Scientists 'cause' Beijing snow

Chinese meteorologists say they brought about Beijing's earliest snowfall in a decade, after seeding rain clouds with silver iodide to ease a drought.

The Weather Modification Office sprayed clouds with 186 doses of the chemical to bring rain for the wheat crop.



But the arrival of a cold front caused heavy snow to fall, disrupting road, rail and air travel.

Cloud seeding is often used in China in an attempt to bring on rain. The country's north is prone to droughts, while the south is often flooded.
