圣塔安那风

圣塔安娜风是南加州特有的强烈季节性下坡风，其起源于加州内陆并影响沿海的南加利福尼亚州和北下加利福尼亚半岛，并因极度干燥而经常在加州引起野火。^[1][2]

圣安娜风从沙漠中横扫，沿著加利福尼亚南部沿海，将野火焚烧成灰尘和烟雾带到远处太平洋上。 洛杉矶在这张图片的左上方，圣地亚哥靠近中心。

这张地图插图显示了以大盆地为中心的高气压，顺时针方向的反气旋风从高压中心流出，当气团流经南加利福尼亚的山口和峡谷时，从而产生下降风，形成干燥的东北风，称为圣安娜风。

"(White)Scholars who have looked into the name's origins generally agree that it derives from Santa Ana Canyon, the portal where the Santa Ana River -- as well as a congested Riverside (CA-91) Freeway -- leaves Riverside County and enters Orange County. When the Santa Anas blow, winds can reach exceptional speeds in this narrow gap between the Puente Hills and Santa Ana Mountains."
