NASA MODIS Image of the Day: November 15, 2007 - Dust over Cape Verde
The long, skinny clouds in the upper left corner of the image are wave clouds, probably caused by the same mass of air blowing the dust.
When dry air and moist air meet, the resulting disturbance displaces some air.
Along the tops of these waves of air, clouds form. A similar disturbance appeared in May 2007 over the Arabian Sea.
