Magono & Lee Classification of Snow Crystals Page 2

Magono and Lee Developed their Comprehensive Snow Crystal Chart in 1966

These two snow scientists conducted extensive field work on weather conditions, moisture, temperature, etc., that affect snow crystal formation.

Their article "Meteorological Classification of Natural Snow Crystals," appeared in the Journal of the Faculty of Science, Hokkaido University, Japan.

Magono & Lee classification of snow crystals includes 80 different snow crystal types arranged into a comprehensive scheme that provides a numbering and lettering system to categorized snow crystals according to shape and structure.

• Magono and Lee Classification this government educational site provides photographs of crystals to match each classification symbol. Very cool!
• Ken Libbrecht's Snowflake Classifications
• More historic research of ice, snow and snowflake patterns
