How Beijing used rockets to stop the rain

In order to produce an impeccable opening ceremony, Beijing instituted a "weather modification" department in charge of making sure it wouldn't rain over the roofless Olympic stadium. Did their 4,687 rocket launchers work?

"China's cunning multimillion-pound plan to manipulate the Olympic weather seems to be yielding results. While rain drenched the capital yesterday, the downpour that should have fallen on Friday night was averted; Olympic organisers fired a barrage of 1,110 rockets into the evening sky to make sure the 2008 Olympic opening ceremony was precipitation-free.

Friday saw the biggest effort yet, as the"weather changers" began firing rockets from a battery of artillery into the clouds above Beijing four hours before the opening ceremony and continued firing until 11.40pm, shortly before the finale.

The rockets were fired from 21 sites in the city, intercepting a potentially disruptive rain belt and triggering premature showers before they reached the capital. Baoding city, south-west of Beijing, received about 100mm (4in) of precipitation on Friday night but in the capital the rain held off, even though August is the rainy season in normally tinder-dry Beijing."
