From Wikipedia, the free encyclopedia
A Sundowner is an offshore wind which occurs when a region of high pressure is directly north of the Santa Barbara area, the part of the California coast which trends east-west. When the pressure gradient is perpendicular to the axis of the Santa Ynez Mountains, which rise directly behind Santa Barbara, the winds blow with greatest force. These winds often precede Santa Ana events by a day or two, as it is normal for high pressure areas to migrate east, causing the pressure gradients to shift to the northeast.[1]
