Definition
Noun: A fohn is a warm, dry wind that descends on the northern side of a mountain range, especially the Alps, after losing its moisture on the southern slopes. This wind can cause a rapid increase in temperature.
Usage
The word "fohn" is a specific meteorological term. It is used to describe a particular type of wind with distinct characteristics (warm and dry) and a specific geographic association (the Alps). It is often used in weather reports, geographical descriptions, and scientific discussions about mountain climates.
Examples
- The sudden thaw was caused by a strong fohn wind blowing from the south.
- Skiers often appreciate the fohn for the pleasant weather it brings, despite it sometimes causing avalanche conditions.

Advanced Usage

- Föhn effect / Foehn effect: This describes the broader meteorological process that creates fohn winds, involving the adiabatic warming of air as it descends.
