cumulus
Let an agent handle cumulus clouds by identification, species and varieties, formation, weather significance and aviation relevance, using WMO cloud classification.
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 handle cumulus clouds by identification, species and varieties, formation, weather significance and aviation relevance, using WMO cloud classification.
A genus of low-level cloud with a detached, dense, heaped form and sharp outlines, often with flat bases and cauliflower-like tops, formed by rising convection currents; fair-weather cumulus can grow into cumulus congestus and cumulonimbus.
What it is for: Weather observation, forecasting and aviation.
It can be identify cumulus and its species; explain how convection forms cumulus; judge when cumulus may develop into storms; use the WMO International Cloud Atlas.
