China’s droughts have become so severe that the meteorological department of Yichuan county have began seeding with what appear to be anti-aircraft guns! Rather than deadly ammunition these large caliber guns are loaded with chemical mixtures, silver iodide, which are able force clouds to precipitate. In this a nice coating of winter snow was the result of the manipulation technique. Cloud seeding has also been carried out in Henan, Shandong, Jiangsu and Anhui. Beijing, which has seen it’s longest winter drought in 60 years this year is also preparing for seeding, although the recent snow fall may hold off those plans.
