What physical aspect of Lightning can I research?

Question

I'm doing a reseach on Physics of Lightning and there is way too much information so I'm trying to figure out how I can narrow it down to one specific topic of lightning that still has physics in it. It's college-level also.
Any Help?

Answer 1

- Heating effect of the discharge
- The flow of electrons within the discharge
- The variety of exotic radiations released by the discharge
- Enhancing public safety in a thunderstorm
- Varieties of weather that enhance the occurrence of thunderstorms
- The energy exchanges involved with the discharge of electricity
- Potential storage mechanisms of lightning discharge (is it possible?)
- The occurrence of discharge between two insulated charge-points
- The interplay of the discharge with environmental pollution
- The development of lightning arrestors

I could go on - but you will probably find that physics can be argued to be present in every possible reaction that you can think of.

I hope you get loads of good ideas

Answer 2

Just pick the one you find the most interesting. Like what actually causes lightning, for example. Or the effects of a lightning strike, to a building, a human, maybe an electrical system or computer network. You could answer why, since electricity flows from negative to positive, and earth would be negative or ground, it appears that lightning comes from the sky to the earth, when that can't be true!
Just a few thoughts, and good luck on your research paper!
