- Cirrus clouds are thin and wispy and look like stretched cotton. You can see through them.
- They are high-level clouds that are made of ice crystals.
- Cirrus clouds usually mean nice weather, however, they can occur just before a change of weather.
- When the ends of cirrus clouds are curled, this is a sign that the wind is going to change directions. The word cirrus means curl of hair.
- Nimbus clouds are darker than other clouds and often mean a thunderstorm is brewing.
- The word nimbus means a cloud that already has rain or snow falling. Nimbus is often added to other cloud names.
- Nimbostratus is also used, which means a stratus cloud with rain.
