What are cirrus clouds?

Cirrus clouds are super high-up fluffy clouds that look like wisps of hair floating in the sky.

Imagine you're wearing a really light sweater on a chilly morning, that's how cirrus clouds feel up there, made of tiny ice crystals instead of water droplets. They’re so high in the sky that they often look like thin, feathery lines or even cotton candy strands drifting lazily across the blue.

Cirrus clouds are born when cold air meets warm air way up in the sky, kind of like how your breath fogs up on a cold day. The temperature is so low that the water vapor turns into tiny ice crystals, which then bunch together to make those fluffy, soft clouds.

They can be as simple as a few whispy lines in the sky or as full as a feathery blanket covering part of the sky. Sometimes you might even see them changing shape slowly, it's like watching someone draw with invisible chalk in the sky!
