A day to look up
Every year in September, people around the world celebrate International Cloud Appreciation Day. The day began with a simple idea from a British writer, Gavin Pretor-Pinney, who started the Cloud Appreciation Society in 2005. He believed that clouds, in all their shapes and colours, deserved more attention.
The first official Cloud Appreciation Day was held in 2022. On this day, people are invited to look up at the sky, notice the clouds, and share photos of what they see with the Cloud Appreciation Society.
These images are collected in the Memory Cloud Atlas, an online gallery of skies from all over the world. Families, students, artists, and photographers all join in. Anyone can take part; all you need to do is look up and snap a picture.
What are clouds?
Clouds are made of tiny drops of water or ice crystals that float in the air. They form when warm air rises, cools, and releases moisture. Clouds might look light and fluffy, but a single cloud can actually hold tonnes of water!
Why do clouds matter?
Clouds are not just pretty to look at. They play an important role in nature and in our daily lives:
- They bring rain and snow, which plants, animals, and people need to survive.
- They help keep the Earth cool by reflecting sunlight.
- They move water around the planet as part of the water cycle.
Without clouds, life on Earth would be very different, if not impossible.
Different shapes and types
Not all clouds look the same. Scientists group clouds into types:
- Cumulus: Big, fluffy white clouds, often seen on sunny days.
- Stratus: Flat, grey clouds that can cover the whole sky.
- Cirrus: Thin, wispy clouds high in the sky.
- Cumulonimbus: Huge storm clouds that rise high and can bring thunder and lightning.
When you look up, try to notice the shapes. Sometimes people see animals, castles, or faces in the clouds. It is like nature’s own art show.
Why do people celebrate International Cloud Appreciation Day
International Cloud Appreciation Day is about slowing down and noticing the world above us. Clouds belong to everyone, no matter where we live. For just a few minutes, looking at the sky can connect us with people everywhere who are doing the same thing.
So next time you step outside, pause and look up. What do you see drifting across the blue? A sheep, a ship, or maybe just a fluffy friend?
