Is it just me, or should China think this whole deal over a little bit more than they have??
China rolls out the big guns, aiming for a dry Olympics

FRAGRANT HILLS, China — When he's not tending cherry orchards outside Beijing, Yu Yonggang can be found behind the twin barrels of a 37mm anti-aircraft gun, blasting shells at passing clouds.
Yu is one of 37,000 peasants enlisted by the Chinese government to help produce rain in parched areas. The 45-year-old farmer works with China's other trigger-happy rain men to water the crops, break up damaging hailstorms and put out forest fires. After a sandstorm blew through the capital in May, he lobbed shells and rockets skyward to coax rains that washed sand and grit from city streets.
Now Yu and the other rainmakers face their toughest challenge: making sure it stays dry for the opening ceremony of the 2008 Beijing Olympic Games. The idea is for the peasant gunners to work with meteorologists watching radar in the capital. Together, they will hunt pregnant rain clouds and pound them with rockets containing silver iodide. The hope is that any moisture will fall before the clouds can threaten the parade of athletes and lighting of the Olympic flame at the new National Stadium.
China's leaders want the Games to be a showcase for the country's astonishing economic development. The cloud-busting effort shows how far they will go to ensure that nothing interferes with the pageantry.
Yu, who wears a green military jacket and helmet in his gunner's seat, is already feeling pressure to perform. "The whole world will be watching the ceremony," he says. "We must guarantee its success."
In August, the Beijing Weather Modification Office will place the area's 20 firing sites on standby for a major test. In the Fragrant Hills west of Beijing, Yu and six others at the Man-Made Hail-Prevention and Rain-Increasing Work Station will be at the ready, manning four anti-aircraft batteries, which are army castoffs from the 1960s. Yu's wife will talk to Beijing by walkie-talkie, getting the all-clear from aviation authorities and relaying the firing order from the meteorologists. Yu says he hopes to dissipate any clouds completely, increasing the barrage and concentrating his fire if necessary.
Two summers from now, "if rain clouds are headed toward the Olympic stadium, we will intercept them," says Zhang Qiang, a "weather modifier" at the Beijing Meteorological Bureau who will issue the command. "But I can't guarantee the ceremony (will be dry). If there is a big rainstorm, I have no way to stop it."
The U.S. pioneered cloud-seeding in the 1940s and '50s, but the government has cooled on its effectiveness, leaving the field to specialist companies. In China, among the most water-poor nations, the state tries to squeeze every drop from above.
"China has the largest rainmaking (operation) in the world," ahead of Russia and Israel, says professor Wang Guanghe, a 20-year rainmaking veteran at China's Meteorological Sciences Academy. "Each province reports results to us of between 10% to 25%" additional rainfall.
The Chinese government rarely shirks nature's challenge. It recently completed the $25 billion Three Gorges Dam, the world's largest, which was built despite the objections of environmentalists at home and abroad. Weather manipulation is an enthusiastic past-time for Beijing, possibly because so many of the country's Communist leaders are engineers.
The forecast calls for more rain. China's five-year plan urges an increase in man-made precipitation. Central planners want an additional 65 billion cubic yards a year — nearly enough to fill the Yellow River, the country's second-largest river.
China began cloud-busting in 1958. Now "it is increasing every year," says Wang, who cites the drought plaguing northern China as the main reason to fire rain-inducing shells or soar into the skies in cloud-seeding airplanes.
Any chemical fallout is negligible, Wang says. "We have found no evidence of pollution in the rain."
The need for rainwater has produced squabbles on the ground. Two years ago, five thirsty cities in Henan province accused each other of "cloud theft" for their efforts to trigger chemically induced showers.
Older generations of Chinese used to beat bells to pray for rain, Yu recalls. Today, he puts his faith in cigarette-sized sticks of chemicals loaded inside rockets and shells. "Every time we fire, it rains — lightly or heavily," says the farmer, who earns $125 a month during the May-to-September firing season. "At first, the other villagers didn't believe we could make it rain, but most accept it now."
In the Fragrant Hills, locals complain about noise from Yu's guns. He says he's had to fit the firing station with thicker glass because powerful shocks from his anti-aircraft barrages smashed windows.
Annual training programs and the use of licenses have curbed accidents among China's rainmakers, Wang says. Even so, a passerby in southwest Chongqing was killed by part of a rain cannon that flew off during firing in May.
Zhang, the Beijing meteorologist, says most farmers see the benefit of cloud-seeding and welcome chemically induced rains. Five years ago, a storm near the capital killed 139 ducks, crushing them with hailstones. Today, such incidents are rare, she says.
Rain won't be the only threat when the Olympics take place in 2008. Beijing's smog is as big a threat to China's image-makers as a few raindrops.
That's somebody else's problem, says weather guru Zhang: "I can't do anything about the air pollution."
