Abstract: Water is one of the most basic resources on earth sustaining human life. The
insufficient of water prompted scientists and engineers to explore the possibility of
augmenting water supplies by means of cloud seeding. Cloud seeding is a form of
weather modification, a way of changing the amount or type of precipitation that
falls from clouds, by dispersing substances into the air that serve as cloud condensation
or ice nuclei, such as dry ice and silver iodide (AgI). Some numerical simulation on
the surface of AgI crystal were made by molecular dynamics, which was limited by the
time and length scales. Now we want to use a continuity model (phase field crystal) to
simulate and explore the nucleation in the process of cloud seeding.
