Dusty Skies over Southern California

April 2, 2003
Southern California's "Santa Anas" are dry, north-easterly winds having speeds in excess of 25 knots (46 kilometers/hour). These offshore winds usually occur in late fall and winter when a high pressure system forms in the Great Basin between the Sierra Nevadas and the Rocky Mountains. This view from the Multi-angle Imaging SpectroRadiometer shows the pattern of airborne dust stirred up by Santa Ana winds on February 9, 2002.
