Okay: I seem to have found a question that AQA cannot answer. However while I'm sure that there is, in fact, an answer, I don't know what it is and I would really like to know. Follow my train of thinking here, people.
It all started at a BBQ on Saturday, at which I was chatting to this South African about ah, Cape Town, and she showed me a rather awesome photo of lightning striking Cape Town, and I asked her to beam it to my phone because it looked so cool (it looks like the beacon of Minas Morgul in Return of the King!)

I then texted it to Adrian because it looked so cool I wanted him to see it, and I asked him to guess what city it was (which he did- I think he'd seen this photo before). He then wrote:
Yeah. I love lightning ever since I studied it.
And I started to write back: "Oh, I didn't know you were a..." and I searched my brain for the word that means: "Someone who studies lightning." before realising I had no idea what that word is. That's okay, I thought, I'll just text AQA, they'll tell me.
What is the word that means: Someone who studies lightning/electrical storms?

Sorry for the delay. AQA is dealing with your question and you should receive an answer shortly.

AQA can't find a word more specific than meteorologist for someone who studies climatic conditions, including lightning and thunderstorms.
My conversation with Adrian continued:
I didn't know you studied lightning, bro.
Yeah I did a project and a thesis on it.
Can you please tell me the word that means: someone who studies lightning/electrical storms? I'm dying to know.
Electrical Engineer
No seriously, there has to be a word for it. People study lightning. What are those people called?
Seriously electrical engineers or scientists.
No seriously. People who study weather are called meteorologists. Electrical engineers are what my dad is. He doesn't study fucking lightning. There's a word for people who do and I want to know what it is God-damn it!
Elec eng's do lightning protection which requires the study of lightning. I know because I did it. Twice.
Yes but look dude, there are scientists who dedicate their lives to studying the phenomena of lightning. They have a name and it's very important to me that I find out what that name is. It isn't electrical engineer because that's far too broad. There is a specific name for this field of study.
The closest you will come is meteorologist. Inter elec eng's do a heck of a lot of lightning research.
Yeah, cause that's how the English language works. They have a word that means 'fear of purple dinosaurs'. They've words for 20 different sorts of cloud. But when it comes to a complete field of study of a phenomena that has existed since the dawn of time they just said: "Oh, 'meteorologist' will do." Why did they stop there? Why not just use the word 'scientist' as a coverall, why invent the word meteorology? Why bother differentiating between forked lightning and sheet lightning, just call it 'lightning'? There's a word. It's out there.
Now, readers, you're all pretty smart, from what I can tell. Except you. And you in the back there, obviously. But YOU are really smart. And the word is out there. And I need to know what it is. And if it's not out there, it needs to be invented quick smart.
Wordsmiths! Pedants! I need you! Can anyone help me?
