snowflake under an electron microscope
| quote: | | So what you're seeing here is C-axis growth, followed by A-axes growth, followed by riming on the ends. So this snowflake formed in a relatively dry region (producing a solid column), moved into a warm, wetter region (producing the plates on the ends), and finally fell through a high water vapor region (droplets adhering to cause the riming on either end). The riming is probably only on the outside of the plates because they served to stabilize the crystal as it fell and prevent it from tumbling. |
