![]() This type of cloud also casts no shadow.Ĭirrocumulus clouds can easily be confused with cirrus, cirrostratus and altocumulus clouds. It resembles a cirrus cloud, but unlike the thin long whisps, it takes the form of tiny regular patches or ribbed strips. If the cirrus clouds start to thicken, the weather is likely to worsen.Ĭirrocumulus (Cc) - a sign of changeable weatherĭespite being relatively uncommon, a cirrocumulus cloud is very easy to spot in the sky. ![]() Generally speaking, as long as the cirrus remains fine and sparse, you can rely on the fact that the current weather will remain stable. However, reading cirrus clouds is a bit tricky as the way they develop can forecast both stable fine weather and a major deterioration. The resultant streaking of the cirrus clouds (cirrus uncinus) makes it possible to predict the direction of the wind and any changes to it. Cirrus clouds are made of ice crystals and when these crystals are large enough, they begin to fall to lower altitudes where they are carried by the wind. They are, nevertheless, an excellent way to gauge wind direction and wind changes. In the vast majority of cases, cirrus clouds do not bring precipitation with them. ![]() They can also be recognised by the fact that they produce beautiful halos (light phenomena in the atmosphere created by the sun or moon) due to the refraction and reflection of light. They are usually narrow bands or patches in the uppermost levels of the sky, casting no shadow on the ground.īecause they occur in regions of high altitude where temperatures are as low as -50 ☌, they are largely made up of ice crystals. Cirrus clouds are translucent, delicate clouds that are wispy, feathery and can look like tufts of hair (from the Latin word cirrus, meaning 'curling lock of hair').
