Mike Olbinski’s latest storm chasing timelapse, “Monsoon V,” is once again spectacular. Although I do think the name could have been “Haboob” instead, given how many sweeping dust clouds encroach on the viewer. These towering wall clouds of dust can form from downdrafts at the leading edge of a cold front, or from the fading remains of a thunderstorm. In dry, dusty regions like Arizona, the strong downward winds spread outward as they near the ground, picking up dust and sand. Below you can see two examples of haboobs racing ahead of fronts. 

The middle image shows a microburst, where a sudden, localized downdraft falls out of the storm. Notice how the wind and rain sweep outward as they near the ground. This is typical of any flow heading straight toward a wall! Check out the full video for lots more gorgeous fluid dynamics in action. (Video and image credit: M. Olbinski)
