© wetterkurs.ch
The name "intortus" (Latin for tangled) describes the characteristic, corkscrew-like shape of these clouds. Cirrus intortus often appears as fine, thin streaks or filaments in the sky, arranged in irregular, tangled patterns. These clouds consist mainly of ice crystals and are found high in the atmosphere.

Cirrus intortus can indicate atmospheric stability, but it is also a precursor to approaching weather fronts. When these clouds appear, it may signal changing conditions. Meteorologists often observe them to detect changes in the weather forecast at an early stage.
