A leading Chinese meteorologist says the country will employ more rainmaking technology and make better use of it in the next five years.
Some 560,000 manipulations of the weather have been conducted since 2002 using aircraft, rockets and projectiles carrying dry ice or silver iodide particles to stimulate rainfall, resulting with release of 489.7 billion tons of rain and saved about $10.4 billion in economic losses the China Meteorological Administration reported.
China started with weather modification program in 1958. For the 2008 Olympics, China had 30 airplanes, 4,000 rocket launchers, and 7,000 anti-aircraft guns to stop rain. Each system would shoot various chemicals into any threatening clouds to shrink rain drops before they reach the stadium. In February 2009, China also blasted iodide sticks over Beijing to artificially induce snowfall after four months of drought, and blasted iodide sticks over other areas of northern China to increase snowfall. The snowfall in Beijing lasted for approximately three days and led to the closure of 12 main roads around Beijing. At the end of October 2009 Beijing claimed it had its earliest snowfall since 1987 due to cloud seeding.
