Warm Front Bands are accompanied by cloud bands which usually are shorter than Cold Front cloud bands.
Middle and high level cloud in a rising warm, moist air stream relative to its system velocity.
Cut off low in upper levels without corresponding surface low, accompanied by cloud bands at the boundaries and convective cloud in the low center.
Organised cloudiness in the thickness ridge in front of a Cold Front which can be extremely convective in unstable situations.
Low and middle level cloudiness develops at the windward side of mountains if the wind streams almost perpendicularly to the mountain barrier.
One typical occurence of Cbs and Mesoscale Convective Systems is within the area of hot air over Spain, in front of an approaching Cold Front.
Secondary Low Centres are small scale cloud vortices which develop within already mature Occlusion cloud bands.
Unstructured patches of low cloud within a stable stratified troposphere.
