Copyright © 2022, Los Angeles Times | | | | Advertisement Santa Ana winds are strong, dry downslope winds in Southern California and northern Baja California. They’re caused by clockwise circulation around areas of surface high pressure east of the Sierra Nevada in the Great Basin region.

As the air sinks, it is compressed and warms. It also loses moisture,...…Copyright © 2022, Los Angeles Times | | | | Advertisement Santa Ana winds are strong, dry downslope winds in Southern California and northern Baja California.
