Graupel: Snow's Little Cousins!

Imagine tiny, soft balls of snow, about the size of a pea or a small blueberry. That's graupel! It's not quite snow, and not quite hail.

Graupel forms when tiny water droplets in the air freeze onto falling snowflakes. These frozen droplets make the snowflake heavier and rounder, turning it into a graupel pellet. They feel soft and crunchy, like styrofoam, and they bounce when they land, unlike fluffy snow.

They are a special kind of winter treat from the sky!

Graupel is like a snowflake that got a special coating! Inside chilly clouds, there are super-cold water droplets that haven't frozen yet. When a snowflake falls through these droplets, the droplets stick to it and freeze instantly.

This happens over and over, adding more layers like frosting on a cake. Each layer makes the snowflake bigger and rounder. Eventually, it becomes a graupel pellet, ready to tumble down to Earth.

It's a cool way for snowflakes to get a makeover!

Graupel and hail are both made of ice, but they are very different! Hailstones are hard and can be as big as golf balls or even bigger, and they hurt if they hit you. Graupel, on the other hand, is soft and squishy, like tiny marshmallows made of snow.

Hail forms in powerful thunderstorms with strong winds that toss ice balls up and down to grow. Graupel is gentler, forming when snowflakes collect freezing water droplets. So, graupel is like a soft, crunchy cousin to the hard, bumpy hail.

You might see graupel falling during winter storms, especially when it's cold but not freezing cold. It can also happen in thunderstorms, but it's usually smaller and softer than hail. Sometimes, graupel falls in places high up in the mountains, even when it's not winter.

It's a sign that the weather is doing something interesting! If you ever feel little crunchy pellets bouncing off your coat, you've probably met some graupel. It's a fun part of Earth's weather!
