Cloud seeding What?

Nuclei How?

Guns Planes

Why? Expedite

Salts, calcium, chloride, dry ice or silver iodide.

Chinese use silver iodide because it is similar to ice crystals

Beijing’s water basins have increased over 13 percent

Cloud seeding often helps to cool temperatures

Static Silver Iodide

Dynamic Boosts vertical air currents = more water

Hygroscopic Disperses salts to enlarge rain drops

12,000 anti-aircraft guns and rocket launchers

30 planes 32,000-35,000 people participate

China spends 60-90 millions dollars a year

Pay farmers $100 / month to fire anti-aircraft guns
