A low-pressure system (click here) brought strong winds—gusting to 55 miles (85 kilometers) per hour—to the Southern Plains on March 18, 2014. The winds picked up exposed soil from the parched landscape, resulting in a large dust storm that covered parts of Colorado, Kansas, Oklahoma, New Mexico, and Texas.

The differences in color are due to changes in lighting.
The dust in this image originated in New Mexico. The plume stretched across about 175 kilometers (110 miles) in the top image, but was somewhat dissipated a couple of hours later. The large images show dust across a wider area, including a second large dust plume in southern Colorado, Kansas, and Oklahoma....
