What does cirrocumulus portend?

Cirrocumulus introduced: Clouds are very small, and they often appear in groups, forming a water wave or fish scale. The cloud base in the cirrocumulus is 6000 ~ 8000 meters high, and the cloud body is composed of ice crystals, sometimes containing snowflakes or supercooled water droplets. The thickness of clouds is very small, usually only a few hundred meters, and the shading ability is not strong. Through the clouds, the contours of the sun and the moon can be distinguished, and clear light and shadow can be formed when the sun reaches the ground during the day. Observing the moon through the clouds at night, we can perceive the obvious cloud structure. Cirrocumulus is occasionally flaky, flocculent or fortress-like. ? Cirrocumulus does not cause precipitation.

Features: On the edge of the whole layer of cumulus, sometimes small cumulus appears, which is quite similar to the cumulus in cirrocumulus, but don't mistake it for cirrocumulus. Only those who meet one or more of the following conditions can be considered as cirrocumulus.
