Magono & Lee Classification of Snow Crystals Page 9
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.

I1 Ice particle
CP1a Column with plates
or Capped Columns Capped Coluumns are basically crystals which start out as columns, but suddenly switch to plate-like growth. This phenomon may happen if a crystal gets blown into a region with a different temperature.
R1b Rimed columnar crystal
I2 Rimed particle
CP1b Column with dendrites
R1c Rimed plate or sector
