Weather modification is the act of intentionally manipulating or altering the weather. The most common form of weather modification is cloud seeding to increase rain or snow, usually for the purpose of increasing the local water supply. Weather modification can also have the goal of preventing damaging weather, such as hail or hurricanes, from occurring; or of provoking damaging weather against the enemy, as a tactic of military or economic warfare. Weather modification in warfare has been banned by the United Nations. ==History== Wilhelm Reich performed cloudbusting experiments in the 1950s to 1960s, the results of which are controversial and not widely accepted by mainstream science. Dr Walter Russell wrote of weather control in Atomic Suicide 1956."--give him complete power to cause rains, wherever he desires, on deserts or meadows and to dissipate cyclones while forming." For the 2008 Olympics, China had plans to utilize 30 airplanes, 4,000 rocket launchers, and 7,000 anti-aircraft guns in an attempt to stop rain. Each system would shoot various chemicals into any threatening clouds in the hopes of shrinking rain drops before they reached the stadium.〔(Demick, Barbara, "China plans to halt rain for Olympics," ''Los Angeles Times,'' January 2008 ).〕 In January, 2011, several newspapers and magazines, including the UK's ''Sunday Times'' and ''Arabian Business'', reported that scientists backed by the government of Abu Dhabi, the capital of the United Arab Emirates, had created over 50 artificial rainstorms between July and August 2010 near Al Ain, a city which lies close to the country's border with Oman and is the second-largest city in the Abu Dhabi Emirate. The artificial rainstorms were said to have sometimes caused hail, gales and thunderstorms, baffling local residents.〔Leigh, Karen. (), "Arabian Business", January 3, 2011. Retrieved 2011-01-8.〕 The scientists reportedly used ionizers to create the rainstorms, and although the results are disputed, the large number of times it is recorded to have rained right after the ionizers were switched on during a usually dry season is encouraging to those who support the experiment.〔(), "Daily Mail", January 3, 2011.
