Sandstorms, high winds prompt Beijing to cancel hundreds of flights and close parks

"High winds and the threat of sandstorms prompted Beijing to cancel hundreds of flights and

close public parks, as massive gales felled hundreds of trees, crushing cars and damaging older homes across China's capital.
Beijing's two massive international airports, Beijing Capital and Daxing, canceled 693 flights by 2 p.m. local time, with warnings of more violent weather on its way, especially in the country's north and along coastal areas.
More flights and trains were canceled in other parts of China. Some parts of the country recorded their most powerful winds in more than 75 years, registering at up to 92 mph.
Weather agencies in China blamed the poor air quality on a sandstorm sweeping across northern China from northern Mongolia, where authorities there said it had left several dead, before being carried south by winds." CBS
