How do foehn winds affect Upper Bavaria?

In Upper Bavaria, the foehn is a warm, dry wind that descends from the northern Alps onto the Bavarian Plateau.1

These winds affect the region in two notable ways:
* Visibility: They can create an optical phenomenon that makes the Alps visible from locations where they are typically obscured from view.1
* Temperature and Snow: They are responsible for the abrupt melting of snow in the area.1

Generally, a foehn occurs when moist air ascends windward mountain slopes, loses its moisture as precipitation, and then descends the leeward side, warming rapidly through compression.2
