Weather Topic: What are Stratus Clouds?
Home - Education - Cloud Types - Stratus Clouds
Next Topic: Wall Clouds
Stratus clouds are similar to altostratus clouds, but form at a
lower altitude and are identified by their fog-like appearance, lacking the
distinguishing features of most clouds.
Stratus clouds are wider than most clouds, and their base has a smooth, uniform
look which is lighter in color than a nimbostratus cloud.
The presence of a stratus cloud indicates the possibility of minor precipitation,
such as drizzle, but heavier precipitation does not typically arrive in the form
of a stratus cloud.

Weather Topic: What are Altocumulus Clouds?
Home - Education - Cloud Types - Altocumulus Clouds
Next Topic: Altostratus Clouds
Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.
