The term 'Warm Alpine Wind' can be broken down into two crossword solutions: Foehn (5 letters) and Fohn (4 letters). Foehn is a warm, dry wind that originates in the mountains and descends to the valleys below. It is also known as a 'snow-eater' because it melts snow quickly. Fohn is a similar wind, but it is slightly cooler and more humid than Foehn. Both winds are common in the Alps and other mountain ranges, and they can cause significant weather changes in the areas they affect.
