The rainy season has come to northern China, and it’s a brave new world out there. Actually the natural rainy season doesn’t start until July. But the season of man-made rain is upon us, and Chinese rainmakers have been busy. Over the past month they've mobilized cloud-seeding aircraft, artillery and rockets to enhance rainfall. "We've ordered technicians to try to make it rain again today, but so far they haven’t reported back on the results," says Zhang Qiang, a businesslike woman who heads the Beijing Weather Modification Office (yes, that’s the official name of a real Chinese government agency). "We did it many times last week to increase the rainfall."

Not content with simply making it rain, now China's weather modifiers have taken on another meterological mission: to help guarantee perfect weather when Beijing hosts the Olympic Games in 2008.

Zhang's office, which employs 30 people, is part of the Beijing municipal government and the nationwide China Meteorological Administration. Her unit uses two aircraft and 20 artillery and rocket-launching bases to help modify weather around the city. Springtime is the busiest season for agricultural purposes. But more and more, Zhang and her colleagues are experimenting with weather modification to try to create blue skies. Toward this end, they’ve spent nearly a month and a half total researching the effects of certain chemical activators on different sizes of cloud formations and at different altitudes. Chinese meteorologists claim that similar efforts helped create good weather for a number of past VIP events in China, including the World Expo in Yunnan, the Asian Games in Shanghai and the Giant Panda Festival in Sichuan.

And why not? The central-government leadership—dominated by engineers—has been messing with Mother Nature ever since the Chinese Communist Party came to power. They’ve built the world’s biggest dam, the world’s highest railway and even the world’s biggest Ferris wheel (in Nanchang, still awaiting verification from the Guinness World Records). Why not perfect the science of climate control?

Today Chinese rainmakers are among the world’s busiest. Beijing's nationwide weather-modification budget exceeds $50 million a year. The communist regime’s 11th Five Year Plan, which kicked off this year, calls for the creation of 48 billion to 60 billion cubic meters of artificial rain annually (somewhere between 12 trillion to 16 trillion gallons of water). Beijing needs it. Right now is when fruit trees and crops need life-giving water; the parched North China plain has been stalked by drought since 1998. Normal precipitation is between 22 and 24 inches annually, says Zhang, but Beijing had only 18 inches last year.
