SANTA ANA WINDS

Santa Ana Winds may refer to: 1. Santa Ana wind, a local Southern California reference to Föhn winds, a meteorological phenomenon occurring as a layer of wind is forced over a mountain range -- drying the air -- which then passes over the crest and begins to move downslope -- heating -- and becoming a strong, gusty, warm and dry wind which can raise temperatures as much as 30°C (54°F) in a few hours. The risk of fire danger increases by the winds' warm and dry conditions.
