Definition
- Noun:
- A warm, dry wind that descends the leeward side of a mountain range: A foehn is a specific type of wind characterized by its warmth and dryness, which occurs as air descends after crossing a mountain barrier. This process causes the air to warm adiabatically (by compression), often leading to a rapid temperature rise and a drop in humidity on the downwind side.
Examples of Usage
- Noun:
- The sudden warm foehn melted the snow on the valley floor.
- Meteorologists issued a warning for strong foehn winds in the alpine regions.
- The characteristic dryness of the foehn can increase the risk of wildfires.
Advanced Usage
- "Foehn effect" or "Foehn phenomenon": The meteorological process that creates a foehn wind.
