In a First, Scientists Map Particle-Laden Rivers in the Sky An atmospheric river carrying dust particles blows across the North Atlantic Ocean from Africa to the Caribbean in July 2018.

Animation by climate.gov In Brief: Windy regions high in the atmosphere can transport pollutants like dust or soot thousands of miles around the world and disrupt everyday life for thousands of people. Last summer, “Godzilla” came for the Caribbean and the U.S. Gulf Coast. This particular monster wasn’t of the sci-fi variety, but a massive dust storm kicked up by winds from the Sahara Desert and carried an ocean away. The dust storm was an extreme example of a phenomenon that happens regularly: the global transport of dust, soot, and other airborne particles collectively known as aerosols by jets of winds in the atmosphere, forming what are called aerosol atmospheric rivers.
