Industrieschnee unter dem Nebel: Schneefall unten, Traumwetter oben?

Kann es wirklich sein, dass unter einer dichten Nebeldecke Industrieschnee fällt, während darüber strahlend blauer Himmel herrscht? Dieses aussergewöhnliche Phänomen, bei dem unten winterliche Schneeverhältnisse herrschen und oben traumhaftes Wetter genossen wird, ist meteorologisch gut erklärbar. Wir tauchen in die spannende Welt des Industrieschnees ein und klären, wie solche Kontraste entstehen. Was ist Industrieschnee? Industrieschnee […]
