Stratiform - Having extensive horizontal development, as opposed to the more vertical development characteristic of convection. Stratiform clouds cover large areas but show relatively little vertical development.
STRATIFORM Clouds composed of water droplets that exhibit no or have very little vertical development. The density of the droplets often blocks sunlight, casting shadows on the earth's surface.
stratiform - Descriptive of clouds of extensive horizontal development, as contrasted to the vertically developed cumuliform types. See stratus, altostratus, cirrostratus, nimbostratus, stratocumulus.
Stratiformis
(Stratiform Cloud [other than stratus]) Cloud spread out in an extensive horizontal sheet or layer thus presenting the appearance of Stratus. This term applies to Altocumulus, Stratocumulus, and, occasionally, to Cirrocumulus.
STRATIFORM- Stable clouds. Stratiform clouds lack convective development and occur in broad layers. The lifting that forms stratiform clouds is dynamic (slow rising air).
Stratiform clouds Layered clouds, such as altostratus, often produced by air overrunning.
Stratocumulus (Sc) Low clouds consisting of large, irregular puff or rolls arranged in a layer.
Stratiform: (of a cloud) having predominantly horizontal development.
Stratocumulus: a cloud of a class characterized by large dark, rounded masses, usually in groups, lines, or waves, ...
STRATIFORM - Term applied to a non convective environment. The term STRATUS is commonly used for clouds and means layers. A stratiform cloud is usually associated with stable or stabilizing air. Also called LAYERED.
cirrocumulus stratiformis"See stratiformis.
cirrocumulus undulatus"See undulatus.
cloud forms
stratiform: flat or layered
cumuliform: puffy or globular
cirroform: wispy, made of ice crystals ...
It most often falls from stratiform clouds, but can fall as snow showers from cumuliform ones. It usually appears clustered into snowflakes. It is reported as "SN" in an observation and on the METAR.
Situations involving isentropic lift often are characterized by widespread stratiform clouds and precipitation, but may include elevated convection in the form of embedded thunderstorms.
" The microphysics of the melting layer of precipitation is an important feature for stratiform precipitation. The melting layer's degrading effect on satellite communication links makes understanding it important as well.
The added lift often results in widespread low cloudiness and stratiform precipitation if the air is stable, or an increased chance of thunderstorm development if the air is unstable.
The fourteen cloud species are fibratus, uncinus, spissatus, castellanus, floccus, stratiform, nebulosus, lenticularis, fractus, humilis, mediocris, congestus, calvus, and capillatus.
LOW CLOUDS A term used to signify clouds with bases below 6,000 feet and are of a stratiform or a cumuliform variety. Stratiform clouds include stratus and stratocumulus. Cumuliform clouds include cumulus and cumulonimbus.
Convective Rings and Bands Like "Stratiform Rings and Bands" they occur outside the eye wall of the hurricane. They exhibit a VIP Level 2 or greater reflectivity and occasionally display the "bright band" aloft.
These are named stratus clouds (or stratiform, the Latin stratus means layer) and cumulus clouds (or cumiloform, cumulus means piled up). These two cloud types are divided into four more groups that distinguish the cloud's altitude.
Precipitation of liquid water that falls from stratiform cloud, with diameter greater than 0.5mm. It is generally steadier than showers. Precipitation (from stratiform cloud) with droplets less than 0.5mm is called drizzle.

Stratocumulus (Sc) A principal low-level cloud type (cloud genus), predominantly stratiform, in the form of relatively low gray and/or whitish layer, sheet or patch. Its elements are often arranged in bands or rolls that lie across the wind.
Continuous Precipitation: Term applied to precipitation caused by stratiform clouds which persists for one hour or longer.
Convection: Transfer process due to the movement of air vertically.
After the precipitation has ended, a squall line is seen moving into the eastern horizon. Stable, stratiform clouds (those that develop in layers rather than clumps) predominate on the rear flank of a squall line.

Stratocumulus A low cloud, predominantly stratiform with low, lumpy, rounded masses, often with blue sky between them.
Stratopause The boundary between the stratosphere and the mesosphere.
Air that flows toward higher terrain, and hence is forced to rise. The added lift often results in widespread low cloudiness and stratiform precipitation if the air is stable, or an increased chance of thunderstorm development if the air is unstable.
Precipitation of liquid water drops greater than 0.5 mm in diameter. In contrast to showers, it is steadier and normally falls from stratiform (layer) cloud.
Rain day
A rain day occurs when a daily rainfall of at least 0.2 mm is recorded.
Warm Advection - Transport of warm air into an area by horizontal winds. This often implies the presence of stratiform lifting in the lower levels of the atmosphere.
Isentropic lift often is referred to erroneously as overrunning, but more accurately describes the physical process by which the lifting occurs. Situations involving isentropic lift often are characterized by widespread stratiform clouds and ...
ground, but they can develop past the troposphere in both temperate and tropical latitudes. They are classified as low clouds and include all varieties of cumulus and cumulonimbus. The opposite in type are the horizontal development of stratiform ...
