The real rainy season comes in summer, and Chinese meteorologists have trained for the Summer Olympics by practicing their “rain mitigation” techniques at recent special events. They’ve had several successes.
'Weather modification' team will manipulate the clouds in summer to try to keep the open-air stadium dry.

BEIJING -- It is yet another attempt by man to triumph over nature.
Determined not to let anything spoil their party, organizers of the 2008 Summer Olympics said Wednesday that they will take control over the most unpredictable element of all -- the weather.
While China's Olympic athletes are getting ready to compete on the fields, its meteorologists are working the skies, attempting the difficult feat of making sure it doesn't rain on the Aug. 8 opening ceremonies.
"Our team is trained. Our preparations are complete," declared Wang Jianjie, a spokeswoman from the Beijing Meteorological Bureau, addressing a news conference at the headquarters of the Beijing organizing committee.
The Chinese are among the world's leaders in what is called "weather modification," but they have more experience creating rain than preventing it. In fact, the techniques are virtually the same.
Cloud-seeding is a relatively well-known practice that involves shooting various substances into clouds, such as silver iodide, salts and dry ice, that bring on the formation of larger raindrops, triggering a downpour. But Chinese scientists believe they have perfected a technique that reduces the size of the raindrops, delaying the rain until the clouds move on.

Training with the Olympics in mind, the meteorologists have been practicing their "rain mitigation" techniques since 2006. They have had a couple of dry runs, so to speak -- a China-Africa summit and a panda festival in Sichuan province, among others.
The Chinese have been tinkering with the weather since the late 1950s, trying to bring rains to the desert terrain of the northern provinces.
The bureau of weather modification was established in the 1980s and is now believed to be the largest in the world. It has a reserve army of 37,000 people -- most of them sort of weekend warriors who are called to duty during unusual droughts. The bureau has 30 aircraft, 4,000 rocket launchers and 7,000 antiaircraft guns, said Wang Guohe, director of weather modification for the Chinese Academy of Meteorology.
"We have the largest program in the world with the most people involved and the most equipment, but it is not really the most advanced," Wang said. That honor belongs to the Russians, who he says used sophisticated cloud-seeding in 1986 to prevent radioactive rain from the Chernobyl reactor accident from reaching Moscow.
