[QUOTE="oldslowandugly, post: 1049198, member: 659"] No one in the media seems to understand what the Devil Winds are or why they occur. The first time I heard about them was in Royce's Powerboating Illustrated, 1960, a workbook that was used in safe boating courses. The lesson was about how the Devil Winds can knock down sail boats. Santa Ana was derived form the Indian word Santanta, which means Devil Wind. There are two kinds, and the warm Devil Winds occur during the Spring, Summer, and early Fall. You have a high pressure area on the Nevada plateau to the East, and a low pressure area on the Ocean. The weak Devil Winds flow down through the mountain passes to meet the cool incoming Westerlies. A warm no-wind buffer area sets up between them and gives California it's amazing warm dry weather. It is also responsible for the Temperature Inversions that trap smog over cities like LA. Cold Devil Winds become strong and viscous after Thanksgiving Day as storm tracks move South. The winds pick up velocity as they move through the passes and down the slopes. This compresses and heats the air some 30° while reducing the humidity. The relative humidity in the warm Devil Winds buffer zone can go as low as 10-0%. The wind blows out to sea. This is fire weather. I remember a reporter speaking to an old timer after one of the first major fires. He said there were always brush and forest fires up there in the hills. But nobody lived there. I don't believe 100mph Devil Winds have ever been recorded before. Let's see if this can open and be read: rats, too small. Can anyone enlarge this?
