The work of the Office is largely aimed at hailstorm prevention or making rain to end droughts; they have also induced precipitation for purposes of firefighting or counteracting the effect of severe dust storms, as they did in the aftermath of one storm in April 2006 which dropped 300,000 tonnes of dust and sand on the city and was believed to have been the largest in five years.

More prominently, they have also been enlisted by the Chinese government to attempt to ensure that the 2008 Summer Olympics are free of rain, by breaking up clouds headed towards the capital and forcing them to drop rain on outlying areas instead.
