Scanning electron microscope image of rime frost on both ends of a capped column snowflake Once a water droplet has frozen as an ice nucleus, it grows in a supersaturated environment—wherein liquid moisture coexists with ice beyond its equilibrium point at temperatures below freezing.
The snowflakes were too complex to record before they melted, so he attached a bellows camera to a compound microscope and, after much experimentation, photographed his first snowflake on January 15, 1885. [5] He captured more than 5,000 images of crystals. Each crystal was caught on a blackboard and transferred rapidly to a microscope slide.

The hexagonal snowflake, a crystalline formation of ice, has intrigued people throughout history.This is a chronology of interest and research into snowflakes.

Graupel (/ ˈ ɡ r aʊ p əl /; German: [ˈɡʁaʊpl̩] ⓘ), also called soft hail or snow pellets, [1] is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime. [2] Graupel is distinct from hail and ice pellets in both ...
