Beijing will use artificial rainmaking to clear the air after a choking dust storm coated China’s capital and beyond with yellow grit, prompting a health warning to keep children indoors, state media said Tuesday.
The huge storm blew dust far beyond China’s borders, blanketing South Korea and reaching Tokyo.
The storm, reportedly the worst in at least five years, hit Beijing overnight Sunday, turning the sky yellow and forcing residents to dust off and hose down cars and buildings.
