Billow Clouds produced by Kelvin-Helmholtz instability
Billow clouds are created from instability associated with air flows having marked vertical shear and weak thermal stratification.

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.
Low clouds
Clouds with bases below 6000 feet and are stratiform or cumuliform in variety.
Low latitudes ...
Low Clouds The bases of these clouds range from near the surface to about 6,500 feet in middle latitudes. These clouds are almost entirely of water, but the water may be supercooled at sub-freezing temperatures.
low clouds: clouds found between the earth's surface and 2 kilometers (0-6500 feet) in all geographic regions. Contains stratocumulus and stratus clouds, and sometimes nimbostratus, cirrus and cumulonimbus clouds.
Billow clouds Broad, nearly parallel lines of clouds oriented at right angles to the wind.
Billow Clouds These are clouds which appear as if they are a series of breaking ocean waves.
Low clouds (Family C)
some low clouds
These are found up to 6,500 feet (2,000 m) and include the stratus (dense and grey). When stratus clouds contact the ground they are called fog.
Billow clouds - bands of cloud stretching across the wind field.
Cap cloud - one that sits still over a mountain ...
Bands of low clouds, arranged parallel to the low-level winds and moving into or toward a thunderstorm. They may indicate the strength of the inflow of moist air into the storm, and, hence, its potential severity.
Cumulus: Low clouds that develop as individual, detached elements with sharp outlines. The cloud has a flat base and bulges upward.
Cumulus stage: The initial stage in the life cycle of a thunderstorm.
Stratus (St) Low clouds that occur as a uniform gray layer stretching from horizon to horizon. They may produce drizzle, and where they intersect the ground, they are classified as fog.
GRUNGE - Haze or low clouds surrounding a region of storms which limits visibility to storm chasers. Sometimes this term is used to describe low clouds, drizzle, and fog common when there is no good storms to chase.
DepressionA region of low atmospheric pressure that is usually accompanied by low clouds and precipitation.Dew pointThe temperature to which the air must be cooled for water vapor to condense and form fog or clouds.
Scud Ragged low clouds, usually stratus fractus. Most often applied when such clouds are moving rapidly beneath a layer of nimbostratus.
They are classified as low clouds, and include all varieties of stratus and stratocumulus. The opposite in type are the vertical development of cumuliform clouds. STRATOCUMULUS A low cloud composed of layers or patches of cloud elements.
A typical Catalina eddy will allow coastal low clouds and fog to persist into the afternoon. A strong Catalina eddy may extend to 6000 feet and these clouds will move through the inland valleys and reach as far as Palmdale.
Warnings of flight hazards, such as turbulence, icing, low clouds and reduced visibility remain most critical for the protection of life and property over the United States from the earth's surface up to 24,000 feet.
There are low clouds (below 2 kilometres), medium clouds (2 -7 kilometres) and high clouds (above 7 kilometres). There are also clouds that stretch long distances through the atmosphere.
It is a sheetlike cloud that does not exhibit individual elements, and is, perhaps, the most common of all low clouds. Thick and gray, it is seen in low, uniform layers and rarely extends higher than 5,000 feet above the earth's surface.
High clouds are primarily composed of ice crystals; Medium clouds are a mixture of water droplets (usually super-cooled) and ice crystals, in varying proportion, and low clouds primarily water droplets, ...
A region of low atmospheric pressure that is usually accompanied by low clouds and precipitation. The term is also sometimes used as a reference to a Tropical Depression.
Depression Storage ...
Ice blink White glare on the underside of low clouds indicating presence of ice which may be beyond the range of vision.
Overrunning - A condition that happens when an air mass moves up and over a denser air mass on the surface. This creates low clouds, fog and steady, light precipitation.
even further to 4 sub-groups describing altitude: 20,000 ft and above are the cirrus or cirro clouds (cirrocumulus, cirrostratus), composed of mostly ice crystals; from 6,500 to 20,000ft are the alto clouds (altostratus, altocumulus); Low clouds ...
High Pressure - An area of a relative pressure maximum that has diverging winds and rotates in the opposite direction as the earth. This is generally indicative of fair weather, with the possibility of low clouds and fog in large water sources ...
When this term is used in weather forecasts (National Weather Service), it is meant to imply 1) no precipitation; 2) less than 0.4 sky cover of low clouds; 3) no other extreme conditions of cloudiness, visibility, or wind; 4) unrestricted visibility; ...
There is considerable upwelling of the colder subsurface waters due to the prevailing southerly winds. Dominant weather in this area includes coastal fog and low clouds.
Low clouds are found up to 6,500 feet and include the stratocumulus and nimbostratus clouds. When stratus clouds contact the ground they are called fog. Vertical clouds, such as cumulus, rise far above their bases and can form at many heights.
The low clouds are stratocumulus, stratus and most cumulus and cumulonimbus bases, and sometimes nimbostratus. 3. A scheme of classifying clouds according to their particulate composition, namely, water clouds, ice-crystal clouds, and mixed clouds.
