聖塔安那風

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。

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北下加利福尼亚半岛。該風經常引起在加州森林大火[1][2]

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.

When the Santa Anas blow, winds can reach exceptional speeds in this narrow gap between the Puente Hills and Santa Ana Mountains."
