Jet Fibres are long and narrow bands of high clouds caused by the Jet streak. They usually form directly attached to Cold Fronts or Warm Front Shields.

During an Instant Occlusion process, a Comma approaches and merges with a frontal cloud band. As a consequence, an Occlusion-like form of a cloud spiral…

Orography has a strong influence on the propagation of frontal cloud bands; some parts can be retarded which might result in a delay or a decoupling of…

Foehn is a wind system created by the impact of orographic obstacles like mountains on the flow, which often shows a typical cloud structure.

Smooth, very low cloud sheets with warm tops called Stratus unless reaching the ground in which case they are Fog.

Mesoscale areas of cloud dissolution within frontal cloud bands driven by sinking cold air on the anticyclonic side of a jet streak.

Enhanced Cumulus areas (ECs) consist of a cluster of thicker and larger cloud cells within the usual cold air cloudiness behind frontal cloud bands.

Cloud bands or lines which form within a deformation field and stretch or dissolve under the influence of elongation.
