- Snowflakes are small and delicate, because they are limited by the amount of water vapor surrounding them as they grow in the atmosphere. The crystals often grow in fractal and jagged patterns. Ice cubes formed in the freezer are made of many tiny ice crystals that formed quickly and grew into each other.

Wilson Bentley (1865–1931) from Jericho, Vermont, was the first person to capture photographs of snowflakes through a microscope attached to a camera. His collectionof over 5,000 images – no two alike – introduced many people to the astounding diversity of snow crystals.
In 1951, scientists from an organization now called the International Association of Cryospheric Sciences (IACS) devised a classification system that characterized snowflakes into 10 basic shapes. Kenneth Libbrecht, professor of physics at the California Institute of Technology, in his guide to snowflakes at SnowCrystals.com, provides this chart of...
Libbrecht has made extensive observations of how water molecules get incorporated into snow crystals. In his research, he observed that the most intricate snowflake patterns form when there is moisture in the air. Snowflakes produced in drier conditions tend to have simpler shapes. According to Libbrecht’s research, temperature also has a large eff...
Bottom line: Temperature and humidity influence snowflake shape. The most intricate snowflake patterns form during warm and wet conditions. Read more from NOAA
Dec 8, 2021 · Snowflakes begin life high up above us, in water-saturated, very cold, clouds. It takes just the right balance of high humidity and low temperatures for their formation.
Jan 12, 2023 · As the snowflake grows, the attachment of water molecules is determined by the temperature and humidity of the air. Since these characteristics don’t change too much at the size of a growing snowflake, those attachments tend to occur evenly across the six points of the hexagonal flake.

Dec 19, 2023 · Through their analysis of over half a million snowflakes and the development of novel instrumentation, they have revealed a surprisingly simple pattern underlying the movement of these delicate ice crystals.
