Dust in Bodélé Depression Blows Southwest Towards Lake Chad13.3N 14.1E
The Bodélé Depression, located at the southern edge of the Sahara Desert in north central Africa, is a place where dust storms occur on average about 100 days per year. Here, some dust can be seen blowing towards the southwest, towards Lake Chad.
Recent research has indicated that storms move across the Bodélé Depression at about 47 km/h (29 mi/h)—two times faster than previously believed. The research also found that winds have to whip across the region at a minimum of 36 km/h (22 mi/h), to kick up a dust storm. The pattern of air flow is so common that the winds have scoured a straight path in the ground, marking its southwesterly flow, as can be observed here.
