Quantitative Modeling of Faceted Ice Crystal Growth from Water Vapor Using Cellular Automata

Figure 3

The dashed line shows the analytic result for the growth of an infinite cylinder with 𝛼=1, 𝑅_out=43.5𝜇m, and 𝜎_𝑅out=0.01, as described in the text. Solid lines show numerical modeling results using 𝐴_speed=0.2 (top line), 0.02 (middle line), and 0.002 (bottom line).
