Physics of desert dust walls, history of the haboob
ASU weather expert Randy Cerveny talks about the history and effects of haboobs.
The dust wall that hit Phoenix on July 5, was more than a mile high and some 50 miles wide. Before it was over, Sky Harbor International Airport was closed down, driving was hazardous and severe storm warnings were out for much of Central and Western Arizona.
It was the largest dust storm in the area in several decades.
