Beautiful cirrus clouds were floating in the sky.

Beautiful scale clouds were spread across the sky.

The first time I saw a noctilucent cloud, it felt like I was dreaming.

Thin clouds are floating in the sky.

There are altocumulus clouds in the sky.

When the volcano erupted, a glowing cloud covered the sky.

By chance, he met my old friend.

In the early morning, he brewed coffee and started his day.

He completed the project in a week.

I'm always busy during the daytime, and I only have time to rest at night.
