Snow Flakes: Supercooled Cloud Droplets

vicked.vicky

Snow crystals form when tiny supercooled cloud droplets freeze. These droplets are able to remain liquid at temperatures lower than -18 °C (0r °F), because to freeze, a few molecules in the droplet need to get together by chance to form an arrangement similar to that in an ice lattice; then the droplet freezes around this "nucleus."
