Q211: What weather is typically experienced during Foehn conditions in the Bavarian area near the Alps? ^t50q211

• A) Cold, humid downslope wind on the lee side, flat pressure pattern
• B) High pressure over Biscay with a low pressure area in Eastern Europe
• C) Nimbostratus on the northern Alps, rotor clouds on the windward side, warm dry wind
• D) Nimbostratus on the southern Alps, rotor clouds on the lee side, warm dry wind

Correct: D)

Explanation: During South Foehn in the Bavarian pre-alpine region, moist Mediterranean air is driven northward against the Alps. Nimbostratus develops on the southern (windward, Italian) slopes with heavy orographic precipitation. As the air crosses the ridge and descends on the northern (lee, Bavarian) side, it warms adiabatically and arrives as a characteristically warm, dry wind. Rotor clouds and lenticular clouds form in the lee-side standing waves. Option A wrongly describes the Foehn wind as cold and humid — it is warm and dry on the lee side. Option B describes only the synoptic setup without the actual weather. Option C incorrectly places the Nimbostratus on the northern (lee) side and the rotor on the windward side.
