聖塔安那風

圣塔安娜风是一种典型的南加州季节性强风。圣塔安娜风是强烈且非常干燥的下坡风，起源于内陆，影响到沿海的南加利福尼亞州和北下加利福尼亚半岛。該風經常引起在加州的森林大火。[1][2]

聖安娜風從沙漠中橫掃，沿著加利福尼亞南部沿海，將野火焚燒成灰塵和煙霧帶到遠處太平洋上。 洛杉磯在這張圖片的左上方，聖地亞哥靠近中心。

This map illustration shows a characteristic high-pressure area centered over the Great Basin, with the clockwise anticyclone wind flow out of the high-pressure center giving rise to a Santa Ana wind event as the airmass flows through the passes and canyons of southern California, manifesting as a dry northeasterly wind.

"(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."
