Another dust storm moved across eastern China on March 27, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard the Aqua satellite took this picture the same day. In this image, tan dust (in image center), white clouds, and grayish smog mix in the atmosphere over northeastern China.
At least some of the dust might have originated in the Gobi Desert as Gobi dust storms are common in March. Dust storms in March and April can actually exceed the number of storms for all other months combined for that region.
