China dust cloud circles the globe

Dust clouds generated by a huge dust storm in China’s

Taklimakan desert in 2007 made more than one full

circle around the globe in just 13 days, a Japanese

study using a NASA satellite has found. According to a

Reuters report, dust clouds were formed on 8-9 May

2007 in the deserts of Xinjiang. They were then lifted

8-10km above the earth’s surface, and transported

more than one full circle around the earth. The

entire dust cloud measured about 3km vertically and

up to 2,000km horizontally and stayed that way even

after one full trip around the globe.
