Cirrocumulus stratiformis is a type of cirrocumulus cloud. The name cirrocumulus stratiformis is derived from Latin , meaning "stretched out". [ 2 ] Cirrocumulus stratiformis occurs as very small cirrocumulus clouds that cover a large part of the sky.
Cirrocumulus is one of the three main genus types of high-altitude tropospheric clouds, the other two being cirrus and cirrostratus. [3] They usually occur at an altitude of 5 to 12 km (16,000 to 39,000 ft), however they can occur as low as 10,000 ft (3.0 km) in the arctic and weather reporting standards such as the Canadian MANOBS suggests heights of 29,000 ft (8.8 km) in summer and 26,000 ft ...
Cirrocumulus stratiformis undulatus (V-17) Cirrocumulus lenticularis undulatus [12] (V-18) Lacunosus Cirrocumulus with large clear holes; normally associated with stratiformis and castellanus species (also with cumuliform floccus species). Stratocumuliform lacunosus Cirrocumulus stratiformis lacunosus (V-19) Cirrocumulus castellanus lacunosus ...
Stratocumuliform genus-types (cirrocumulus, altocumulus, and stratocumulus) that appear in mostly stable air with limited convection have two species each. The stratiformis species normally occur in extensive sheets or in smaller patches where there is only minimal convective activity. [78]
A fallstreak hole (also known as a cavum, [1] hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. The holes are caused by supercooled water in the clouds suddenly evaporating or freezing, and may be triggered by passing ...
Cirrus radiatus is a variety of cirrus cloud.The name cirrus radiatus is derived from Latin, meaning "rayed, striped". [1] This variety of cirrus clouds occurs in parallel bands that often cover the entire sky and appear to converge at a single point [2] or two opposite points on the horizon.
Cirrocumulus appears almost exclusively with cirrus some way ahead of a warm front and is a reliable forecaster that the weather is about to change. [4] When these high clouds progressively invade the sky and the barometric pressure begins to fall, precipitation associated with the disturbance is likely about 6 to 12 hours away.
This should be sensible at the surface if one is in the inflow region; in the Northern Hemisphere, this is typically to the south and southeast of the wall cloud. Large tornadoes tend to come from larger, lower-wall clouds closer to the back of the rain curtain (providing less visual warning time to those in the path of an organized storm).
