English: Dust ringed the Taklimakan Desert of northwestern China on April 25, 2010. The light-colored dust is mostly smooth, though waves ripple the surface in the southwest, reflecting turbulence in the air. The low dust also conforms to the shape of the land in the northwest. Squiggly lines in the dust cloud are the clear peaks of the foothills of the Tien Shan mountains, which form the northern edge of the Tarim Basin. Some of the dust appears to be blowing east, perhaps continuing an extensive dust storm from the previous day. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on April 25, 2010.
