Schnee und Nordstaulagen: Wo in den Alpen der meiste Schnee fällt

Nordstaulagen sind für die Schneemengen in den Alpen von entscheidender Bedeutung. Diese Wetterlagen treten auf, wenn feuchte Luftmassen aus nördlicher Richtung auf die Alpen treffen, wo sie aufsteigen und abkühlen. Dies führt zu starken Schneefällen, besonders in Tälern und Skigebieten auf der Nordseite der Alpen. Die geografische Lage, Höhe und Ausrichtung spielen dabei eine wesentliche […]
