The cloud seeding project was coordinated by ------, the head of ----- in China. The project had been successful in previous years increasing rainfall by 1/6 inch. There are two different methods for cloud seeding for the different two types of clouds. The first method is more effective for warm clouds and is carried out by hygroscopic seeding. Hygroscopic seeding initiates precipitation by introducing a liquid and salt, usually through a torch, into the atmosphere using a plane to deliver the salt and liquid-filled torches (Introduction of Seeding Agents). As the flame burns, the salt is released and small droplets of water stick to it. The second type of cloud seeding, glaciogenic seeding, is used with warm clouds (Introduction to Seeding Agents). Essentially the seeding agents, silver iodine and dry ice, are distributed into the clouds via aerial means to create more ice crystals to which water droplets attract, creating heavier clouds that will rain sooner. Although these methods are relatively effective and safe for the environment and people, the long-term effects are unknown. This has caused concern among people who believe cloud seeding is releasing unwanted chemicals into the air. People are also starting to link cloud seeding to the mysterious chemtrails they saw left behind
