1. When cirrostratus clouds are disturbed by planes or strong winds, the droplets can freeze instantly or evaporate, the latter of which will form the hole.

2. These clouds occur within cirrostratus clouds, which are often composed of ice crystals and drops of water that are below freezing temperature but still in liquid form.

3. In this case, shifting winds have formed a cirrostratus fibratus cloud into a herringbone pattern.

4. Cirrostratus clouds, thin white streaks of cloud, merge with fluffy balls of cirrocumulus clouds at heights above 20,000 feet.

5. These occur in cirrus or cirrostratus clouds, which are often composed of ice crystals and super-cooled water droplets – water that is below freezing temperature, but still in liquid form.

6. The normally matte-black ablative coating on her dorsal surfaces flickered with patterns of cirrostratus and lapis ocean and glowing orange sunset.
