How are stratocumulus clouds formed?
How do stratocumulus clouds form? Stratocumulus clouds usually form from a layer of stratus cloud breaking up. They are indicators of a change in the weather and are usually present near a warm, cold or occluded front.
What kind of weather does stratocumulus bring?
Most often, stratocumulus produce no precipitation, and when they do, it is generally only light rain or snow. However, these clouds are often seen at either the front or tail end of worse weather, so they may indicate storms to come, in the form of thunderheads or gusty winds.
What type of clouds are stratocumulus?
Stratocumulus clouds are hybrids of layered stratus and cellular cumulus, i.e., individual cloud elements, characteristic of cumulo type clouds, clumped together in a continuous distribution, characteristic of strato type clouds. Stratocumulus also can be thought of as a layer of cloud clumps with thick and thin areas.
What height do stratocumulus clouds form?
Stratocumulus top heights are typically 500–2000 m over the Earth, confined mostly by the inversion height of atmospheric boundary layers. Stratocumulus clouds can exist within both well-mixed and intermittently coupled boundary layers.
Can stratocumulus clouds produce rain?
Many cumulonimbus clouds occur along cold fronts, where cool air is forced under warm air. They usually shrink as evening approaches, and moisture in the air evaporates. Cumulonimbus clouds gradually become stratocumulus clouds, which rarely produce rain. Certain types of clouds produce precipitation.
Do stratocumulus clouds bring rain?
Stratocumulus Clouds. Stratocumulus clouds like these are often associated with rain or other types of precipitation. They are fluffy and relatively low to the ground. Clouds are visible accumulations of tiny water droplets or ice crystals in the Earth’s atmosphere.
Where does a Stratus and stratocumulus form?
108 The formation of stratus and stratocumulus can take place from a cooled or moistened 109 clear sky. Stratocumulus can emerge from the transition of another cloud type, most commonly 110 cumulus and stratus. From the clear sky, longwave cooling drives the clear boundary layer 111 toward condensation.
How does a stratocumulus affect the cloud layer?
Thicker stratocumuli have more cloud-top condensate than 55 thinner ones, so that the strength of cloud top entrainment increases with stratocumulus cloud 56 thickness. Cloud top entrainment mixes in warm, dry air into the boundary layer, raising the 57 cloud base and thereby thinning the cloud layer.
How is the entrainment of 52 stratocumulus aided?
Cloud top entrainment in 52 stratocumulus is strongly aided by the evaporation of cloud water into a thin layer just above 53 cloud, which cools the air parcels in the mixing region, making them sufficiently negatively 54 buoyant to sink into the cloud layer.
What causes 80 turbulent eddies in stratocumulus layer?
The 80 turbulent eddies in stratocumulus layers are initiated by cloud top longwave cooling but are 81 strengthened by latent heat release in updrafts and evaporative cooling in downdrafts.
