Snowflake Structure Still Mystifies Physicists. Flakes’ final shape depends on an array of temperature, humidity and wind speed variables. By Leslie Nemo edited by Andrea Gawrylewski.

We’ve all heard it—no two snowflakes are alike. However, they all seem to share that same six-sided shape, so what’s […] ...

Every snowflake is unique, here's the science to back it up. ... Despite their variety, all snowflakes share six-sided symmetry, a result of ice’s molecular structure.

Snowflakes and snow crystals can grow fairly large, ... The diverse shapes are loosely entangled in a precarious, three-dimensional structure that tends to be elongated rather than spherical.

While people often assume a 10:1 ratio, SLR can vary widely depending on temperature, humidity, and snowflake structure, leading to different snowfall totals.

"As you stare outside at the snow globe, know that those snowflakes were likely generated at about 5,000-15,000 feet above the ground between -10C (14F) to -20C (-4F)," NWS Milwaukee wrote. Given ...
