EarthSky | Are 2 snowflakes ever the identical?

View larger at EarthSky Community Photos. | Sheryl R Garrison in Southern Alberta, Canada, captured this pretty closeup picture of a snowflake on November 9, 2022. She stated: “Every winter I try to photograph snowflakes in honor of Wilson (Snowflake) Bentley, the first person to photograph a single ice crystal in 1885. While he would capture them on black velvet, I enjoy hunting for them on natural surfaces. This snowflake was photographed on a raspberry leaf. The temperature was -18 C.” Thank you, Sheryl!

Snowflakes are available in all totally different shapes

Snowflakes are crystals. Indeed, you may see them in many alternative shapes if you happen to allow them to fall on a black floor and take a look at them with a magnifying glass.

But, not all snowflakes are the lacy or star-type snowflakes we take pleasure in in photos. In reality, a spread of various basic shapes type at totally different temperatures, so the type of snowflake depends upon the temperature of the cloud during which it shaped. For instance, comparatively heat clouds yield lacy or starry snowflakes. On the opposite hand, very chilly clouds yield snowflakes often known as “columns.”

In reality, we’ve all heard that no two snowflakes are alike, and that’s true of the star-shaped ones.

On the opposite hand, column-type snowflakes have easy, strong prism shapes – a lot as if you happen to reduce a piece out of a lead pencil. While the ratio of their size to thickness can range, column-type snowflakes don’t have a sophisticated construction. Many are very a lot alike.

By the best way, even these column snowflakes aren’t an identical if you look carefully – on the degree of the snowflake’s molecules.

A number of years again, we talked to Charles Knight on the National Center for Atmospheric Research in Boulder, Colorado. And he stated:

I don’t know why folks decide on snowflakes; are any two geraniums alike? Or kittens, or mountains or asteroids?

Bottom line: Not all snowflakes are the attractive lacy or star formed snowflakes we see in photos, and no two of them are alike. Some are fundamental shapes often known as columns. It all depends upon the temperature of the cloud the place they shaped.
