Investigating cloud-seeding

The Queensland government in Australia invested resources into studying the feasibility of precipitation enhancement through cloud seeding to supplement water resources. Cloud seeding technologies aimed to convert more of the water vapor processed in the cloud to more rainfall at the ground, increasing the cloud's precipitation efficiency. The technology aimed to add particles to a cloud that helped in developing precipitation more efficiently, yielding more rainfall. The hygroscopic particles were carried into the cloud by the updraft. Water vapor condensed them to form additional liquid cloud droplets whose size depended on the size of the hygroscopic particles introduced in the cloud. The addition of additional particles of larger sizes potentially helped in enhancing collision and coalescence processes that were responsible for rain formation and convert more of the cloud water to rainfall.
