohn del versante meridionale delle Alpi si presenta di regola quando sull'Europa domina una situazione barica tipoHW oppure, meno frequentemente, unaNW (secondo Fr.Baur); Determinante per l'inizio del Fohn e la presenza di una depressione secondaria sulla pianura padana od interessante parte di essa; La direzione nettamente prevalente, anche in Lombardia, e quella da NW; Ogni Fohn di non breve durata si manifesta sempre, nel suo primo periodo, con un'aliquota piu o meno marcata di Fohn libero od anticiclonale. A parita di condizioni preesistenti, l'azione termica iniziale e massima per i Fohn associati ad un fronte caldo, mentre quelli con fronte freddo si manifestano soprattutto con una diminuzione dell'umidita; La distribuzione termica verticale in una massa favonica e sempre adiabatica secce o poco scostantesi da questa; L'avanzamento di un fronte caldo da Nord, associato al Fohn, determina spesso onde stazionarie nell'alta troposfera rilevabili (mediante microbarografo) a Sud delle Alpi parecchie ore prima dell'inizio del Fohn.
