Wind shear can occur in wispy cirrus clouds or even in clear air near thunderstorms, as differences in temperature and pressure create powerful currents of fast-moving air.

Sun halos are optical illusions created when ice crystals form in the correct shape in the upper atmosphere, usually accompanying thin, wispy cirrus clouds.

Those harmless-looking vapor trails sometimes spread out to form thin cirrus clouds.

The remaining, thinner cirrus clouds would allow more long-wave radiation emanating from Earth to escape to space.

Aside from those brief glimpses through the storm, the cirrus clouds resembled a flat blanket beneath the deep blue sky.
