North China Experienced Sand And Dust Weather
BEIJING, CHINA - MARCH 18: (CHINA OUT) A policeman patrols on the Tiananmen Square as floating dust changed color of the sky to orange on March 18, 2008 in Beijing, China. The blowing sand and floating dust weather hit regions in northern China today with visibility in some areas less than 3 kilometers. Sandstorms plagued Beijing and many other cities in north and northwest China every spring mainly due to desertification. China on March 12 announced new measures to control dust ahead of this year's Olympic Games in Beijing, promising clean air for athletes. (Photo by China Photos/Getty Images)
