vortex
Let an agent explain vortices, relay physics, kinds and applications from fluid dynamics and meteorology sources, describe the vortices the registry aliases name, and distinguish vortices from turbulence as a whole, from tornadoes as a specific hazard and from vorticity as a field quantity.
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 vortices, relay physics, kinds and applications from fluid dynamics and meteorology sources, describe the vortices the registry aliases name, and distinguish vortices from turbulence as a whole, from tornadoes as a specific hazard and from vorticity as a field quantity.
A region in a fluid where flow rotates around an axis line, occurring at scales from microscopic eddies to atmospheric systems, including whirlpools, smoke rings, wingtip vortices trailing aircraft wings, Dean vortices in curved pipes, Goertler vortices along concave surfaces, atmospheric mesocyclones within supercell storms, dust devils and steam devils over warm water; vortices are central to fluid dynamics, aerodynamics and meteorology.
What it is for: Not applicable; a fluid flow phenomenon.
It can be explain physics; relay kinds and applications; describe named vortices; distinguish related concepts.
Distinguishing features
Rotation around an axis
All scales
Energy transport
Visible markers
What it looks like
Swirling fluid, visible in whirlpools, smoke rings, dust devils and cloud rotation.
Physical character
Kelvin circulation theorem: 1869 year
wake turbulence separation: rules for aircraft spacing note
dust devil height: up to about 1 km - typical large
How it is recognised
Rotating region of fluid flow
Steam devil, wingtip vortices, Dean vortex, mesocyclone, Goertler vortices, dust devil
Turbulence is chaotic flow; tornadoes are violent ground-contact vortices; vorticity measures local rotation
