The Foehn Effect. Also spelled Föhn, this is a hot, dry wind that affects many wine regions. When moist air is pushed towards a mountain, it cools and releases its moisture as rain as it moves up the front, windward side. On the other side (the leeward side), the moisture-less wind warms as it descends, creating hot, dry winds. Beneficial to vineyards for preventing the growth of mold and fungus.
