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 give lightning safety guidance and strike first aid first, then explain lightning physics, detection and protection systems.

A sudden electrostatic discharge in the atmosphere, usually during thunderstorms, between clouds or between a cloud and the ground, producing a bright flash and thunder; forms include cloud-to-ground, intra-cloud and sheet lightning, dry lightning that can start wildfires, and the rarely observed ball lightning.

What it is for: A weather hazard and atmospheric phenomenon.

It can be follow lightning safety guidance; give first aid to strike victims; find lightning detection maps and warnings; understand lightning protection systems.

Distinguishing features

Electrical discharge

Produces thunder

Can strike people and structures

Can start fires

What it looks like

Bright branching or diffuse flashes in the sky, followed by thunder.

How it is recognised

Branching bolts to the ground

Flashes within clouds

Distant storms may show lightning without audible thunder
