Fohn (Föhn) wind

Warm and dry winds descending on the leeward side of the mountain. The air falling to the floor of an adjacent valley or plain after blowing across the mountaintop warms up adiabatically. Thus, this wind is warmer than the surrounding air. In Europe, it is known as a Fohn or Föhn wind. In the United States and Canada, along the eastern slopes of the Rockies (i.e., leeward side), the Indian name Chinook is used.
i. A form of metal rolled into a very thin sheet with a thickness less than 0.006 in (0.15 mm).
