stratus
Let an agent explain stratus clouds and related layered cloud types, describe their formation and weather significance, support cloud identification, and support learning in meteorology.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain stratus clouds and related layered cloud types, describe their formation and weather significance, support cloud identification, and support learning in meteorology.
A low-level cloud genus forming a uniform grey layer with a fairly even base, often producing drizzle, snow grains or fog when it reaches the ground, with species such as stratus nebulosus and stratus fractus and related layered clouds including altostratus at middle levels and nimbostratus, the thick rain-bearing layer cloud; stratus clouds form when moist air is cooled near the surface or lifted gently, and are classified in the international cloud atlas.
What it is for: Uniform low layer cloud.
It can be explain stratus and related types; describe formation and weather; support identification; support learning.
Distinguishing features
Layered form
Low base
Even appearance
Drizzle-producing
What it looks like
A featureless grey layer, sometimes ragged, often low.
How it is recognised
Uniform low grey layer
Drizzle or fog possible
Stratocumulus has lumpy elements; cumulus is heaped; cirrostratus is high and thin
