No two truly identical snowflakes exist not only on Earth, but also in the Universe. The probability that two snowflakes will experience the same conditions down to the microscopic level is very low.
The Ukrainian Hydrometeorological Center says that there are more than 135 types of snowflakes. The largest of them measured 3.5 centimeters, while most barely reached 5 millimeters.
“In fact, snowflakes are completely transparent, because they are formed from pure ice. However, we see them as white – this is due to the reflection of the entire spectrum of light on the small faces of the snow crystal.” – the Hydrometeorological Center notes.
They explain that the basic shape of an ice crystal is determined by the temperature at which it forms and air humidity (to a lesser extent).
“Long needle-like crystals form at -5℃, and very flat lamellar crystals – at -15℃. After birth, each snowflake lives its own life and acquires a shape that no other will ever repeat.” – say forecasters.
All snowflakes tend to have the symmetrical shape of snowflake dendrites, but their fragile structure is easily broken, forming a new shape.
“That’s why absolutely every snowflake looks unique, starting from the lacy pattern and ending with the uniqueness of each ice needle.” – summarized in the Hydrometeorological Center.
