Texan Haboob This is a true “Haboob” viewed out the window of an aircraft at 38,000 feet or so, formed over Texas in 2014. A haboob is a “density current”. If enough dust lofts into the air, that mixture of air and dust will be denser than the atmosphere above it. The dense layer will hug close to the ground, blowing along with whatever winds are driving it and creating a wall of dust like this one. -JBB Image credit: Ryan Scott of Dallas Texas (shared with permission): https://twitter.com/RaiderTex52/status/443764260800196608/photo/1
