In the case of no orography, cloudiness in middle and high levels dominates with slight to moderate rain or drizzle

Parameter	Description
Precipitation	No precipitation or only slight drizzle/light snowfall.
Temperature	Cloud-covered areas in winter generally warmer, in summer cooler than adjacent cloud-free areas. Reduced diurnal variation of temperature within cloudy areas.
Wind (incl. gusts)	Light to moderate winds.
Other relevant information	Aviation hazards: icing within the cloud and large wind shears on top of the cloud. The advection of stratocumulus over an area can either prevent the formation of fog or disperse it if it has already formed.

Example above shows an extensive Sc Sheet north of the Black Sea. No precipitation is observed within the cloud area.
