Does anyone know how a stormscope is able to sense the distance to the

It counts the difference between the flash and the cracking sound.

No, kidding, sorry. Lightning generates radio frequency energy, just like
any electrical current does. So the location solution can be found
just like they find a radio transmitter, by using directional antennas
and paralax.
