Snowflake science explained : vimarsana.com

In winter you’ll often hear meteorologists refer to two types of snowmakers, a Nor’easter and an Alberta Clipper. But just because these winter storms make snow, doesn’t make them the same.
Snow is an all-too-familiar feature of the colder months across much of the U.S., but how much do you know about the science of snowflakes?
There will be plenty of snowflakes falling on Wednesday with a major Nor’easter expected to bring heavy snow.
A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky, explains NOAA on its website. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.
